If i buy a tech 2 code reader will it pin point what is making the car go into limp mode? i can cancle with my tech 1 runs ok for about a mile then right back in limp. will tech 2 help pin point whats wrong, please help

 

A scan tool does NOT tell you what's wrong with the car !!...just go to Autozone and they will tell you the code if you can't read it...a lot of REP are throttle body related.

 

Ditto, if car is in limp mode, then any scanner should be able to pull the code, while if code is not active (light in dash not on and car not in limp mode) then need a scanner that can pull down to body level to get the code from the history list.

As for limp mode, 99% of the time, either one of the sensors in either the accelerator pedal, or throttle body not jiving against is other sensor. hence both have two sensor each that read backwards of each other in that module. All the sensors have swipers that read against Stat bars,
Think of something like these,


With most of the time, the stat pad just having some corrosion/build up to cause problems with it, or the swipers have gone weak and not applying enough pressure on the bars to make clean contact, to end up with the changing ohms between the two (one rising, the other one falling) at the correct readings before it stated to have problems.

So again, pull codes to see where they are pointing you, and which needs to be corrected. Both modules can be pulled apart to clean and tweak the sensor, but no Joy in regards to the detail of pulling them apart, and if you don't have the skills to do such, then may need to replace the module that is having problems.
As for after market sensor, pretty good luck on after market for the pedal module, but some of the after market TB sensors can be hit of miss.
Also to point out, on your car, the TB needs to have the silver vane, not the gold one. The difference between the two is how the vane opens, and although you can go into the ECM with HP tuner, to make changes to use gold in a silver car, your looking at at least $200 for a shop with HP tuner to make these changes (tuners time, and the cost of tokens for the tuner to use HP tuner on the car in the first place).

 

Thank You so much, i did get a pedal code one time , i will start there, I will let you know were this go's Thank you!

 

Mine was the C180 connector and the PCM connectors, throwing a TAC mismatch code. I cleaned them all with CRC and a wire brush, code went away. The C180 (and c184 drivetrain plug) are above the PCM in the fender liner area

 

Just proof if its an APP code doesn’t always mean it’s a bad sensor !!

 

I unpluged Accelerator cleaned plug , code is gone , Car is running great for now ! THANK YOU EVERBODY Saved me $$$$$

 

Mine wasn't the Accel...but at least I have a spare now!

 

I had the same problem and found the battery terminal was loose. Haven’t had issue since, but I got a new pedal!

 

Hi guys i have same problem on my c6 2005 .but it goes limp mode when i press the paddal more then half way. We changed a lot of parts from the car and last part we changed was the alternator and all the codes went of and the car came good you can rev it full paddal it was ok fo 5 min i sad finaly is fixed after months in the garaged but took it out and same again same problem when you press more dan half a pedal goes to limp mode. The code p060e i dont know what i am going to do more to her .yes i cleaned all grundings new batry new trottelbody. Nearly all sensors, new pedal new olternator new tensionleads new fusebox checked al voltage checked all wireing new ecu cleaned all conecters every part was bought original or from summit racing and still i cant geting it fixed now same times is not recogniseing the key so i changed key battery but sill it dose it the fuel gauge is playing too some times .but with the new alternoter all codes whent away only that code cames up when it goes limp mode p060e code

 

If you read the code setting criteria this may be an ECM issue and not the throttle body.

 

Changed it with a new ecm still same code and still same problem

 

 

As in step 5 below if a P0602 is not set check ECM powers and grounds…and FYI you don’t check ECM grounds with an ohm meter…I would recommend using an old headlight bulb that draws a few amps…I use an 5 amp high beam bulb.

 

 

Thanks guys for the info . Today it doesn't whant to start is nor recogniseing the key i trid to put it inside the gloves box but sil whant start
