Test Crank Sensor 5.3
Test Crank Sensor 5.3. Known good examples of cam and crank sensor signals! If the voltmeter is equipped with needle probes, the wires at the sensor connector need to be back probed.
Now, touch your dmm red lead to the green (signal) wire on the harness connector or ckp sensor. (bad engineering, stuck sensor, etc) Your dmm should register about 200mv to 300mv.
I Was Showing Code P0341 And The Truck Would Crank And Crank But Not Start Which I Learned Was An Issue With The Camshaft Position Sensor.
The following tutorial will help you to test the crankshaft position (ckp) sensor: Open the hood and locate the crankshaft position sensor. For this procedure a dwell meter, or the equivalent, will be needed.
Properly Functioning Sensor Will Range From 550 To 750 Ohms.
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. You do this by checking the output voltage, with the engine cranking. This also means that this type of crank sensor creates an on/off dc voltage signal that can be easily measured with a multimeter, an oscilloscope, and even an led light.
Using A Magnet To Induce The Cmp Signal.
Now, touch your dmm red lead to the green (signal) wire on the harness connector or ckp sensor. Unplug the camshaft position sensor (cps) connector. Crank the engine for a few seconds.
First, Identify The Power, Ground, And Signal Wires Using Your Vehicle Repair Manual.
If there’s no signal, you have a bad sensor. The sensor is mounted on the front of the engine block to the left of the water pump, or on the main pulley by the flywheel. The scan tool should read between 100 and 500 rpm.
To Be Able To Test The Crank Sensor You'll Need To Remove The Starter Motor.
Convert the settings of the digital multimeter to direct current voltage. If the voltmeter is equipped with needle probes, the wires at the sensor connector need to be back probed. Check for the connector as well and make sure no dirt or mud is in there.
