Throttle Position Sensor/Switch G Circuit Intermittent

Where it lives

For P212E, the circuit described runs through the sensor. The description of P212E reports a fault at the sensor.

Check these first

• An intermittent connection at the throttle position sensor G
• Corrosion at the sensor G connector
• A failed throttle position sensor
• Chafed sensor G wiring

What to do next

1. Read throttle position sensor G on a scan tool while wiggling the harness
2. Check the sensor G connector and wiring for corrosion
3. Check the sensor G wiring for chafe
4. Replace the sensor G if the reading jumps
5. Clear the code and retest
