Intake Manifold Runner Position Sensor/Switch Circuit Range/Performance Bank 1

Where it lives

For P2015, start at the sensor the description names. The description of P2015 puts it on bank 1.

Check these first

• A bank 1 runner position sensor that does not track the runner
• High resistance in the sensor signal circuit
• A bank 1 runner that moves less than commanded
• Corrosion at the position sensor connector

What to do next

1. Read bank 1 runner position sensor while commanding the runner
2. Compare the sensor reading to actual runner travel
3. Test the sensor signal circuit for added resistance
4. Check the sensor connector for corrosion
5. Replace the bank 1 position sensor if the runner travels fully
6. Clear the code and retest
