How to deal with fault code p0337?
2 Answers
Fault code p0337 can be handled by: going to a repair shop to connect to a computer and check whether the circuit has poor contact. This situation is caused by a problem with the crankshaft position sensor circuit. The function of the crankshaft position sensor is to detect the top dead center signal, crankshaft angle signal, and engine speed signal, and input them into the computer, so that the computer can issue the optimal ignition timing command according to the ignition sequence of the cylinders. There are three main types of crankshaft sensors: magnetoelectric induction type, Hall effect type, and photoelectric type. The magnetoelectric induction speed sensor and crankshaft position sensor are installed in the upper and lower layers in the distributor. The sensor consists of a permanent magnet induction detection coil and a rotor, and the rotor rotates together with the distributor shaft.
Last time my car popped up a P0337 code, which left me stranded on the roadside for half an hour. 'Crankshaft Position Sensor Signal Low' basically means either the sensor itself is faulty or there's an issue with the wiring. Quickly check if the sensor's connector is loose or corroded. Use a multimeter to measure the resistance—normal values should be in the hundreds of ohms; if it's too low, you'll need a new one. If you're doing it yourself, the tools are simple: a Phillips screwdriver and some cleaning spray for the connector. After replacement, reset the fault code and it should be back to normal. Remember, this sensor controls engine ignition—fixing it will make the engine run smoother, otherwise, you might experience stalling or difficulty starting. I proactively check these sensor connectors every year or two as a preventive measure to avoid roadside breakdowns. DIY isn't hard, but for beginners, I recommend searching online for tutorials to learn the steps and ensure safety.
