The Definitive Guide to Crank Sensor Testing for Automotive Technicians

Unplug the sensor. Check for ground on the black/light blue wire. Turn the key on and check for 5v on the other two wires. Plug the sensor in and backprobe. One sign that your crankshaft sensor might be failing is if you find it hard to start your vehicle. The sensor keeps track of the speed and location of the ... This article is a primer that will help you to learn and understand the essentials of testing the Crankshaft Position Sensor (Camshaft Position Sensors too). In the video I go over the wiring and how to test it. You'll need: 10k ohm resistor, Power source (8v or 5v depending on year), Some wire leads, volt meter. The best way to test these is probably just to replace and then compare the readings with the new ones. Is your fuel pressure within the 35-45 psi range? Your magnetic CPS has to have 50thou clearance at the flywheel trigger. Turn the key on and rotate the crank by the crank bolt. Pierce the wires ... Looking at your service manual find the wire that goes to the B+ Measure from this wire to ground for the DC supply voltage. Measurement should ... Set a digital multimeter to the AC minivolts range and crank the engine. A normal reading would be 200mV, but again this should be matched with ... The simplest one, take a multimeter and measure their resistance. If you see something close to 2.4 Kohm they are OK most likely. How to test crankshaft position sensors without any guess work using multiple methods and tools to obtain and analyze sensor signals.
