The Syncroniser IS the sensor. If its not in correctly, it will set a code, and its not easy with out the tool. So put it in EXACTLY like the one you take out. Make marks so that the body and the sensor are right where they were when you started.

SOURCE: replace camshaft sensor and syncronizer

Hello there,

There is some risk to doing it yourself, but only if you do it incorrectly. The cam synchronizer is integral to engine timing, and if the new assembly is not installed with the exact same orientation as the original some serious damage could occur. Luckily, it's not that easy to mess up if you pay attention. The teeth on the bottom of the synchronizer are big enough that the vane rotates approx 10 degrees for each tooth. After removing the sensor from the top of the assembly and before touching the clamping nut that secures the synchro; if you mark the relative position of the synchronizer body on the block, and mark the position of the vane on the synchro body you can install the new synchro in the exact same position. If you make accurate marks and pay attention, it will be obvious if you are off. I replaced mine with this method and have driven approx 150 miles since without a CEL to be seen, nor a squeak to be heard.

However, in replacing the sensor, locate the cam synchronizer there should be a small coolant hose above the harness disconnect the hose pull the spark plug wires from the coil move them out of your way lift up on the wiring harness shroud there are two 5.5 mm bolts holding the sensor to the synchronizer remove the bolts remove the sensor mark the location of the synchronizer on the block and there is a *** inside the synchronizer mark its location to the synchronizer body now remove the 10mm bolt holding the synchronizer to the engine pullup twist counter clockwise it should come right out then get your new synchronizer make the same alignment marks on the new one as you marked on the old one and slide your synchronizer in the hole make sure all your marks line up then do the removal steps in reverse.

In any case you encounter much difficulty in doing these yourself, then contact an auto-technician as soon as possible.

Hope these help.

if you replaced with new parts it sounds like the synchronizer is not is sync and needs to be set correctly.there is a tool to make sure the system is set correctly that you may be able to rent from a tool rental place.

Replaced cam/crank position sensor with no change in rough running engine. Syncronizer has not been replaced. Do I need a tool to syncronize both sensors? It's not been rebuilt or jumped time.

position sensors have little to do with rough running engine
items like bad injectors, problem ignition control module, fuel pressure , HT leads valves, vacuum leaks all contribute to rough running
best run the fault codes first to determine what area to look at and fix the reported faults

I changed out the MAP sensor,and the idle air sensor on my 2006 Ford Taurus. This was before I had the fault code read at a dealer. Code came back as P0340, and P0430 Band 2 cat worn out. I had the cam...

P0340 FORD - Camshaft Position Sensor Circuit Bank 1 Sensor 1Possible causes- Faulty Camshaft Position Sensor
- Camshaft Position Sensor harness is open or shorted
- Camshaft Position Sensor circuit poor electrical connection
- Faulty starter motor
- Starting system circuit
- Dead (Weak) battery
P0340 FORD Description The Camshaft Position Sensor is an electronic device used in an engine to record the rate at which the camshaft is spinning. This information is used by the Engine Control Module(ECM) to control ignition and fuel injection. The camshaft position sensor senses the retraction of camshaft (intake) to identify a particular cylinder. The camshaft position sensor senses the piston position. The sensor system consists of a rotating part, typically a disc, as well as a static part, the actual sensor.

When the engine is running, the high and low parts of the teeth cause the gap with the sensor to change. The changing gap causes the magnetic field near the sensor to change. The change in the magnetic field cause the voltage from the sensor to change.

When the crankshaft position sensor (POS) system becomes inoperative, the camshaft position sensor provides various controls of engine parts instead, utilizing timing of cylinder identification signals.

2003 ford taurus 3.0 Vulcan cranks strong, you can smell the gas but it won't start. I tried replacing the ignition coil with no results.

It is one of two things. Crank shaft sensor, on timing cover, behind crank pulley. Or the camshaft syncronizer, or the camshaft sensor (sits on top of Camshaft syncronizer) Located on drivers side end of engine, in what used to be the home of the old type distributor.

Camshaft sensor is chirpping

Hi, welcome to my name is Shawn and I will be answering your question.

It is not the cam sensor it is the cam syncronizer that needs to be replaced. That is the piece driven by the cam shaft that the cam sensor sits on.

I hope my assistance helped you and resolved your concern, if you need further assistance please ask.

How do you check and change a camshaft position

The camshaft sensor wouldn't explain the clattering noise. But a timing chain would explain both. Clattering from a loose chain and the camshaft sensor code from when the chain broke and the camshafts stopped turning.

The camshaft position sensor and syncro are located on the back of the engine and will sqeek. The syncronizer sits in the engine and is run by the camshaft. the camshaft position sensor sits on top of the syncro and is held down by 2 7/32" screws. If you remove the camshaft position sensor from the top of the syncro and put about 3-5 drops of motor oil in the syncro you may fix your squeek. The syncronizer shaft that goes into the engine will dry out and loose its lubrication causing a squeek/chirp.
I have done this to a few vehicles and had great success.
Hope this helps

Camshaft position sensor

look under the coil pack you will find a round black housing just about where the distributor used to be before they changed over to the coil pack engine

2 screws and this housing comes off and it is the cam sensor

a word of warning the main cause of cam sensor problems is that the magnet in the rotating part
(or as ford calls it the syncronizer ) this magnet comes apart and actually hits the sensor and damages it
if this occurs you have to replace the sensor and the syncronizer this requires a special tool to set
it ( if you do not use the tool you will set a code for cam crank not syncronized

Hope this helps David
