What does the C1322 fault code mean?

[Willis]

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.

My car previously threw a C1322 code, and at first, I thought it was a false alarm. Actually, it means the speed sensor on the left rear wheel stopped working, so the car couldn't tell how fast that wheel was spinning. Common issues fall into three categories: either the sensor is dirty and clogged with metal shavings, the wiring harness got rubbed raw by the tire, or the sensor itself has aged. In my case, it was a rodent-chewed wire that caused a short circuit when it rained. Don't underestimate this issue—it'll trigger the yellow ABS light on your dashboard, and the anti-lock braking might fail during hard stops, especially when driving on mountain roads. Fixing it isn't too hard: start by cleaning the sensor, check the wiring if that doesn't work, and finally consider replacing the part.

Don't panic when encountering C1322 - it's a common wheel speed sensor fault. Specifically, the signal from that small black square module on the left rear wheel is malfunctioning. I've handled several such cases; 80% of the time it's either wiring connection issues or oil/dirt buildup on the sensor head. You can do basic troubleshooting: check if the sensor wiring is scratched and wipe the probe surface clean with your fingers. If the warning light persists, professional diagnosis is needed since this affects the traction control system - especially risky during rainy turns. Repairs typically cost just a few hundred bucks, way cheaper than transmission overhaul. Address it promptly before complete wheel speed failure occurs.
