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.

Crankshaft position sensor a circuit.

Check the repair manual for the correct ohm result. This information is used by the electronic control module ecm to control ignition and fuel injection. 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. If you get no results that means there is an open circuit inside the sensor.

The crankshaft position sensor is used to monitor how fast the crankshaft is spinning. The computer reads this in rpm s. The crankshaft position sensor ckp measures crankshaft location and relays this information to the pcm powertrain control module. The pcm uses the crankshaft position sensor and the camshaft position sensor to vary fuel mapping and timing.

Replace the crankshaft position sensor. The crankshaft position sensor is a stationary piece but it works with the reluctor ring to determine positioning and voltage. 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. Error code p0335 is described as crankshaft position sensor a circuit malfunction.

However there are many reasons for this message to occur.
