How does the crankshaft position and camshaft position sensor work?
How does the crankshaft position and camshaft position sensor work?
The crankshaft position sensor (CKP) and the camshaft position sensor (CMP) work together to ensure that your engine runs smoothly. The CKP monitors the speed and position of the crankshaft, while the CMP monitors the speed and position of the camshaft (s). These two sensors each read an individual reluctor or tone ring.
What can cause a cam / crank correlation problem?
Variable valve timing (VVT) system components can cause cam/crank correlation problems as well. These systems are often dependent on oil pressure, so checking the oil level is a good place to start. A plugged or failed oil control valve can also cause VVT problems.
What happens if your crankshaft and camshaft are not synchronized?
If there is a problem with the synchronization of your crankshaft and camshaft, the vehicle will suffer from many obvious symptoms, including: Keep in mind that these symptoms will be in addition to the illuminated check engine light. If the error code was given by a faulty sensor, then you will not experience any of these symptoms.
What should I do if my crankshaft sensor is not working?
The most common solution to this code is the replacement/repair of wiring, followed by replacement of crankshaft/camshaft position sensors if the engine timing is known to be good. Less common solutions include replacement of reluctor rings, or VVT/VCT oil control solenoids. Note that PCM failures are rare.
Where can I find the crankshaft position sensor?
Crankshaft position sensors can be located on the crankshaft pulley (aka harmonic balancer), the flywheel/flex plate, or on the fuel pump on some diesel applications. What are the common causes of code P0016 ?
Variable valve timing (VVT) system components can cause cam/crank correlation problems as well. These systems are often dependent on oil pressure, so checking the oil level is a good place to start. A plugged or failed oil control valve can also cause VVT problems.
How does the Camshaft Position Sensor ( CMP ) work?
The camshaft position sensor (CMP) is used to determine the position of the camshaft (s). It relays this information to the powertrain control module (PCM). The PCM then uses this information to control the fuel injectors, and on some applications, for ignition timing.
If there is a problem with the synchronization of your crankshaft and camshaft, the vehicle will suffer from many obvious symptoms, including: Keep in mind that these symptoms will be in addition to the illuminated check engine light.
