When the signal from this sensor is not available at start-up, it can lead to a variety of issues that can affect the vehicle's performance and emissions.
Common Causes of P124C MINI
- Faulty NOx sensor
- Wiring or connector issues
- ECM communication failure
- Exhaust system leaks
- Contaminated exhaust gases
Symptoms of P124C MINI
- Decreased fuel efficiency
