Accelerator Sensor (aka TPS)
I have an acceleration issue with my car.
I had it scanned, and got code 1542 (which is a Pedal Value Sensor or Throttle Position Sensor)
I've done a good bit of digging - and it looks like the part is called an Accelerator Sensor.
Has anyone replaced theirs?
(My symptoms - after hard acceleration, the car goes into some type of safety mode. Acceleration will be very hesitant and only gradually builds. The car resets itself when you turn it off and back on)

Very common problem. Your car may have a different setup than the 220.
