Disconnect the battery ground cable.
Partially drain the cooling system.
Remove the air cleaner outlet tube.

Disconnect the engine harness from the water tube, remove the bolt and position the heater water outlet tube aside.

Disconnect the Camshaft Position (CMP) sensor electrical connector.

Remove the screws and the CMP sensor.

To install, reverse the removal procedure.

Camshaft Synchronizer

NOTE: Ford does not provide a TDC (Top Dead Center) mark or determination procedure for this engine in this vehicle.
ALLDATA users have reported success using aftermarket tools to determine TDC on this engine.

Alignment Gauge, Synchronizer



Rotate the crankshaft until the No.1 cylinder is at Top Dead Center (TDC) of the compression stroke. CAUTION: Do not turn the crankshaft or camshaft during the removal and installation procedure or the fuel system timing will be out of time with the engine and possibly cause engine damage.
Remove the camshaft position (CMP) sensor.

Remove the Exhaust Gas Recirculation (EGR) valve vacuum hose.

Remove the EGR valve tube upper fitting.

Remove the EGR valve and the adapter.
1 Remove the nut and the bolts.
2 Remove the EGR valve and the adapter assembly.

Remove the camshaft synchronizer bolt.

Remove the camshaft synchronizer. NOTE: The oil pump driveshaft might come out with the camshaft synchronizer. If so, retrieve the oil pump driveshaft before proceeding.

Install the Synchro Positioning Tool on the camshaft synchronizer by rotating the tool until it engages the notch in the camshaft synchronizer housing. CAUTION: A Synchro Positioning Tool must be used during the installation of the replacement synchronizer assembly. Failure to follow this procedure will result in the fuel system being out of time with the engine, possibly causing engine damage.

Install the camshaft synchronizer housing assembly so the arrow on the Synchro Positioning Tool is 54 degrees from the centerline of the engine. NOTE: During installation, the arrow on the synchronizer alignment tool will rotate clockwise as the gears engage.

Install the camshaft synchronizer bolt.

Install the EGR valve and adapter assembly.
1 Position the EGR adapter gasket.
2 Position the EGR.
3 Install the bolts.

NOTE: Reuse the EGR valve adapter gasket.

Install the EGR valve tube upper fitting.

Install the EGR valve vacuum hose.
Install the camshaft position (CMP) sensor.

It's located on front of the engine, near the heater outlet tube.

It's held on by two small screws and has a three wire connector going to it. (easy to install). For a picture of the sensor itself go to This will help you to identify the sensor when you see it on the engine.

Have the computer scanned for codes before you repalce the sensor. If a sensor code is the reasonyou're repalcing it, post the code you have here for further info, if you need it.

Mortox, You’re asking your


You’re asking your question at the end of a thread that was started back in 2011. To avoid any confusion, and so your question gets the attention it deserves you need to start a thread of your own. In that thread post EXACTLY what the problem is, and HOW it was determined that the “Cam Sensor” needs to be replaced. Also post ALL “Error Codes” that are set. Don’t forget to post the year, make, model, and engine size of your vehicle as well.


If an "Error Code" is set it DOES NOT necessarily mean that a sensor (any sensor) needs to be replaced. The problem could be with "Circuit Continuity (and or) Connectivity" for the sensor (or sensors) related to the code that is set.

Do you understand what I just said?
Post back if you don't.
