What is the P0135 Error Code?
The P0135 error code is a specific diagnostic trouble code (DTC) that indicates a problem with the oxygen sensor heater circuit in bank 1 sensor 1. This sensor is located before the catalytic converter and plays a crucial role in managing your vehicle's emissions and fuel efficiency.
Common Symptoms of P0135 in Mazda 6
- Check Engine Light: The most obvious sign is the illumination of the check engine light on your dashboard.
- Poor Fuel Economy: If the oxygen sensor isn't working properly, your car may consume more fuel than usual.
- Rough Idling: You might notice that your Mazda 6 is idling roughly or unevenly.
- Emission Failure: In many regions, a car with an active P0135 error code will fail emission tests.
Diagnosing the P0135 Error Code
To accurately diagnose the P0135 error code in your Mazda 6, follow these steps:
- Use an OBD-II Scanner: Connect an OBD-II scanner to your car's diagnostic port to confirm the presence of the P0135 error code.
