The P0500 diagnostic trouble code tells us there is a fault found with the vehicle speed sensor. The speed sensor is monitored by the ECU and when it fails to operate properly the P0500 code is set. Once the code is set, the Check Engine Light will illuminate on the dashboard.

What causes a P0500 code?
Error Code P0500 is defined as Vehicle Speed Sensor Malfunction, indicating a malfunction in the vehicle speed sensor circuit, which is usually caused by a defective speed sensor or problems in the wiring harness.
How do you fix a speed sensor malfunction?
What is this? Unfortunately, it is impossible to repair the transmission speed sensor as it simply fails. You have to discard it and replace it with a new one. A professional mechanic should help you examine and diagnose the speed sensor system of your vehicle even though the symptoms may seem similar in all cars.
What causes a vehicle speed sensor to malfunction?
Poor vehicle maintenance
Failing to follow your vehicle maintenance schedule can increase the risk of speed sensor failure. This device will not be able to produce correct readings if the magnetic pickup and/or toothed wheel become heavily covered in gunk, particularly old transmission fluid contaminants.
How do you if know if your speed sensor is bad?
When there's no speed signal coming from the sensors, shifting of gears will be a problem because the powertrain control module won't control them correctly. This will make the transmission not work properly. It will either shift more quickly or roughly than expected.
Can you drive a car with a bad speed sensor?
In general, it is unsafe to drive a vehicle with a broken wheel speed sensor. The car's computer will not be able to determine the speed that your vehicle is traveling, so it might apply the brakes at a faster rate than necessary or increase the engine power.
How much does it cost to replace a speed sensor?
It also informs the car's computer how much power needs to be applied to stop the car safely. To replace the speed sensor, you are going to pay, on average, between $330 and $380. The labor should only cost you between $80 and $100, while parts will run you about $265.
Can a speed sensor be cleaned?
The various components of the speed sensors can gather dirt from the road and from the dust that is generated by constant sharp braking. Speed sensors need to be cleaned on a regular basis to avoid damaging the anti-lock braking system.
How do you test a transmission speed sensor?
Disconnect the sensor from the housing on the transmission, as indicated in the repair manual for your car. Disconnect the sensor's wire coupling. Using the multimeter's voltmeter connect the probes to the ground and reference wires in the connector. If no voltage is received, the sensor is faulty.
Do you have to reset ECU after changing speed sensor?
You don't need to reset anything but you can disconnect battery for say an hour if you want to do it.
Does speed sensor affect idle?
Your vehicle may rumble or idle irregularly when you start it, or it may burn more fuel than normal. Also, your vehicle may lose power suddenly due to wrong signals sent from the speed sensor to the fuel system.
What happens if you don't replace speed sensor?
When the Sensor is Broken
If the wheel speed sensor isn't working, it won't send any information to the ECU when there's a problem. The ABS system won't know to begin working and you can lose control of your vehicle and cause a crash.
Can a bad speed sensor cause limp mode?
bad speed sensor alone will not cause trans to go into limp mode.
