How to know when to replace your camshaft position?
The same procedure applies for the crankshaft sensor. Diagnose the problem through the process of elimination. Taking into consideration that the cam sensor has a direct effect on the operation of the fuel injectors and the crank sensor on the ignition, check for spark at the plugs. Pull one of the spark plug wires off one of the plugs.
How much does a bad camshaft sensor cost?
In this case, because of an inaccurate reading from a bad camshaft position sensor, more fuel than necessary is injected into the engine which causes your fuel economy to drop. To replace a camshaft position sensor, you can expect to pay anywhere from $120 to $300. Parts alone will run about $50 to $200.
How can I test my crankshaft position sensor?
Here is how you can easily test both your crankshaft position sensor and camshaft position sensor. It’s very important to be able to test these sensor since because they control your ignition and fuel injector pulse and if they fail they could cause a Crank No start condition.

What does a bad camshaft sensor do?
At low speeds a bad camshaft sensor will cause the car’s engine to stall. The engine may also experience an inability to turn over, resulting in the car not starting.
How do you test cam position sensor?
To test the camshaft position sensor, you need a multimeter and a magnet. Connect the sensor to a multimeter and set it to diode or low-resistance function. Use the magnet and pass it in front of the sensor several times.
What does a cam position sensor do?
The CAM sensor or camshaft position sensor’s role is to signal the ECM the camshaft position. The crank and cam sensor operates in sync with eachother. The CAM sensor is frequently used in determining which injector to fire in a sequential system and for the COP or coil on-plug ignition systems coil firing event.
What does a camshaft positioning Sencor do?
The camshaft position sensor works in tandem with the crankshaft position sensor to monitor the engine’s timing which, in turn, affects the efficiency of fuel delivery and the sparking mechanisms. The camshaft position sensor is typically referred to as a CMP; the crankshaft position sensor is typically referred to as a CKP.
What does the ECM know about the crankshaft?
Basically the ECM knows that the camshafts turn at half crank speed. It expects the cam sensor to send signal pulses in time with the crankshaft sensor so the proper cylinders get spark and fuel at the correct time.
How does the ECM relearn the sensor information?
Because of manufacturing changes and differences each sensor is slightly different in signal output and even in where it reads the signal depending on the position of the sensing part inside the actual head of the sensor. The relearn procedure “resets” the sensor information so the ECM can learn the new sensors signal.
How much does it cost to replace a camshaft position sensor?
If you are not replacing the camshaft positioning sensor by yourself and the labor is involved, the cost for replacement would add up another $30 to $130 for the labor, depending on which car shop you’re getting it fixed from.
