What it means

P00EE is the generic code for an Intake Air Temperature Sensor 3 circuit range or performance fault on Bank 2. The control unit has seen a signal from this sensor that is implausible, either compared with other temperature sensors or with what the engine conditions would predict. The signal is still within electrical limits, so it is not a plain open or short circuit. Which sensor is 'sensor 3' and where it sits varies by model and engine, so check the manufacturer's information.

Symptoms

Engine warning light on
Poor or hesitant acceleration
Rough running or uneven idle
Hard starting, especially when cold or hot
Increased fuel consumption
Reduced power if the car enters a protective mode

Possible causes

Faulty intake air temperature sensor 3 reading incorrectly or slowly (drift or sluggish response)likely
Corroded, loose or damaged connector terminals, or high resistance in the sensor wiringlikely
Damaged wiring, such as chafing or a poor ground or reference voltage feed, giving a skewed signalpossible
Heat soak or a real temperature problem in the Bank 2 intake path, such as a leaking charge air system or a failing intercooler or charge air cooler affecting readingspossible
Sensor fitted in the wrong position, or contaminated with oil or debrispossible
Fault in the control unit input circuit or an outdated software calibration where the manufacturer has issued a known fixrare

How to diagnose

Read all stored and pending codes and the freeze frame data, noting engine temperature, load and ambient conditions when the fault set
Check for related temperature sensor codes and for any manufacturer technical bulletins for the model and engine
Inspect the sensor, connector and wiring on Bank 2 for damage, corrosion, moisture, oil contamination and loose fit
With the engine cold and left to stand, compare the live data from sensor 3 with the other intake air, coolant and ambient temperature readings, which should be close
Watch the live reading as the engine warms and under load to see if it is stuck, drifts or responds too slowly
Check the sensor resistance against the manufacturer's temperature table, and test the wiring for continuity, shorts and voltage drop
Inspect the Bank 2 charge air path, hoses and cooler for leaks or heat problems that could change the true air temperature

How to fix

Replace the intake air temperature sensor 3 if its readings are out of specification or slow to respond
Repair or replace damaged wiring and clean or renew faulty connector terminals
Fix leaks or faults in the charge air system or cooler on Bank 2 if they are affecting the air temperature
Clean off contamination and refit the sensor correctly, using a new seal if required
Apply a software update only if the manufacturer lists an outdated calibration as the cause, and consider control unit repair only after all other causes are ruled out

Can I keep driving?

Low severity

The car can usually be driven for a short time, but book it in soon as the engine may run poorly or use more fuel. If power is noticeably reduced or the engine runs badly, limit driving and have it checked promptly.
