As the crankshaft rotates, the sensor produces a pulsed voltage signal, where each pulse corresponds to the tooth on the reluctor ring. The photo below shows the actual signal from the crankshaft position sensor with the engine idling. In this vehicle, the reluctor ring is made with two miss...
When your Chevy Blazer crank sensor begins to fail, it can create a dangerous driving condition for your vehicle. If you own a Blazer... Ten Best Places to Eat at the SEMA Show May 1, 2015 DTC P0335 – How to Test Scion xB Crankshaft Position Sensor October 28, 2015 How To Tes...
Use a multimeter to check the connectors on the fuel injectors. If the voltage isn’t measuring up, there is an issue with the connectors or the wiring. If you’re still having issues, check thecrankshaft position sensor, thecamshaft position sensor, or thethrottle position sensor. If you b...
Step 4 - Temporarily mount the small bulb in a visible area to be seen while driving, masking taped to the hood or dash works well.Step 5 - This test can be used to test all aspects of the wiring circuitry by moving the bulb ground to power. The bulb will now illuminate when the ...
NOTE: If an engine with a COP ignition system cranks normally but won't start because there is no spark, the problem is not one or more bad coils. More likely, the fault is a bad crankshaft or camshaft position sensor, a voltage supply problem to the coils in the ignition circuit, a...
However, it is important to keep in mind, that just because a part is reading bad on the computer, it doesn’t necessarily mean that part is bad. A broken or damaged wire can cause the part to not send the proper signal. If a sensor or part is reading bad, be sure to visually in...
For this reason, the air flow sensor connector terminals as well as the wiring needs to be carefully inspected.Often if an air filter is not installed properly, or the air filter box is not closed, a piece of debris can get sucked into the mass air flow sensor (see this photo) and ...
The water pump is a simple centrifugal pump driven by a belt connected to the crankshaft of the engine. The pump circulates fluid whenever the engine is running. The water pump uses centrifugal force to send fluid to the outside while it spins, causing fluid to be drawn from the cente...

This is done with a belt that runs from your engine’s crankshaft to the power steering pump. Some cars will have just 1 belt that snakes its way through all the pulleys on your engine, called a serpentine belt while other vehicles will have individual belts for each accessory. In either...
