How to do a crank sensor no start test?
Reconnect the connector to the crank sensor. The crankshaft position sensor must be connected to its electrical connector for this test to work. Ground the black multimeter test lead to a good Ground point on the engine. When everything is set up, have a helper turn the crankshaft pulley by hand in a clock-wise direction.
What happens when the crankshaft sensor is not receiving power?
When the crankshaft sensor is not receiving power, the engine will crank but not start. A digital multi-meter will let you determine whether the crankshaft sensor is receiving adequate power.
Why is my crank sensor not registering 12 volts?
Recheck your connections and try the test again. If the multimeter still does not register 12 Volts, then this result lets you know that the reason that the crank sensor did not produce a signal, in TEST 1, is because the crankshaft position (CKP) sensor is not getting power.
Why is the crank sensor on my Trafic not working?
The Crank sensor doesn’t require power, in fact it Generates it (in a fashion) Sending pulses as the engine rotates. More likely, is the wiring between engine & Nearside wing. On Another forum I frequent, the loom itself was found to be internally corroded. As you seemingly have no power. Check the Connections & fuses on the battery.
What does no power to crank and cam sensor mean?
When tried to start the vehicle I got no spark after testing all sensors and coil packs I found no power to crank and cam sensors tested pcm plug found power to some wires tested ground at plug found other wires were ground. Which wires should be power and which should be ground?

Why is my crankshaft positioning sensor not working?
The sensor should receive this power any time that a driver turns the ignition to the “ON” position. Possible causes for the sensor not receiving power include a blown fuse, frayed wire, a faulty powertrain control module and a bad ground or loose connection.
