What should I do if my speed sensor fails?
If the desired gear and the actual gear do not match, then the PCM will set a diagnostic trouble code (DTC) and illuminate the Check Engine Light or Malfunction Indicator Lamp (MIL). Should either or both of these speed sensors fail, you may notice one or more of the following issues. 1. Harsh or improper shifting
What happens when the transmission speed sensor is lost?
If the signals are lost from the transmission speed sensors, the PCM will set a DTC and illuminate the Check Engine Light on the vehicle dashboard. It also can indicate an increase in tailpipe emissions surpassing acceptable limits for environmental contaminants from motor vehicles.
Can a bad speed sensor affect shift timing?
Harsh or improper shifting. Without a valid speed signal from these sensors, the PCM will not be able to correctly control the shifting of gears within the transmission. This may cause the transmission to shift roughly or more quickly than normal. It’s also common that a problem with these sensors can impact the shift timing,…
What causes a car speed sensor code p0500?
Here are the common causes that trigger code P0500: 1 Defective vehicle speed sensor 2 Problem with the PCM 3 Short or open wire leading to VSS 4 PCM not configured for the tire size being used 5 Damaged drive gear

What are the symptoms of a bad wheel speed sensor?
Symptoms of a Bad or Failing Wheel Speed Sensor Common signs include the ABS Light coming on, ABS not working properly, and the Traction Control Light staying on. by Timothy Charlet on January 13, 2016 1.
What is the name of the transmission speed sensor?
There are generally two speed sensors that work in conjunction to provide accurate transmission data to the vehicle’s powertrain control module. The first is known as the input shaft speed (ISS) sensor. As described, this sensor is used to monitor the speed of the transmission’s input shaft. The other sensor is the output shaft speed (OSS) sensor.
Harsh or improper shifting. Without a valid speed signal from these sensors, the PCM will not be able to correctly control the shifting of gears within the transmission. This may cause the transmission to shift roughly or more quickly than normal. It’s also common that a problem with these sensors can impact the shift timing,…
