Which speed sensor would probably be the cause of the cruise control to stop working? The brake light switch and all fuses are working fine. EVAP Canister bad and changing today. I would like to get cruise control working at same time.

Hi,

If there is an issue with a wheel speed sensor, the ABS light would be on as well. I attached the wiring schematic below for the cruise control. Check to make sure the fuse I highlighted is good.

Next, if the fuse is good, we need to check the wiring at the PCM to see if there is an issue with the signal from the switches. The PCM is what controls the circuit.

Let me know.

Take care,

joe

See pics below. Note there is a joint connector for the sensor ground. That may have failed as well.
