TEST 1: Testing The CKP Signal With A Multimeter. The crankshaft position sensor is located on the bottom (passenger-side) of the engine timing chain cover. The very first thing you'll need to do is to verify if the crank sensor is producing a crank signal. This is a very easy, but accurate test, that will verify the performance of the CKP sensor. The crankshaft sensor may be an inductive (analog wave) sensor or it may be a Hall-Effect (digital square wave) sensor. Either way, the missing tooth is the most important pulse. The PCM determines the camshaft position angle by recognizing the unique features on the Camshaft tone wheel so that it can identify camshaft angle.
Code P0341 Honda Tech Notes. A damaged or stretched cam chain, resulting from infrequent oil changes, can cause the MIL to come on with DTC P0341 (CMP sensor A and CKP sensor incorrect phase detected). Old oil causes the cam chain to wear quickly. As a result, it stretches beyond the point where the cam chain auto-tensioner can keep up.

The Crankshaft Position (CKP) sensor provides an Engine Control Module (ECM) with its primary timing reference signal. The ECM uses it to calculate the engine speed and position for accurate injection control etc. The signal is also used to detect engine speed anomalies from misfires etc. Unsurprisingly, Hall effect CKP sensors use the Hall

If the CKP or CMP sensor is bad, you'll get no reading. Basic Circuit Description Of A Two Wire Sensor. Since this type of sensor only has two wires and no power supply, testing them is not that hard: One of the two wires is the signal wire that sends the signal to the fuel injection computer of ignition module. The other wire acts as a Ground . 455 492 334 314 146 255 209 203
