P00EE — Intake Air Temperature Sensor 3 Range/Performance, Bank 2

Severity: low Safe to drive

What P00EE means

The engine control module detected that the signal from intake air temperature (IAT) sensor 3 on Bank 2 is out of range or does not make sense compared with other sensors and operating conditions. The sensor is normally a thermistor whose resistance changes with air temperature. The module uses it to adjust fuel delivery, spark timing and other settings. Bank 2 is the side of the engine that does not contain cylinder 1.

Symptoms

  • Check Engine light on
  • Sluggish acceleration or hesitation
  • Worse fuel economy
  • Rough idle
  • Hard starting, especially when cold or hot

Possible causes

  1. Failed intake air temperature sensor 3
  2. Open, chafed or shorted wiring to the sensor
  3. Corroded or loose connector terminals
  4. Oil or dirt contamination on the sensor causing wrong readings
  5. Rarely, a software issue or a faulty control module

How to diagnose

  1. Scan for all codes and freeze frame data, and note any other air temperature sensor codes
  2. Inspect the sensor, connector and harness for damage, corrosion or oil
  3. On a cold engine, compare this sensor's reading with the other IAT and coolant temperature readings; they should be close
  4. Measure the sensor resistance and compare it with the spec for your vehicle
  5. Check the reference voltage (usually 5 V) and ground at the harness connector
  6. Test the signal and ground wires back to the module for opens and shorts
  7. Try a known-good sensor and see whether the reading changes

Common fixes

  • Replace intake air temperature sensor 3
  • Repair or replace the damaged wiring
  • Clean or replace the connector and terminals
  • Update the module software if the manufacturer offers a fix

Questions and answers

What does P00EE mean?

The control module sees the signal from intake air temperature sensor 3 on Bank 2 as implausible or out of range. The sensor or its wiring is the most common cause.

Can I drive with P00EE?

Usually yes for a short time. The engine may run rough and use more fuel, so have it diagnosed soon.

How do I clear P00EE?

Fix the cause first by replacing the sensor or repairing the wiring. Then clear the code with a scan tool; if the fault remains, it will return.

This is general information about the code. The meaning can differ between makes and models: a scan tool and the repair manual for your car will show the exact cause.
