What should resistance be for VSS speed sensor?
Disengage the wiring harness connector from the VSS. Using a Digital Volt-Ohmmeter (DVOM), measure the resistance (ohmmeter function) between the sensor terminals. If the resistance is 190–250 ohms, the sensor is okay. Vehicle Speed Sensor Replacement REMOVAL & INSTALLATION(older models)
Why is my VSS reading not matching my speed?
Monitor the VSS while driving and see if it corresponds to how fast you are driving. If the reading doesn’t match your actual speed, something is wrong with the sensor or its circuit. If the reading does match but you still have a P0500 code, you likely have an intermittent problem.
How is the VSS sensor used in the PCM?
OPERATION The Vehicle Speed (VSS) Sensor input is used by the PCM to determine vehicle speed. The VSS generates a signal that increases in frequency proportionate to vehicle speed. The PCM has a base frequency stored in memory for a distance of one mile.
What happens when the WSS sensor reads zero mph?
If the circuit suddenly goes open or shows a jump in resistance, you’ve found the fault. If one of the WSS PIDs reads zero mph and the other three are reading vehicle speed, the fault is a bad sensor or a fault in the sensor wiring circuit (keep reading for information on how to check the sensor itself).
Where is my vehicle speed sensor ( VSS ) wire located for?
Where is my Vehicle Speed Sensor (VSS) Wire Located for Radio Installation? When you remove your OEM radio, there are 4 plugs that plug into the radio. Only 2 of the 4 connectors are used with your new aftermarket radio which are the 2 connectors with the larger size pins.
OPERATION The Vehicle Speed (VSS) Sensor input is used by the PCM to determine vehicle speed. The VSS generates a signal that increases in frequency proportionate to vehicle speed. The PCM has a base frequency stored in memory for a distance of one mile.
How is the VSS wire used in cruise control?
Your vehicle’s cruise control uses the VSS wire to determine the vehicle’s speed — it serves the same function for the navigation system. (Don’t substitute the tachometer signal wire for the VSS wire — the tach signal wire sends pulses as long as the engine is running, even when the car is sitting still.)
