Crankshaft Sensor

[RavzSa]

Hi,

I continuously get the following crankshaft sensor error;

065, Post
Crankshaft position sensor : no magnet or teeth no. implausible.

Verify crankshaft position sensor.
Verify signal polarity.
Segments or solenoid at starter ring gear.
Starter = OPERATE -> voltage > 0,4V A.C.
Starter = IDLING -> voltage > 1V A.C.

The car does not show any of the common symptoms of a faulty crankshaft sensor however would this sensor affect cold starts and performance?

Hi, hope things over in RSA are OK, covid19 wise?

Where did that info come from? The MB test is to check the resistance of the sensor with the engine stationary, then to check with an oscilloscope the pattern when cranking the engine. You could check it running, but will need the MB test loom and a breakout box to do so.

Generally they work, or they don't work so effecting performance should not be an issue. Mind you I have seen an engine where one of the bolts holding the torque convertor on came off and took out a tooth on the flywheel, this gave an odd reading when it hit that tooth. It was diagnosed by looking at the oscilloscope pattern.
