Crankshaft Position Sensor A Circuit

Measure the ohmic values inside the crankshaft position sensor with a multimeter.

Crankshaft position sensor a circuit.

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. This information is used by the electronic control module ecm to control ignition and fuel injection. When something occurs to interrupt the transference of signals you will likely end up receiving an error code. An advanced level scan tool is an important diagnostic tool for p0335.

The crankshaft position sensor is used to monitor how fast the crankshaft is spinning. The crankshaft position sensor ckp measures crankshaft location and relays this information to the pcm powertrain control module. The crankshaft position sensor ckp also known as the crank position sensor is an electronic device used in an engine to record the rate at which the crankshaft is spinning. The pcm uses the crankshaft position sensor and the camshaft position sensor to vary fuel mapping and timing.

Check the repair manual for the correct ohm result. The computer reads this in rpm s. 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. The crankshaft position sensor is a stationary piece but it works with the reluctor ring to determine positioning and voltage.

Error code p0335 is described as crankshaft position sensor a circuit malfunction.
