Crankshaft Position Sensor A Circuit

The pcm uses the crankshaft position sensor and the camshaft position sensor to vary fuel mapping and timing.

Crankshaft position sensor a circuit.

If you get no results that means there is an open circuit inside the sensor. Replace the crankshaft position sensor. Measure the ohmic values inside the crankshaft position sensor with a multimeter. The crankshaft position sensor ckp measures crankshaft location and relays this information to the pcm powertrain control module.

Check the repair manual for the correct ohm result. 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 computer reads this in rpm s. However there are many reasons for this message to occur.

When something occurs to interrupt the transference of signals you will likely end up receiving an error code. 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. An advanced level scan tool is an important diagnostic tool for p0335. Error code p0335 is described as crankshaft position sensor a circuit malfunction.

This information is used by the electronic control module ecm to control ignition and fuel injection.
