P00A0
Charge Air Cooler Temperature Sensor Circuit Bank 2
Forced induction / air temperature
Generic OBD-II
Low
What it means
P00A0 means the engine computer has seen an out-of-range or faulty signal from the bank 2 charge-air-cooler (intercooler) temperature sensor circuit. That sensor tracks the temperature of the pressurized intake air after the intercooler on turbo or supercharged engines. It's usually a wiring or sensor problem rather than a mechanical fault.
Low
Can I keep driving? Yes — this is a sensor-circuit fault, so the car will usually run normally, though a turbo or diesel engine may pull back boost or power until it's fixed.
Common symptoms
What you'll notice
- Check-engine light on
- Often no noticeable change in how the car drives
- On some turbo/diesel engines, slightly reduced boost or power
Common causes
Most likely first
- Faulty charge-air-cooler (intercooler) temperature sensor on bank 2Likely
- Open, shorted, or chafed wiring in the sensor circuitCommon
- Corroded or loose sensor connectorCommon
- Sensor reading out of range due to internal failureLess often
How to diagnose & fix
Work through it in order
- Read freeze-frame data and confirm the code is the bank 2 charge-air-cooler temperature sensor.
- Inspect the sensor connector and wiring for corrosion, damage, or a loose pin.
- Compare the sensor's reading against the intake and ambient temperature sensors with a scan tool.
- Replace the charge-air-cooler temperature sensor if it reads out of range with good wiring.
FAQ
Quick answers
Is it safe to drive with P00A0?+
Generally yes — it's a temperature-sensor circuit fault, not a mechanical failure. On a turbo or diesel the engine may limit boost, so fix it before towing or hard driving.
Can I just clear P00A0?+
You can, but it will return unless the sensor or its wiring is repaired, since the computer keeps rechecking the circuit.
