Default Constant Check Engine

I have an 02 M. Yellow 6-speed with 8,000 miles on it. I bought it used with 3000 on it.
Since 08-01-02 it has been at the dealers countless times.
In the 1 week I drove less than 100 miles and check engine light came on. Took to dealer with P0172 and P0715 (they said this car has an after market air box). 2 days later check engine light this time took it to the speed shop (found the name on a part on the car). He said he had changed the injectors, so he put the original ones back on (never had codes again). He also put a differnt air box on it, he said it had the wrong one. (no charges).
About 3 weeks later, I go to start my VETTE, it sounds weak starting up, and "Charge system failure" displays and goes away. Also, i had U1160 code during this time. Back to the dealer. they change the Altanator. Same day I left the dealer message agian, later that night. Drove to Orlando for Octobervettes and when I was TRYING to bak into my spot, the car would not go in Reverse. Pushed car into spot, was told you were on a hill everything will be okay. Spend the day at the show, jump in the vette, check engine light, 7 codes PO102, PO418, PO418, PO443, P0449, PO801, PO803. This caused the car not to go into reverse and the crusie control did not work. One dealer said they found an after marker shift eliminator and that it blew fuse 16. They gave me the part and it was melted, they chaged the fuse and said the vette was no longer under warrenty. Same day all 7 codes back, no reverse or cruise again. I called the dealer I bought the vette from and told them the story. They then said no it blew fuse #19, replaced it and sent me on the way. I actually drove it 2000 miles before the problem again. Now the codes are PO102, PO443,PO449, PO801, PO803 and a new code B2605. Dealer called yesterday and said they were replacing an aftermarket shifter that was installed. They called me at 6:00 and said this did not fix the problem. Total days at the shop is now 15 and it is at teh shop now. (NO LEMON LAW since I bough it used) Can any one help, has any one experienced these problems?? I checked the service record on the car before I bough it and it had olny been at the dealer for a noisy driver's door. (I also had this problem and the driver's door was leaking.)

Whew .. slew of problems.. where to start..

First, the codes :

P102 : MAF sensor, low frequency

P172 : Trim Rich > 25%

These codes are certainly inter-related.. for some reason, you have a MAF issue. This could be the result of a poor air box, damaged MAF, a poor attempt at porting, or a leak between the MAF and the Throttle Body. I would swap in a known good MAF to see what happens. Also, inspect the accordian for cracks. If the MAF has been modified (descreened or ported), I'd replace it. The P172 code you are gettting is MAF related.. fix the P102 and the P172 will fix itself..

One question I would have is regarding the tuning in the car.. If in fact it had different injectors, then how was the tuning acheived.. My advise would be to go to the dealer and ask them to flash the PCM back to stock.. that way you know what is going on..

P418 : Air Pump Relay

P443 : Evap Purge Solenoid

P449 : Evap Vent Solenoid

P801 : Reverse Inhibit Solenoid

P803 : Skip Shift Solenoid

All of the above are fed from fuse #19.. the CAGS eliminator that was installed could have blown the fuse. Remove that mod, replace the fuse, and you should be cool.

B2605 : Front Seat Vertical Position Sensor Failure

It's a mystery.. this is fed by the SCM and is apparently just a warranty problem.

Next, the mods :

From all indications, this car may have had a poor choice of product and or worksmanship on some of the mods. The airbox, MAF, CAGS, injectors, and tunign are all suspect. Fortunately, to get you back to stock and start over is fairly cheap..

Regarding the warranty, they cannot blanket void the warranty.. Any damage, and you have none, would have to be caused by the mod. All your stuff is bolt on, and can be corrected.. You should be able to fight the warranty issue and win...

Hope this helps..

Thanks for your reply
I have done nothing to this car, it was sold to me this way. PO172 The rich problem was fixed when the injectors were removed. The fuse was not blown. I checked that before I took it to the dealer.

Can a shifter cause these??
P801 : Reverse Inhibit Solenoid, P803 : Skip Shift Solenoid

They removed an after market shifter but check engine light did not go away. I think they are just finding the mods and not really looking for a problem. Oh they see a girl comming and think I know nothing. Maybe I do not, but I have almost always had sports cars.
90 (chevy) Beretta Indy "Teal"(with some mods, never any problems, great car and pretty fast, 5-speed) sold for
98 (chrysler) Sebring "Gold"(too many problems and slowwwwwww, automatic never again) (not a sports car) soild for
2001 (dodge) Stratus RT "Purple" (pretty fast, 5 speed, some problems) sold for
2002 M. yllow Corvette (went back to chevy, since I had no problems)
also have a 99 Dakota R/T (Dodge) Solar Yellow (big motor 5.9 has a few mods, it is just to heavy.


The speed shop sent me all what was done to the car, $6.000. Now it is almost all gone, oh well not my $6.000.
Still have the exhust, the x-brace, the car is lowered 1 1/4 inches, custom c5 logos, air box, and I think a throrttle body????

2nd dealer is kind of taking care of warranty issue. Teh use car sales mamager is charing it to his account, and I always get a sucky 6-CYL rent-a-car that smells like smoke.

They just called me and said the only code left is the PO102 caused by the air box. Part is on order for the seat. I will go pick it up at 11:45. i just do not believe it is fixed.

Well, keep posting after you get it back..

NO, the shifter cannot cause those problems, but the CAGS eliminator could.

Best of luck.. we'll get you going!

:mad I have been taking it to the dealer where I bought it. I only took it to the speed shop once, because I found out it had bigger injectors, and replaced them. Believe it or Not these are the only codes that have not come back. The constant codes are
P0102 Which the dealer is blaming on the after market air box (PO412, PO418, PO443 and PO449 also). This is the 2nd after market box (two different styles).
The worse two codes are the PO801 and PO803 which the dealer blamed on the after market speed shifter. BUT I just picked up the car Thursday and tonight the codes (all 7) came back. I guess IT WAS NOT the after market shifter. Good thing I made the dealer give it to me in a box.
The worse thing is I went to pick it up Christmas Eve and I had no break Lights, so they kept it till Thursday. They said a wiring harness from the EURO tail lights was melted to the muffler, so they rewired it and secured it to the frame.
:mad I will see them at 9:00 sharp, since the delaer is 45 min. from house. No reverse gear sucks :mad My biggest problem is they are internal shop charging this and giving me problems about the factory warranty. :confused:
So far I have not spent a penny, so wish me luck

Are you sure that used cars don't fall under lemon Laws, after all you did purchase from the dealer, and it is still under warranty????????

Was this a factory buyback? Warranty? press for factory Buyback since it is still under warranty. and bolt ons should not violate the intent of the warranty.....Good luck,

Pass the Pepto......................And demand resolve of issues after all they are the QUOTE professionals and should know how to fix the car..

Call GM and B*tch about the dealer and this sometimes gets there head out of there *ss

DEMAND you will not take the car until fixed.........And also you want a NON SMOKING CAR..........God Bless

"Are you sure that used cars don't fall under lemon Laws"
As Florida Law States Lemon Law is only for new car purchases or Leases. Used cars do not fall under Lemon Law. Just my luck.
Before I purchased the car I had a differnet GM Dealer do a Vin Check on the Vehicle, and it had only been in the shop 1 time for the driver's door to be aligned. I was told this was a common problem. It was sold to the original owner by Dimmit Chevy, sold to a Jaguar dealer, who sold to Bill Heard, where I purchased it. I thought all would be good.

On Saturday it appears it is under warranty. But I told them if they can not fix it "I want a New M. Yellow 6-Speed for the same price I paid for the used one" the guy kinda of laughed. They have a M.Yellow on the lot, but it is and auto and I do not want an auto. (I really do not think this will happen)

In Arizona, the TV stations have a deal, Channel 13 on your side........If you get my drift.

Bad Press many times gets the dealer off there B*tt. Stand your Ground, Demand that your vehicle work properly...Or you will start, Neg. Press

remember these dealers spend millions of $$ for advertising, GOOD GUY press. Negitatve ads/ press......hurt them in the pocket book.

Bill Heard is no different, they are here in Phoenix, They are selling a vehicle with issues.............it is there responsibility to correct them, or BUY Back the vehicle and purchase else where.

You need to call 1(800) 222-1020. This is Chevrolet.......Have your vin#...........and start to factually complain about The work being done @ the dealership......push for resolution, trade to a different vehicle as the one you have is a problem, and might continue to be. With the warranty they have to correct problems if not take vehicle back..........

Line up the NEWS STATION!!!!!!!!!!!!! and start this @ same time double approach, keeps them on there toes, PUSHHHHHH em

Used car dealers.....................are low lifes, they are like dealing with Crack addicts.they lie.

Stand firm and demand results, :boxing

Called several dealers yeaterday to see if I could get a second opnion about the problems, but all three said I should keep it with the dealer I bought it from. I called the original dealer "Dimmit" who sold the car new and the said the "Power trian control had been reprogrammed" in Feb 2002. I am trying to fiqure out why this was done.
It is still at Bill Heard, they did not even me yesterday. I think it is because I did not make them pay for a rent-a-car.
We have an "8 on your side here" I may have to go this route, but first I need to get the car back.
"push for a trade to a different vehicle as the one you have is a problem, and might continue to be." The problem is I looked for 4 years for a M. yellow with both tops and 6-speed, finally found it, and all it has been is a nightmare. :reddevil I do not want any thing but a vette, even after all these problems.
I hate to leave it at the dealer, I know they do not take care of it like me, and I hate others driving it. :nono:
ALL I WANT IS THE CAR FIXED!!!!!!!

FWIW, in addition to the specific problems you mentioned, there may now be problem(s) with the BCM or PCM also.

2000 Pewter Hardtop Thanks for the number to Chevy. I called them on December 31, because My Vette sat at the dealer for three days and no one even looked at it. Once I finished talking to Chevy, I called the dealer and told them I talked to Chevy and all of a sudden, he said,
"we are putting it into the bay right now".
:bs
The dealer called me a couple of hours later to ask a question, but then today they never called me. Funny thing to this is this time I borrowed a car from my parents, and did not make them pay for a rental car. This time they actually kept the Vette long enough to “hopefully” fix the problem.

However, to their surprise Chevy called them this morning, and Then Chevy called me this afternoon. Guess what they told Chevy "It is an electrical problem". Well go figure that is what I have been telling them since October. :smash: :mad :boxing
I called them and they said there was a wire messed up in the wiring harness going to the Tranny. There are 7 wires in this harness and I was getting 7 codes.

Oh well now I am lack of a speed shifter (have it in a box in the garage) and the override of the one to four shift. (I will have to take this up with the dealer when I pick My Vette up) I think they will be doing a reinstall for FREE. :nopity
