What does the C1322 fault code mean?
2 Answers
C1322 fault code specific information is as follows: 1. Carbon deposits: Carbon deposits can cause incomplete combustion of gasoline, leading to engine shaking. The impact of engine carbon deposits on a car is significant, reducing engine power, resulting in uneven power output and gradual attenuation. It also increases fuel consumption, adding to the economic burden. 2. Cold start difficulty: That is, difficulty in ignition, making it hard to start the car. Severe carbon deposits in the combustion chamber can even cause cylinder knocking, producing noise during low-speed acceleration, damaging the pistons and crankshaft, and leading to engine overheating, which severely affects car safety. Additionally, it causes excessive emissions, not only failing annual inspection tests but also directly worsening environmental pollution.
I've encountered the C1322 trouble code several times during my last car repair. It usually indicates an issue with the left rear wheel speed sensor. The vehicle uses this sensor to detect how fast the wheel is rotating, and now the data doesn't match the system requirements. There could be several possible causes: the sensor might be clogged with dirt, the wiring connector could be loose or damaged, or the sensor itself might be burnt out. If you've driven through waterlogged roads during rainy or snowy weather, contaminated water seeping in could also damage the circuitry. In the worst-case scenario, you might need to replace the entire sensor assembly. I recommend you promptly retrieve a complete fault record, as this can affect the operation of the ABS and vehicle stability systems. You might feel the steering wheel becoming unresponsive during turns, and braking distances could increase when going downhill. Remember to rinse the inner side of the wheel hubs during regular car washes to prevent this issue.
