Check Engine Light + Trac Off Light + No Overdrive
Posted 07 October 2005 - 07:50 PM
The next day I took it back to the dealer and asked them to re-run dignostics and check out my OD drive problem. This time the tech again pulled code P0330 and stated that the knock sensor needed to be replaced. He cleaned the contacts again and the lights went out. Since I didn't have the $510.00 the dealer wanted for a new knock sensor and the service manager assured me that the engine would not be damaged I decided to pospone the repair and look for a cheaper fix. By the way they couldn't replicate the OD problem and stated the transmission was functioning fine. The lights stayed off for @ three days and OD seemed to be working fine. An unrelated event but interesting anyway. Around two weeks later the battery died and was replaced. The lights went out and stayed out for @ a week.
Now for the wierd part!!! Two weeks later I was driving home on the interstate when suddenly the engine seized the CEL and trac off light were lit and no overdrive. Turns out it threw a rod. Everyone I've talked to assures me that there is no relationship the the CEL / trac off light situation and the engine seizing.
I decided to exchange engines. I found a 2001 engine w/ 35000 mi. and had it installed by a local engine exchange shop. During the test drive the CEL and the trac off light came on. The tech ran diagnostics and cleaned it. The lights went out. About two hours ago I decided to take the car for a test drive, three miles into the drive the lights came back on and I have no overdrive.
WHAT THE HECK SHOULD I DO NOW!!!!!!!!!!!!!!!!!!

are the codes coming off the new engine that same as the codes from previous?
You don't mention what codes were cleared by the tech at the end of you post.

Thanks for the quick response. I don't know if the codes are the same on the new engine as they were on the old. I'll ask the tech on monday. Would the old exhaust manifold and MAF module have been used with the engine swap. My guess is that the old exhaust manifolds with the O2 sensor bank 1 sensor and the O2 bank 2 sensor 1 were used, thus the reason for the CEL / trac off problem still exsisting. I'm not sure if the old MAF module would have been used, but my guess would be no. Any thoughts?

call the place that did the transplant and ask. It is the definative solution.

Fuel system lean, 2 trip logic
When A/F ratio feedbakc is stable after engine warming up, the fuel trim is considerably in error on the RICH side.
(Engine is running lean, fuel trims are out of spec adding fuel)
Knock Sensor 2 Circuit Malfunction
No knock sensor 2 signal to ECM with engine speed 2,000 rpm or more.
They shouldn't have let you out the door without plugging in the tester & going for a 5 min drive. The end result is you blew the engine up just the same as if you were running a 500bhp turbo, or nitrous shot just cruising down the highway. Same damage, just takes longer.
No, when swapping engines, the manifolds & o2 sensors 90% of the time come on the engine as it's easier to leave them there & unbolt the pipe from them. (4 nuts, VS 12)
I would find out what the codes are now. If you don't have a multi-meter to start testing parts, or don't feel like paying bad techs to continue to troubleshoot, just start buying parts from a junkyard.
Start with the MAF.

It has been 3 years, what happened with your transmission? Or does anyone else know about this problem?
I want to test the speed sensors, but the manual does not say how to test them, only how to remove them. Does anyone know how to test a speed sensor?
My car seems to be in "limp" mode, but there are no codes available on my Accutron code reader. Is there a better code reader that can report more?
