Plymouth Voyager Powertrain Control Module

Question: 2001 Chevy Impala

Hello, my check engine light came on this morning so I took my car to auto zone to get a reading. The code that came back is: P0502, Vehicle Speed Sensor circuit condition.

Probable causes:

  1. Poor electrical connection or short circuit condition
  2. Failed Vehicle Speed Sensor
  3. Driving gear mechanical fault

Before the check engine light came on, I was having problems accelerating and my speedometer was not reading correctly mostly at high speeds.

Also, I was having problems with jerking (sometimes) when accelerating at low speeds. (Is this related to the above condition)?
