P00EDIntake Air Temperature Sensor 3 Circuit Bank 2

Q: What does code P00ED mean?

Intake Air Temperature Sensor 3 Circuit Bank 2. P00ED indicates that the powertrain control module (PCM) has detected an out-of-range signal from the intake air temperature (IAT) sensor 3 on bank 2, which measures the temperature of the air entering that bank of the engine. The PCM compares this reading against expected values and sets the code when the signal voltage or calculated temperature falls outside the normal operating range for a calibrated time.

Symptoms you may notice

Illumination of the check engine light, often with no other noticeable symptoms
Rough idle or hesitation when the engine is cold
Poor fuel economy or rich-running condition
Black smoke from the exhaust due to over-fueling
In rare cases, a no-start condition or stalling after startup
Possible reduced engine performance or power derate

Common causes, most likely first

Faulty intake air temperature sensor 3 on bank 2
Damaged or corroded wiring or connector at the sensor
Open or short circuit in the sensor signal or ground circuit
Intake air leak or obstruction affecting the sensor's reading
Failed mass airflow sensor (MAF) that incorporates the IAT sensor
PCM software or internal fault (less common)

How to diagnose and fix it

Use an OBD-II scanner to verify the code and check live data for the IAT sensor 3 reading
Inspect the sensor and its connector for physical damage, corrosion, or loose pins
Measure the sensor's resistance with a multimeter and compare to the manufacturer's temperature-resistance chart
Check the signal and ground circuits for continuity and shorts using a wiring diagram
Test the reference voltage at the sensor connector with the key on
Replace the intake air temperature sensor 3 if it fails electrical testing
Clear the code and perform a road test to confirm the repair

What most technicians overlook with P00ED

A dirty or contaminated mass airflow sensor can skew the IAT 3 reading even if the sensor itself is good, so always inspect the sensor element for debris.
The IAT sensor 3 on bank 2 is sometimes integrated into the mass airflow sensor or the intake manifold, making it easy to misdiagnose as a separate component.
Wiring harness chafing near the intake manifold or exhaust heat can cause intermittent open circuits that only appear when the engine is hot or vibrating.
A faulty thermostat or cooling system issue can cause intake air temperatures to exceed expected ranges, triggering P00ED without any sensor fault.
After replacing the sensor, the PCM may require a relearn procedure or several drive cycles before the code clears permanently.

Can I keep driving with P00ED?

You can usually continue driving with P00ED, but avoid aggressive acceleration or heavy loads until the fault is repaired, as incorrect intake air temperature readings can affect fuel economy and emissions.
