P00A0 Charge Air Cooler Temperature Sensor Circuit Bank 2
Check engine lightOn
EmissionsRelevant
Drive cycleRequired
Limp modeNo
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.
Likely causes
Connector or wiring faulty
Sensor faulty
Supply or ground disturbed
Engine control module faulty
Symptoms
- Check engine light on
- Usually no noticeable symptoms
- Emissions test or readiness check may fail
