P00ED

What it means

P00ED is the generic code for a fault in the circuit of intake air temperature sensor 3 on bank 2. The engine control unit has seen a signal from this sensor that is outside the expected range, or a wiring or reference voltage problem in its circuit. Which sensor counts as number 3, and where it sits in the intake or charge air path, depends on the engine, so check the model-specific information.

Symptoms

• Engine warning light on
• Poor performance or reduced power, especially under load
• Rough running or hesitation
• Hard starting, particularly when cold
• Higher fuel consumption
• Possible limp mode on some engines with boost control

Possible causes

• Faulty intake air temperature sensor 3 (bank 2)likely
• Damaged, chafed or corroded wiring to the sensor, including a short to earth, short to voltage or open circuitlikely
• Loose, corroded or contaminated connector at the sensor or control unitlikely
• Fault in the sensor reference voltage or earth shared with other sensorspossible
• Heat damage to the sensor or harness near the turbocharger, charge air pipework or exhaustpossible
• Charge air cooler or intake pipework leak or oil contamination affecting the sensorrare
• Internal fault in the engine control unitrare

How to diagnose

1. Read all stored and pending codes and note the freeze frame data, looking for other temperature sensor or reference voltage codes.
2. Check the live data for intake air temperature sensor 3 and compare it with the other intake air temperature readings and coolant temperature on a cold engine; it should be close to ambient.
3. Inspect the sensor, connector and harness for damage, chafing, heat damage, oil, water and corrosion, and check the connector pins for tightness.
4. Wiggle test the harness and connector with the engine idling and watch the live reading for spikes or dropouts.
5. With the ignition off and the connector unplugged, test the wiring for continuity, short to earth and short to voltage against the wiring diagram for that engine.
6. Check the reference voltage and earth at the sensor connector with the ignition on.
7. Measure the sensor resistance at a known temperature and compare it with the manufacturer's specification, or check that the live value changes smoothly as the sensor is warmed.
8. Inspect the intake and charge air pipework for leaks or oil contamination near the sensor.

How to fix

• Replace intake air temperature sensor 3 if it is out of specification or reads implausibly.
• Repair or replace damaged wiring, and secure the harness away from heat and sharp edges.
• Clean, repair or replace a corroded or loose connector and its terminals.
• Repair the shared reference voltage or earth fault if other sensors are affected.
• Fix any intake or charge air leaks or oil contamination, then clear the code and road test to confirm it does not return.
