“I got a P2138 code for Accelerator Pedal Sensor error. From what I have seen this is caused by the two sensors not matching. I have repaired this issue previously about 3 years ago, but it has happened again. This seems to be a common issue with GM cars of this era.”

The vehicle was repaired; however, the failure reoccurred. The dealer was made aware of the failure but provided no assistance. The contact referenced an unknown recall with a similar failure; however, the VIN was not associated. The manufacturer was not made aware of the failure. The failure mileage was unknown.”

Vehicle speed control
41 reports3 crashes
“According to my obd scanner the components that are failed is the throttle body position sensor circuit A & the throttle body position sensor circuit B. Before this happened the check engine light was on for about a week, when I scanned the vehicle with the obd-II the code for a large leak in the fuel EVAP system came up. One day while driving the vehicle I was stopped at a red light and once the light turned green I pressed the gas and the car started to sputter and move very slow also in the driver information center it intermittently showed the warnings service traction control and speed reduced. I had to pull over when safe to do so. Once I got the vehicle home I ran the scan again and it came up with the throttle body position sensor codes. The part is available for inspection. The safety of me and my passenger were in jeopardy we could've definitely been in an accident because it was so sudden when it happened. I have not taken the car to a dealer but an independent mechanic has looked at it. Vehicle has not been inspected by anyone other than me and an independent mechanic. This was a very scary experience and I have seen many forums with the same issues…”
