P0750

SYMPTOM
P0750 - LR SOLENOID CIRCUIT

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 a test is run in response to a Gear Ratio or Pressure Switch error.

POSSIBLE CAUSES
- Related relay DTC's present
- Intermittent wiring and connectors
- Transmission control relay output circuit open
- L/R solenoid control circuit open
- L/R solenoid control circuit short to ground
- L/R solenoid control circuit short to voltage
- L/R solenoid
- TCM - L/R solenoid
