Volvo 850 Crank Sensor Test

This is according to the test procedure by chilton hayes and volvo.

Volvo 850 crank sensor test.

Cranks but won t start. What else could be going wrong. The crankshaft position sensor ckp is usually a two wire sensor. But the ecu doesn t have an out to the ignition coil power stage.

I do not have an account with alldata. When trying to start it will turn over 3 5 times befo. Thanks for tips on crankshaft sensor test. The rpm sensor and camshaft position sensor have good out.

Nick is a sensor testing wiz. Timing marks on exhaust and intake cams are perfect. March 17 2017. Answered by a verified volvo mechanic.

Crankshaft timing mark is also in perfect alignment. Obd2 code p0336 volvo definition. Casey at pelican parts. I have pulled a p0340 code.

I am testing the camshaft position sensor with a meter plugged into the connector that goes to the ecu. The ckp sensor consists of usually a permanent magnent sensor that is mounted in front of a reluctor toothed wheel mounted to the crankshaft. The ecu ground and power input seem good. A signal and a ground.

I have swap another ignition ecu but no spark either. I followed the volvo ignition test procedure. Followup from the pelican staff. I replace the timing on 1993 volvo 850.
