Crankshaft position sensor a circuit.
The crankshaft position sensor ckp measures crankshaft location and relays this information to the pcm powertrain control module.
The crankshaft position sensor is a stationary piece but it works with the reluctor ring to determine positioning and voltage.
However there are many reasons for this message to occur.
Depending on the vehicle the pcm uses this crankshaft position information to time the spark properly or on some systems it is only for misfire detection and does not control spark timing.
Measure the ohmic values inside the crankshaft position sensor with a multimeter.
An advanced level scan tool is an important diagnostic tool for p0335.
Error code p0335 is described as crankshaft position sensor a circuit malfunction.
Check the repair manual for the correct ohm result.
If you get no results that means there is an open circuit inside the sensor.
The pcm uses the crankshaft position sensor and the camshaft position sensor to vary fuel mapping and timing.
This means the vehicle s ecm electronic control module has not yet detected the crankshaft position sensor during the first second of cranking of the engine.
The computer reads this in rpm s.
Replace the crankshaft position sensor.
