I am serious, and don't call me Shirley.

Had the Vette all washed, polished, and waxed. Took the kid to her fave restaurant. About an hour later come back out, car struggles to start, chugging about 10 times but finally fires up. Check engine light is on. Swing by Autozone for a free code pull.

Camshaft position sensor bank 1
Crankshaft position sensor bank 1.

Whew. No big deal, should be a cheap-ish fix right?

No.

Wiring harness for the cam sensor is acting up and sensor is still setting off a code after fix. Replace sensor, clear codes, good to go.

Then CEL comes back on, still crankshaft sensor, which they thought was being set off by the cam sensor.

Removal of cam sensor is halted. The sensor won't budge, it's stuck. Service manager calls me. My $400 repair just jumped up to $1800 or more. They've determined the only way to get that sensor out is to remove the timing chain and cover and attempt to get at it from inside.

WTF is this?

wait shirley, you brought your car to autozone for the free code read (not bad yet) and let them do the repairs????? Or did you then take it to a dealer? I'm confused. Regardless, if they don't even know the right procedure to remove the sensor and are "going to try" to remove it by taking the timing chain and cover TAKE IT SOMEWHERE ELSE!!!! Find someone that KNOWS if that's the way to do it or not, not someone who's fishing for a solution..... good luck

Haha! Good catch. No, I took the car to a dealer I know well for the repairs. AZ just pulled the codes-- had to know what was up, just to ease my curiosity. I'd consider another dealer, but these guys are about the best in the area. We don't have a whole lot of world class choices. Besides, I'd just have to pull out the checkbook a 2nd time. The whole situation should've been an hour, in out, pay up, enjoy my oil change, and done. Very frustrating.

gotcha, sucks they can't get it off!!! I hope they try some more before taking off the cover and chain, maybe it'll budge....

ProfessorDeath

Yeah I found that thread along with several others. Passed it along to the service manager, he wrote everything down on my ticket, said the sensor codes are fairly common. A sensor that won't budge was a definite detour.

Also requested they soak in penetrating oil and try to break it loose before tearing my engine apart.

Maybe I'll have 'em cam it while they're in there, save me a project down the road...

...so obviously no warranty remaining ?

if so, that sux... G-L with the repairs.

you need to call this guy:

ProfessorDeath

Unfortunately no warranty, though I talked to the service manager and he's going to work with me on the cost. Hopefully we can keep it low. Will post updates.

Hard to believe the sensor is stuck, Once the bolt is removed there is just one O ring that seals it into the timing cover. Usually just pops out with a little bit of prying. !! There is no need to remove the timing cover, here is a picture of where the sensor is in the timing cover. The sensor cost about $50-$60 Good luck.

ProfessorDeath

yeah the parts are no problem. It's the labor that's the killer. They believe the sensor has swollen up somehow. Very annoying. I will visually inspect the sensor once it's off to verify there is something out of whack and to make sure they're not screwing me.

Yeah, seems like just a little prying would get it off once the bolt is removed.

Looks like just a small o ring...

FortMorganAl

Once the bolt is removed there is nothing holding it in except friction with the O-ring. Pry it out. What's the worst that can happen - you break it? If the O-ring tears and leaves pieces inside then you might have to remove the timing cover to recover them which is where you are now. The construction and removal procedure is in the service manual which this dealer doesn't appear to have. I'd certainly be looking for another dealer who knows what they are doing.

RoadkingC6

but if the timing chain cover has to come off, I assume your putting a new chain on regardless of the miles on the car.

Don-Vette

If its just the O ring holding it in after removing the bolt. Why not soak with some penetrating oil first? But if the whole cover needs to come off replace the chain too.

It's a little late for this advice, but in the future, use Elco Chevrolet in Ballwin. They sell the most vettes in the area, and Bill Galikowski is their vette mechanic who KNOWS vettes. He doesn't have to guess, as he does almost all their vette repairs. Whenever I get my vette worked on there I request that Bill does the work.
I have found Elco to be an excellent dealer, and highly recommend them. I have bought 3 vettes there as well as three Tahoes.

Curious what dealer you are at???

Can anyone recommend a good Corvette dealer for warranty work in the Seattle area?
