P2AEEIntake Air O2 Sensor Pumping Current Circuit High Bank 2
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- How the car detects it
- P2AEE marks the pumping current lead of the bank 2 intake air oxygen sensor as too high. Contact with the heater feed in the shared plug, chafing against a live wire or water that has entered the connector can raise it. On exhaust probes of bank 2, Ford records a battery short of the IP wire as P0152, and CARB obliges the ECM to detect such out-of-range inputs; a code-specific description of P2AEE for the intake side has not been published by any manufacturer. Ford's patent US9441564B2 adds a quirk typical of this sensor: hydrocarbons from crankcase ventilation burn off oxygen at the hot element and distort the reading, but that is a plausibility issue, not an electrical one. Measure the lead against battery voltage before renewing the sensor. P2AED is low, P2AEC open, P2AE5 bank 1.
- What you may notice
