P00A0: Charge Air Cooler Temperature Sensor Circuit Bank 2
Standardized SAE J2012 code · P00xx — Fuel & air metering and auxiliary emission controls
What does P00A0 mean?
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.
The code tells you which monitor failed, not which part is broken. Test before replacing parts.
Symptoms
- Check engine light on
- Usually no noticeable symptoms
- Emissions test or readiness check may fail
Common causes
- High Connector or wiring faulty
- High Sensor faulty
- Medium Supply or ground disturbed
- Low Engine control module faulty
