P00A0Charge Air Cooler Temperature Sensor Circuit Bank 2
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Needs a drive cycle to confirm a fix
- How the car detects it
- The charge air cooler temperature sensor for bank 2 (an NTC thermistor) measures the charge air temperature in the second charge-air path, for example on V engines with two charge air coolers. The engine control module uses it for the air mass calculation, boost control and component protection. For P00A0, this is the general circuit fault; low and high signals have their own codes. No manufacturer description naming this exact code was found. Bank 2 codes occur only on engines with two separate intake or charge-air paths, one per cylinder bank.
