Move the fuel-injectors wiring harness off the valve cover studs as well to gain access to the camshaft sensor if necessary.ĥ. Using a pair of slip joint pliers if necessaryĪny other accessories that might interfere with the removal of theĬamshaft sensor like wiring harness, spark plug retainers or engineĬover, depending on your particular model.Ĥ. The accelerator cable next to the throttle assembly towards the backĪnd top of the engine and remove the shield. Place as you loosen the retaining nut with another wrench. The ground battery cable using a wrench to hold the terminal bolt in but quite satisfying to finish it yourself. Very painstaking job that requires patience and precision. Now you know why they say shops charge $500 in to do this - I think they must take the entire engine out. It takes 10 minutes to undo the bolt a couple ratchet clicks at a time, at least 15 to get the thing to wiggle out, probably 15 minutes to unconnect, reconnect, and snap back to the fram the wire harness, and at least another 10 minutes to ratchet the bolt back in click by click. I think the same socket that undid the horn assembly fit the CKP nut. After that, take off the horn assembly to gain very, very limited access to wedge an extended ratchet into the bowels of the engine. Your going to have to take the Air Filter and the air manifold that runs to the engine off. Almost dead-center in the back of the engine. This V-6 has a very hard to find/hard to reach CKP - it is directly under the Distributor, about 4 inches below, inwards toward the Transaxle 'bell'. Here is a sketch of the sensor to give you an idea what to look for: If you just need to replace the sensor, it is a simple job of unplugging the electrical connector and removing the screws holding the sensor in place.

The CMP sensor & synchronizer/shaft are located behind the intake manifold (i.e., back near the firewall on a Ranger) on the top of the cylinder block. On the 3.0L vulcan engine, the CMP signal is generated by a single Hall-Effect magnetic switch, activated by a single 'vane' spinning around by virture of a synchronized shaft which is driven by the camshaft. Both DIS/EDIS use the CMP signal for synchronizing the firing of sequential fuel injectors. The CMP sensor is used for ignition timing in the Ford DIS igntion system, but not in the EDIS igntion system. The Camshaft Position (CMP) Sensor detects the position of the camshaft in order to identifiy when piston No.

How to determine if these sensors are malfunctioning.

A faulty synchronizer bearing may cause a growling noise and lead to camshaft synchronizer failure. Typically this assembly fails due to exposure to high heat.

Yes, a failing synchronizer can illuminate the malfunction indicator lamp (MIL), and may cause vehicle stalling, loss of power, hesitation, surging, poor fuel economy, or a no-start condition. Will a malfunctioning Camshaft Synchronizer Assembly illuminate the check engine light or affect vehicle operation? The camshaft synchronizer assembly is typically located in the engine cylinder block. The synchronizer is driven off the camshaft, and sends the camshaft rotational position information to the powertrain control module (PCM) to establish injector synchronization and coil firing sequence in distributorless ignition systems (DIS). The camshaft synchronizer assembly consists of a camshaft position sensor mounted on an oil pump intermediate shaft.
