Best Answer

check power and proud to sensor harness: then look at output signal on scope

At sensor then at ecm.most these sensors will require a five volt reference. if this a three wire sensoshould be hall effect type; producing a square wave that should go 5 volts to zero volts.

Where is the crank shaft sensor on a 92 Mazda mx-3?

To the right of the crank shaft pulley. You should see a single black wire going up from the pulley. All you need is a 10MM socket to remove it.


If your crank sensor goes out how do you know which one to change?

There is only one crank sensor fitted, you may also have a cam sensor. the crank sensor is located either around the bellhousing or around the front crank pulley. It either has 2 or 3 wires. It picks the signal off the revolving crank so look for a sensor in the block near flywheel.

Where is the crank sensor on a 98 jeep Cherokee located?

Hey Tony==The crank sensor is on the rear of some jeeps attached to the bell housing. It in itself won't cause overheating. If you have electric fans, make sure they are operating properly. Make sure the radiator is flowing coolant and not have a bunch of build up. Good luck Joe


Your 1998 jeep Cherokee will turn over but wont start and the gas gauge and volt gauge not working?

unplug your crank sensor and see if your gauges start to work some of the time the crank sensor will short and cause a lot of problems if the gauges start to work replace the crank sensor if not look at the 3 wire sensors map tps and o2 sensors one of these vould be the problem also but when you unplug the sensor cycle the key off then on and give it a second and see if your gauges come back if they do mostlikely the last sensor you unpluged is the problem


How do you change a crank position sensor on a Mercedes clk 430?

Well i can only tell you where its located and how to change it on a 2000 Mercedes Benz CLK430 I recently changed mine. The Crank Position Sensor is located under the hood on the Driver side their is a fat black wire that goes down into the crankshaft connecting into the sensor so first you have to unclip the wire to get to the sensor after you've done that you will see the sensor in the shaft you will need a 1/4" socket, extension and ratchet to unscrew the torx screw that connects the sensor to the shaft and a pair of vice grips to wiggle this sensor out since its about 3" long and positioned into the sensor that far down if you need a picture of the engine showing the engine and location of it email me @ Delroyh24@yahoo.com


How do you change a crank sensor on a 1999 Jetta 3 2 0L?

The distributor is the crank sensor. If the timing belt was changed and the check engine light came on, the shaft that drives the distributor could be out of time.


Why would a 1998 Dodge Avenger not start all of a sudden sounds like it is not getting fuel?

== == == == if the car is cranking over you should check a couple things. first check if you have a bad spark plug of wire(the should be replaced at 100,000 miles). second you should check if your fuel pump is bad and see if your injectors are clean. Try checking the crankshaft position sensor or camshaft position sensor if they are bad your car won't crank. (look at coil pack where plug wires are there will be a 3 wire plug going to it put a light tester on the center wire and have a friend crank your car if test light does not stay on the it is probably one of the two sensors mentioned.

Where is the crankshaft sensor located on a 1996 Buick Riviera?

The camshaft sensor is behind the water pump pulley and the crank sensor is mounted just above the crank pulley(dynamic balancer). If the crank sensor is bad . The car will simply DIE. If the cam sensor is bad it will simply not have sequential injector firing and driveability and MPG will be affected.BOBAnswerwhen the water pump pulley is removed you can see a sensor with 3 wires going to it at the top side of the crank shaft pulley. you might be able to see it with a flashlight and a mirror without removing anything. hope that's the right sensor.


How do i Test crank angle sensor?

I believe it is a Hall effect sensor so the best (and only way I know of) is to use an oscilloscope and look at the signal. It should be a square wave. The 3 leads are +5 volts, signal, and ground. You should get a pulse for 4 times for each rotation of the crank as there are 4 spikes on the edge of the pulley. Make sure the distance between the sensor and the spikes on the pulley are approximately .020 inches.
