P2012Fuel & Air Metering

Intake Manifold Runner Control Circuit Low Bank 2

P2012 means the ECM detected a low voltage condition in the intake manifold runner control circuit for Bank 2. This usually indicates a short to ground in the wiring or a shorted actuator.

🚗 Yes, but the runner control fault should be repaired soon.
