Shift Solenoid L Control Circuit Range/Performance
Current through shift solenoid L does not match the commanded value within tolerance. Wiring faults of this kind typically come from chafing, water ingress at connector seals, or pin push-back — a wiggle test on the harness while the code is active often confirms the location.
Affected components
- Shift solenoid l
- Wiring harness
Common causes
- Medium likelihood: Coil resistance drifted
- Medium likelihood: High-resistance contact
- Low likelihood: Sensor element aged beyond calibration window
Possible symptoms
- Check engine or transmission warning light on
- Harsh, delayed, or missing shifts
- Possible limp mode (locked in one gear)
- Slipping or shuddering during gear changes
Diagnostic notes
- The malfunction indicator lamp may illuminate
- Reduced-power or limp mode may occur
