I've gone through the TPS/APPS thread and I do think I have a slightly different question than the threads in that post.
Here is what has happened so far:
So, my questions are:
Here is what has happened so far:
- ( 2023-12-30 ):
- Not more than a few days after replacing the fuel pump (with no problems so far), I completely lost the accelerator while driving.
- during the diagnostic process of the fuel pump issue, I disconnected the battery for an extended period of time and pulled the EFI fuse a few times (which I've read can cause the ECU to "relearn")
- "ECU", "VSC TRAC", "VSC OFF" lights are all on.
- Try accelerator in both Drive and Reverse, nothing happens.
- Turn car off, turn car back on, and accelerator works.
- Not more than a few days after replacing the fuel pump (with no problems so far), I completely lost the accelerator while driving.
- ( 2023-12-31 ):
- Turn key to On position:
- "ECU" and "A/T OIL TEMP" lights on
- Codes: P1120 (APPS) circuit malfunction
- Turn car on (no problem starting):
- "ECU", "VSC TRAC", "VSC OFF" lights are all on.
- "A/T OIL TEMP" light is off
- accelerator pedal works fine (with lights on) in both Drive and Reverse.
- Start car again
- No lights are on
- accelerator works and car appears to be fine.
- Turn key to On position:
So, my questions are:
- Could the loss of throttle/lights going off be a part of the ECU "relearning" process (seems dumb to even ask that but hey...)?
- Is this thing safe to drive? I've lost throttle once before and luckily it wasn't on a highway; I'd rather not repeat that.
- How would ya'll go about diagnosing this when, as of right now, the car works fine?
