How to Resolve the P0122 Trouble Code?
2 Answers
p0122 trouble code solution: First, inspect the vehicle's fault causes by cleaning the throttle body, checking whether the throttle pedal sensor's connector is loose or the wiring is disconnected, etc. Then, based on the severity of the issue, choose to repair it yourself or go directly to a 4S shop for repairs. After resolving the fault, clear the trouble code. Below is more information about the trouble code: 1. The causes of the P0122 trouble code include an open circuit in the sensor signal circuit, a short circuit to ground in the sensor signal circuit, an open circuit in the sensor reference voltage circuit, a faulty sensor itself, or a fault in the electronic control module (PCM or ECM), etc. 2. After troubleshooting the vehicle, it is generally necessary to clear the trouble codes. When clearing the codes, strictly follow the specific method designated for the vehicle model to clear the trouble codes. Do not arbitrarily remove the battery's negative terminal to clear the car's trouble codes.
Two years ago, the P0122 trouble code lit up on my dashboard while driving. I was quite confused when I first encountered it, but later I noticed that the engine lacked power after starting, and acceleration was particularly sluggish. I tried checking it myself by opening the hood and locating the throttle position sensor, which is near the throttle body and connected by wires and a plug. I checked for any looseness or rust. After unplugging and cleaning the connector, the issue persisted, so I replaced the sensor, which cost around a few dozen yuan to fix. Every time this code appears, the engine idles roughly or even stalls, so timely action is crucial. If there’s an issue with the circuit or the ECU, professional diagnostic tools are needed. DIY repairs can save some money, but if you’re unsure, it’s safer to take the car to a repair shop.
