Code 83, Reverse Inhibit Solenoid - M/T

PCM energizes reverse inhibit solenoid whenever ignition is on and vehicle speed is 4 MPH or less. Code will set if PCM detects the wrong voltage on the monitored circuit for more than 26 seconds; however, MIL will not be turned on.

NOTE: Test numbers refer to numbers on diagnostic chart.

If VSS circuit fails, transmission can be shifted into Reverse. With ignition off, transmission should not shift into Reverse.
Detects a partially shorted coil which could cause excessive current flow. When isolating circuits, leave circuit energized for at least 2 minutes to allow coils to warm.
Raise vehicle enough to access reverse lockout solenoid electrical harness and still be able to turn ignition on.
