Why is my speed sensor not working on my Jeep Cherokee?
If in doubt you can view the speed sensor input in the PCM with a scan tool. The cruise control won’t work if the speed sensor fails. If your cruise control is working the speed sensor is working. Some of the later Cherokees had a corrosion problem with the instrument cluster connector.
Why is my speedometer not working on my Jeep XJ?
The technician at Joe’s Garage determined that the cable is getting 5v at each end–it’s grounded and getting power. This leads him to conclude that the speedometer cable is not the problem, nor the sensor. Instead, he’s diagnosed the instrument cluster as a whole. Does this seem plausible?
Can a transmission speed sensor be removed from a car?
Some speed sensors are internal to the transmission and will require the transmission to be removed from the vehicle before the sensors can be replaced. The most popular service booked by readers of this article is Vehicle Drivetrain Inspection.

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 happens when the output shaft speed sensor falls out?
The other sensor is the output shaft speed (OSS) sensor. If either of these two sensors falls out of alignment or experiences electrical issues, it impacts the operation of the entire transmission.
