What is a vehicle speed sensor circuit?
The Vehicle Speed Sensor, or VSS, sends electrical pulses to the vehicle’s onboard engine computer, also referred to as PCM or ECU, that are generated through a magnet that spins a sensor coil. When the vehicle’s speed increases, the frequency of the pulse increases.
How do you fix a speed sensor circuit malfunction?
What repairs can fix the P0720 code?
- Replacement of the output speed sensor.
- Replacement of the input speed sensor.
- Replacement of the wires or connectors.
- Drain and refill of the transmission fluid.
- Replacement of the PCM.
What could cause your speedometer to stop working?
The most common causes of a speedometer that stopped working include are a faulty speed sensor, a broken gear on the speedometer, damaged wiring, or a faulty engine control unit.
Why does my speedometer and odometer not work?
If both your odometer and speedometer are not working, then it’s likely your speed sensor needs to be replaced. These are easily installed and located near the back of your transmission. If only your odometer is busted, then it’s likely the gears that turn the odometer have broken.
How much does it cost to fix P0500 code?
In total, your bill could be $90 to $185 or more depending on the exact part that needs replacing and the time it takes to install.
What’s the code for a transmission speed sensor?
A P0500 code is a diagnostic trouble code (DTC) titled “Vehicle Speed Sensor (VSS) Malfunction.” This code is triggered when the vehicle’s Powertrain Control Module (PCM) or Engine Control Module (ECM) detects inaccurate speed readings or lack of a signal from the Vehicle Speed Sensor (VSS).
Where is P0500 located?
On front wheel drive cars the speed sensor is often found on the front wheel hub. On rear wheel drive vehicles the speed sensor may be found on the output shaft of the transmission or located within the rear differential.
