SYMPTOM
P0801 - REVERSE GEAR LOCKOUT CIRCUIT OPEN OR SHORTED

WHEN MONITORED
Engine at operating temperature, Engine RPM above 608 rpm's, and Vehicle Speed above 5 MPH.

SET CONDITION
Reverse Gear Lockout Solenoid Control circuit is not in the expected state when requested to operate by the PCM. Note: When Vehicle Speed is less then 5 MPH the PCM provides a ground for the solenoid which energizes the solenoid. (Allowing Reverse).

POSSIBLE CAUSES
- Intermittent wiring and connectors conditions
- Open fused ignition switch output circuit
- Open reverse lockout solenoid control circuit
- Fused ignition switch output circuit shorted to ground
- Reverse lockout solenoid control circuit short to ground
