My CEL is NOT illuminated.
I was driving in a remote area carving some simple turns at around 30-45 MPH in second gear. As I was reaching the apex of a turn, I was slowly getting on the gas. Then it happened. It felt like the transmission jumped out of gear. But it didn't. The wrench was displayed, and the car had no power. I was far from home, so I thought I was screwed. I slowly pulled off to the side of the road.
My daughter just said just turn off the car and start it again. Thinking I knew cars, I thought to myself that there is no way that is working.
But, I didn't have a choice. I turned off the car. With cell phone in hand about to call AAA, I paused two seconds and started the car right up with no CEL and no wrench. I was stunned. I drove slowly for a while expecting the problem to show up again. It didn't. I then decided to get back to driving to make it happen again. It didn't. HUH?
Again, the CEL and wrench lights are NOT illuminated.
I then used my scan tool to pull codes. I had the following code in history, NOT in pending codes and NOT in current codes:
P2138 - Throttle/Pedal Position Sensor/Switch D/E Voltage Correlation
Unfortunately, the online manual I use don't really discuss this error. I'm about to back-probe the dual TPSs to ensure they have no issues.
Has anyone had this issue? Looking at other posts on the internet, others have experienced this as well, but none of them really told me the issue. They usually just took it in and then end of post. Others say they installed another throttle and got a re-map; parts changing (no likey). And, others say just get a re-map; for me this fix makes no sense since this is a hard error not a mapping error (right?).
Does anyone know the diagnostic procedure for looking into this? Or what resource do you suggest I use to look into this?
