That's the wrong sensor Posted by SWEDECAR [Email] ![]() ![]() ![]() In Reply to: Crankshaft Position Sensor Description, Ian Glenday ![]() ![]() |
It is a mess trying to keep them apart since car makers have different names for the two sensor.
They tried to stream line the lingo with OBD2 rules but it is still up in the air.
And they are still wrong in their statement that a failed CMP sensor would unlikely cause a no start since it is a no start scenario that is very likely when the CMP sensor is bad. When the engine is up and running you can usually disconnect that sensor and the engine will still run.
As to answer P.Wäber's question.
The CKP sensor is kind of the heart of the engine and it needs to start sending its pulses to the fuel computer before the fuel computer turns on the power/ground to ignition, fuel injectors and fuel pump.
