How does a 3 wire cam sensor work?
When using engines fitted with 3-wire sensors, the CMP variably hesitates the sensor. The highest mark on the camshaft projections prompts the CMP hesitating the sensor. The distributor engine utilizes the conventional distributor fitted with Hall Effect transistor. The three-wire cam uses a unique Hall Effect device.
How to test a GM 3-wire crank sensor?
The tests shown in this video can be used for any 3-wire cam or crank sensor. The P0336 code was caused by the crank sensor connector being left unplugged. So rather than just plug the sensor back in and clear the codes, I decided to take this opportunity to show you how to test the crank sensor circuit on this car. (1996 GM 3100)
How to test a crankshaft position sensor with multimeter?
How to test a crankshaft position sensor? 1 Here you must first unplug the CKP sensor 2 You should then set your digital multimeter by selecting a low range on the DC voltage scale. 3 Without starting the engine, turn the vehicle’s key to the ignition position. 4 Then you must connect the red wire and the black wire
What kind of crank sensor does GM 3100 have?
There are two crank sensors on these early GM 3100 engines. One is a 2-wire magnetic type sensor that GM calls a 7x crank sensor. (7 pulses per 360 degrees of crank rotation). The second is a 3-wire hall effect type sensor that GM calls a 24x crank sensor (24 pulses per 360 degrees of crank rotation).
How is a 4-20mA sensor connected to a 2 wire sensor?
From above – A 4-20mA sensor is normally connected to a reader device that supplies the DC voltage bias for the 2-wire sensor loop and a load resistor device. The reader measures the voltage drop across the load resistor to determine the amount of current in the loop from the sensor.

What are the cam sensor and crank trigger wires?
If running a magnetic pickup, either a crank trigger or a distributor: To run just a magnetic pickup crank input and no camshaft input, PN 558-303 should be purchased. If a cam sync input will be used as well, it is recommended to use PN 558-306 which will contain wiring for both the crank and cam sensor inputs.
How can I tell if my crank sensor is working?
No spark coming out of any of the 6 spark plug wires. You can check this with a simple spark test and if you’ve got spark, the crank sensor is OK and doing its job. The coil pack will not get any switching signals from the PCM (Powertrain Control Module = Fuel Injection Computer).
What kind of crank sensor does Ford 3.0L have?
The crank sensor on your 3.0L, 3.8L Ford car or mini-van is a two wire reluctor type. Ford labels this sensor as a magnetic transducer type. In plain English, this means that this type of crank sensor creates its own voltage signal without an external power source.
