Crank senor Hi, how do I find my crank senor

If equipped with a tachometer does it register while cranking engine over ?

control unit check

It doesn't have a crank case senor. Do you mean crank shaft position sensor? It is stuck in the block between the block and the A/C compressor.

this car does not have a camshaft sensor the distributor pick up coil acts as a cam sensor here is crank sensor info the crank sensor is located in front of engine just behind the crankshaft pulley using ohmmeter check resistance between terminals on sensor replace is not within specs cold 1630-2740 ohms hot 2065-3225 ohms if this is not the problem please reply to your post ill monitor it. hope this helps

Check Crank sensor

I suspect you have a bad camshaft sensor. It is part of the distributor. To check, remove distributor cap and rotor (1 screw for rotor) and check for brown dust. If yes, remove slotted wheel and clean optical sensor. If car starts, you need a distributor.

Crank sensor has no affect on system. It is used for back up only.

Can you hear pump run for 5 seconds when you turn key on?

The crank sensor is located on the trans. bell housing.Look behind the engine where the tranny bolts to the block and on top of the bell housing just a little off center you will see the sensor which has 2 bolts mounting it in place.It has a 6in length of wire attached to it with a plug on the end.This sensor reads off the flywheel.Hope this helps.

You say you changed the cam sensor. A1391 code is a crank sensor on the top of the trans. bell housing.

It mounts next to the harmonic balancer on the passenger side of motor,Look under car on the passenger side and the front pulley on the crankshaft,you will see a star or piece with teeth at the back of the crankshaft pulley,you should then see the sensor mounter close to this.This is what the sensor is actually reading is the teeth.

The crank sensor is a well known cause of no spark condition, it is most likely the real problem, the crankshaft sensor for a Jeep 2001 is located behind the starter, you have to remove the starter to gain access, even then it is hard to get at.
