P061

Circuit Description

Code P061 will set if the PCM output PO08 is commanding the vent solenoid 'OFF' and the feedback is indicating that it is 'ON' or if the PCM is commanding the vent solenoid 'ON' and the feedback is indicating that it is 'OFF'.

Test Condition(s)

Test continuously.

Failure Condition(s)

1. Cruise vent solenoid commanded 'OFF' and solenoid feedback indicating the solenoid is 'ON' for 0.5 second.
OR
2. Cruise vent solenoid commanded 'ON' and solenoid feedback indicating the solenoid is 'OFF' for 0.5 second.

Action Taken

PCM disables cruise control.

Notes on Fault Tree

1. Checking if the cruise control servo is bad or if the control circuitry is bad. The frequency should cycle between zero and a not-zero number. If the DVM stays at zero, it must be a circuit fault or the PCM.
2. Checking for a short to voltage on CKT 403.
3. Checking CKT 450 for an open.
4. Checking PCM's ability to control the cruise control servo. The voltage should cycle between 0 and 12 volts. If it does, check CKT 403 for an open.
