P0335 Fault Difficulty in Ignition?
2 Answers
P0335 fault difficulty in ignition can be caused by the following reasons: 1. Incorrect starting method, such as not closing the choke when starting a cold engine; 2. Not pressing the float sinker, causing the combustible mixture entering the cylinder to be too lean, or closing the choke when starting a hot engine, or pressing the float sinker multiple times, causing the combustible mixture entering the cylinder to be too rich, leading to spark plug flooding and preventing the engine from starting. In this case, the choke and decompression valve should be opened, or the spark plug should be removed, the engine should be turned over to expel the fuel in the cylinder, and then restarted.
I've encountered the P0335 trouble code before, and the difficulty in starting is really annoying. A faulty crankshaft position sensor or a short circuit in the wiring can prevent the ECU from receiving the correct signal, causing the spark plugs to fire at the wrong time and the engine not to start. Common causes include dust buildup on the sensor, corroded wiring, or damage from rodents chewing through the wires—sometimes even a loose connector can cause this. When checking, first unplug the connector to see if there's oxidation or breakage, then test if the sensor's resistance is within the standard range. If you're not confident in fixing it yourself, take it to a repair shop for diagnosis immediately—don't delay, or you might drain the battery and make things worse. Safety first: if the car won't start, don't force it; call a tow truck to avoid damaging more components and disrupting your daily commute. Regular cleaning of the engine bay can help prevent such issues.
