Crankshaft Position Sensor Circuit Malfunction
The engine computer cannot read the crankshaft position sensor correctly. This can prevent the engine from starting, cause stalling, or make the engine run poorly.
Do not keep driving if the engine stalls, cranks without starting, or runs badly. A bad crankshaft signal can leave you stranded and can cause unsafe driving conditions.
P0335 means the powertrain control module has detected a fault in the crankshaft position sensor A circuit. The PCM uses this signal to determine engine speed and crank position for fuel injection and ignition timing. If the signal is missing, erratic, or out of range, the PCM may disable spark and fuel control or set a no-start condition.
Yes. If the PCM cannot read crankshaft position, it may not allow spark or fuel delivery.
The sensor itself is common, but wiring and connector problems are also very common and should be checked first.
Low voltage can contribute to starting and sensor signal problems, but it is usually not the only cause.
No. If the fault is still present, the code will return and the engine may continue to stall or not start.
