P00A6
Intake Air Temperature Sensor 2 Circuit Range/Performance Bank 2
Fuel & air metering
Generic OBD-II
Low
What it means
P00A6 means the second intake-air-temperature sensor on bank 2 is reporting a value the ECM considers implausible — out of the expected range or not tracking with other temperature readings. It's a sensor performance fault, usually the sensor itself or its wiring. The engine still runs, but fuelling accuracy suffers slightly until it's corrected.
Low
Can I keep driving? Usually driveable — the car will run and start, but the reading is unreliable so fuelling and cold-start behavior can be slightly off until it's fixed.
Common symptoms
What you'll notice
- Check-engine light on
- Often no noticeable driving symptom
- Slightly rough running or hesitation, especially when cold
- Minor drop in fuel economy
Common causes
Most likely first
- Faulty intake air temperature sensor 2 (bank 2)Likely
- Loose or corroded connector at the sensorCommon
- Open or shorted wiring in the sensor 2 circuitCommon
- Poor sensor ground or reference voltageLess often
- Faulty ECM/PCM (rare — rule out sensor and wiring first)Less often
How to diagnose & fix
Work through it in order
- Read freeze-frame data to see the conditions when the fault set.
- With the engine cold, compare the IAT2 reading on a scan tool to ambient and other temp sensors — they should agree closely.
- Inspect the sensor connector and wiring for looseness, corrosion, or damage.
- Measure the sensor's resistance and check that it changes correctly with temperature.
- Replace the sensor if it reads out of range; repair wiring as needed. Clear and re-test.
FAQ
Quick answers
Is it safe to drive with P00A6?+
Generally yes for short trips — it's an air-temperature sensor performance fault, not a no-start condition. Fix it so fuelling stays accurate and to clear the light.
Can I just clear P00A6?+
It will come back once the ECM sees the implausible reading again, so the sensor or wiring needs to be corrected first.
