Put your heads together...
Problem - TCC kicks out on highway after some time and drops out of OD.
21 - TPS low
22 - TPS high
31 - PRNDL
39 - TCC problem
43 - ESC Circuit
58 - PASS (Always)
These codes were taken before any diagnostics were performed. I cleared codes and then test drove for about 15 minutes on the highway. Worked perfectly and then just jumped out of overdrive into 4th and the TCC was not engaging. I went home and checked codes again:
39 TCC problem.
The tranny was doing this before I had it rebuilt 7 months ago. It has gotten worse recently. I have had problems with the TPSs (on the third in as many years).
So what I am wondering before I get out all the wiring diagrams and my DVOM, is has anyone experienced this before?
Boost is way too high (all the time). Even idling, it is just below 0 boost. Accelerating puts it almost to max and heavy accelerating buries it. I get an engine ping (more like a growl) (detonation possibly) when it is hot and on heavy acceleration. Needless to say I have been very careful. This hasn't been all the time because sometimes I will start it up and it will be nice and low and have tons of power. If it was a clogged cat, it would be all the time especially out on the highway. Could it be the bypass solenoid? Suggestions?
Oil pressure gauge runs at mid range at idle but during acceleration buries itself.
I have some work cut out for myself so suggestions and tips are very appreciated.
