How does a crankshaft position sensor work and where to find it?
The faster the sensor is turning on and off, the faster the crankshaft is spinning. While these Hall effect sensors give a digital signal, some crankshaft position sensors produce an analog signal. They still operate on magnetism, though.
What is the diagnostic code for a bad crankshaft sensor?
There are many diagnostic codes for various problems and they can be checked using a diagnostic scan tool. If the code lies between P0335 and P0338 it indicates that the problem is with the crankshaft sensor. This is one of the simplest ways to diagnose a problem with the crankshaft position sensor.
What happens if your crankshaft sensor is out of sync?
If your defective crankshaft position sensor is extremely out of sync, you might have trouble getting your vehicle started. Furthermore, you might have difficulty keeping it started. This is usually only a problem when the problem has persisted for some time, and you likely have various other underlying issues too.
How much does it cost to replace a crankshaft sensor?
The average cost to replace a crankshaft sensor ranges between $150 and $250. However, it’s not uncommon for those prices to skyrocket if you have a higher-end vehicle. That’s because the labor costs are typically between $90 and $110. From there, the rest of the cost comes down to parts.
Which is the crankshaft position sensor on the engine?
The crankshaft position sensor (CKP sensor or CPS) is one of several sensors that keep your engine running smoothly.
How to test a crankshaft position sensor using a DMM?
Testing a Hall Effect Type CKP Sensor Testing a Hall effect type sensor is best using an oscilloscope. But not many DIYers own one. Still, you can use a DMM to test this type of CKP sensor in your vehicle.
How does a Hall effect sensor work on a crankshaft?
A Hall effect sensor produces electricity in when it is exposed to a magnetic field. In a crankshaft position sensor, a toothed wheel, spinning with the crankshaft, disrupts the magnetic field.
How do you test a crank sensor?
Another way to test the crankshaft sensor with a multimeter is by checking the output voltage with the engine cranking. You will need an assistant to do this. Be very careful around moving parts as you do this. Probe the wiring connectors and measure the output voltage in AC millivolts.
