Code 65, Cruise Control Servo Position Sensor: Notes

Code will set if servo position sensor input high circuit is open, grounded or shorted to voltage or if servo position sensor input low circuit is open.

NOTE: Test numbers refer to numbers on diagnostic chart.

Checks if PCM and circuitry to cruise control servo is okay.
Servo position sensor voltage should be 4.6-5.1 volts
Checks integrity or servo position sensor input high and low circuits.
Checks for bad PCM.
