Wastegate Position Sensor A Circuit High

Where it lives

For P2AB9, the circuit described runs through the sensor. The description of P2AB9 reports a fault at the sensor.

Check these first

• A short to voltage on the wastegate position sensor A signal wire
• A failed wastegate position sensor A
• A corroded or wet wastegate position sensor A connector
• A stuck wastegate actuator holding the sensor A arm at one end

What to do next

1. Scan all modules and read wastegate position sensor A voltage
2. Inspect the wastegate position sensor A connector for corrosion or water
3. Test the sensor A signal wire for a short to voltage
4. Check the wastegate actuator moves freely through its full travel
5. Replace wastegate position sensor A if the circuit and actuator are sound
6. Clear the code and retest
