Where is the CMP sensor located?
Beneath the timing belt cover is where the CMP Sensor is mounted. The camshaft position sensor can be found in the right side of the engine compartment at the rear of the valve cover.
What is a CMP sensor signal?
A CMP sensor signals one or more fixed camshaft reference positions to the Engine Control Module (ECM), for example, the arrival of a cylinder’s intake stroke. The ECM uses the camshaft sensor signal for accurate timing control of ignition (if a gasoline engine), injection, and variable valve phasing, etc.
How do you clean a CMP sensor?
How do you clean a camshaft position sensor? Spray a small amount of solvent on the sensor. Wipe it dry with another rag. Replace the camshaft sensor, and tighten the screws.
What is the function of CMP sensor?
The camshaft sensor enables the engine control to determine the exact position of the crankshaft drive. This information is required to calculate the ignition point and injection point, among other things.
Can a cam sensor be cleaned?
Cleaning the Camshaft Position Sensor Sometimes, cleaning the camshaft sensor can do the trick and bring back your ride’s optimum performance. After that, take the sensor out and place it on a clean rag. Step 4: Next, spray some aerosol solvent on the camshaft position sensor and then use a new rag to wipe it dry.
Where is the camshaft position ( CMP ) sensor located?
The camshaft position (CMP) sensor is a three wire Hall Effect type sensor that needs power and ground to produce a Signal. The cam sensor is located within the distributor assembly and as such, it’s rotated by the camshaft. This also means that a cam signal is created and sent to the PCM once every two revolutions of the Crankshaft.
How to test the camshaft position sensor ( 1997-1999 )?
In plain English, this means that this type of cam sensor can easily be tested with a multimeter in Volts AC mode. You don’t need a scan tool to test the Ford 4.6L, 5.4L camshaft position sensor (although a scan tool does come in handy to read the diagnostic trouble codes). The aim of this tutorial is to walk you thru’ the whole thing step by step.
How to test the cam sensor diagnostic trouble?
CASE 2: The multimeter DID NOT register the On/Off 12 Volt signal as the engine was manually turned. This means that the camshaft position sensor is not producing a cam signal that the PCM can use. With this test result alone, you can’t condemn the cam sensor just yet.
What kind of ground does the cam sensor make?
The LT BLU (light blue) wire connects to the PCM’s connector pin 91. This wire provides the cam sensor with ground. Once the engine starts to crank, the cam sensor produces an analog volt (AC) signal.
