Symptom: P0750-LR SOLENOID CIRCUIT

When Monitored and Set Condition:

When Monitored: Initially at power-up, then every 10 seconds thereafter. The solenoids will also be tested immediately after a gear ratio or pressure switch error is detected.

Set Condition: Three consecutive solenoid continuity test failures, or one failure if test is run in response to a gear ratio or pressure switch error.

POSSIBLE CAUSES

- LR SOLENOID CONTROL CIRCUIT OPEN
- LR SOLENOID CONTROL CIRCUIT SHORT TO GROUND
- LR SOLENOID CONTROL CIRCUIT SHORT TO VOLTAGE
- LR SOLENOID/PRESSURE SWITCH ASSEMBLY
- POWERTRAIN CONTROL MODULE
- INTERMITTENT WIRING AND CONNECTORS
