P0500 PONTIAC Possible Causes
- Faulty Vehicle Speed Sensor
- Vehicle speed sensor harness or connectors is open or shorted
- Vehicle speed sensor circuit poor electrical connection
- Faulty Powertrain Control Module (PCM)
How do I fix code P0500 PONTIAC?
Check the “Possible Causes” listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins.
Cost of diagnosing the P0500 PONTIAC code
The cost of diagnosing the P0500 PONTIAC code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle’s make and model, and even your engine type. Most auto repairs shops charge between $75 and $150 per hour.
When is the code detected
The almost 0 km/h (0 MPH) signal from vehicle speed sensor is sent to Powertrain Control Module (PCM) even when vehicle is being driven.
Possible Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Speedometer may not work properly
- Transmission shifting problem
P0500 PONTIAC Description
A toothed wheel mounted on the output shaft of the transmission generates an AC voltage pulse as it moves past the Vehicle Speed Sensor (VSS). The VSS contains a permanent magnet surrounded by a coil of wire, which produces a magnetic field. The toothed wheel interrupts the magnetic field this generates an AC voltage pulse. As the vehicle speed increases the AC voltage pulse rate also increases. The Powertrain Control Module (PCM) determines the vehicle speed based on the frequency of these pulse signals.
