Transmission Fluid Pressure Sensor/Switch G Circuit Range/Performance
Pressure sensor G is electrically intact, but the readings do not match the model — drift, jumps or values that do not respond to commanded pressure changes.
Affected components
- Transmission pressure sensor g
Common causes
- High likelihood: Aged sensor with offset drift
- Low likelihood: Sensor element aged beyond calibration window
- Low likelihood: Sensor mounting loose - signal damping
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
