Test Crank Sensor Resistance

Test Crank Sensor Resistance. Next, test the sensor circuit by setting your multimeter to “dc volts.” have your helper turn the ignition key on, but don’t start the engine. So you will be avoiding a lot of problems and failures in the future.

A multimeter can measure voltage, current, and resistance. This article will help you to troubleshoot and diagnose a bad crankshaft position sensor on your 4.3l, 5.0l and 5.7l vortec equipped gm pick up or suv. A faulty cam sensor could disrupt the timing of your engine's stroke cycle.

To Measure The Spinning Resistance Of The Crankshaft Sensor Use An Ohmmeter (Multimeter).


Set your multimeter to dc volts to test the sensor’s circuit. Let’s find out the testing process for both of the mechanisms. It's very important to be able to test these sensor since.

As You May Notice, Using A Multimeter To Test The Crankshaft Sensor’s Performance Is Important.


If there’s no signal, you have a bad sensor. Attach one end of the multimeter to each wiring lead of the sensor. You can also check the resistance of the sensor by putting the digital multimeter knob to the ohm scale and connecting both leads of the digital multimeter to the crank sensor wires.

The Readout Should Indicate A Resistance Value, Usually Between 200 And 2000 Ohms, Depending On Your Particular Vehicle Model.


You will get a resistance reading of the crank sensor between 200 and 2000 ohms. If the test results are within specifications, you should check the sensor's electrical connector and the wiring harness. Without a crankshaft position sensor the engine wouldn't start.

For Any Other Reading, Check It Against The Manufacturer’s Specifications.


The crankshaft position sensor evaluates the rotation speed (rpms) and the exact. Take the multi meter and set it to ac volts. So we will choose 20,000 ohms on the selector dial with the help of a multimeter and will take our measurement.

Crankshaft Or Camshaft Position Sensors Usually Come With Voltage Or Resistance Specifications.


In turn, this means nothing more than decreasing the amount of money you will need. Connect one dmm lead to one of the sensor pins and the other dmm lead to the other sensor pin. Here is how you can easily test both your crankshaft position sensor and camshaft position sensor.
