What this code means

The PCM has detected a high-voltage condition on the Tumble Generator Valve 2 left-hand position sensor circuit. This may indicate an open circuit or a short to the reference voltage.

Symptoms

• Check Engine Light
• Minor reduction in fuel economy
• Slightly higher emissions

Common causes

• Open circuit in TGV position sensor wiring
• Disconnected sensor connector
• Faulty TGV position sensor
• Short to voltage in sensor circuit

Diagnostic steps

1. Check TGV 2 LH sensor voltage on scan tool (should not be near 5V reference)
2. Inspect sensor connector for loose or missing connection
3. Test wiring for open circuit or short to voltage
4. Verify sensor ground circuit
5. Replace sensor and retest

Repair notes

Reconnect or replace the TGV position sensor; repair open wiring in the sensor circuit.
