Crankshaft position sensor:
Note: Engine design precisely locates Crankshaft Position (CKP) sensor. No CKP sensor adjustment is necessary.

Removal and Installation:
Disconnect negative battery cable. Raise and support vehicle. Remove A/C compressor to gain access. Disconnect crankshaft position (CKP) sensor wire connector from engine harness. See figure 5 . Remove CKP sensor mounting screws. Remove CKP sensor. To install, reverse removal procedure. Tighten fasteners to specification. See torque specifications.

Im having problems with my 2000 F-150 V-6. Whats happening is, I go down the road and my truck starts hesitating. No power feels like its falling apart. I took it in to a local machanic replaced plugs , wire, fuel filter, crank shaft sensor, still no improvements.

What about the coil if it feels like it's missing? Seen a few issues with the coils breaking down. Also have the technician road test with a fuel pressure gauge hooked up, the pump may become weak and when accelerated you are feeling low fuel pressure

I forgot to mention, They also put in a new coil. They told me also that when the check engine light comes on, it gives him a code for the crank sensor. I will tell them about the fuel pressure, like you suggested. When its at an Idle it runs great.

Have they checked the catalytic converters> Also, you said they replaced the crank sensor and that is the code that is still coming up. Have them recheck the sensor to make sure it is good. If it is, have them check the wiring to the sensor as well as the plugs to it. Something could be breaking down in the wiring.

Hey thanks for all your help. Finally figuered it out, It was the cam shaft sensor.

The crankshaft position (CKP) sensor on your 4.6L or 5.4L Ford pick up (SUV or car) is a two wire type CKP sensor that you can easily and accurately test with a multimeter in Volts AC mode.

You don't need a scan tool to test the Ford 4.6L, 5.4L crankshaft position sensor (although a scan tool is a must-have tool now-a-days).

This tutorial will walk you thru' the whole thing step by step.

You can find this tutorial in Spanish here: Cómo Probar El Sensor De La Posición Del Cigüeñal (Ford 4.6L, 5.4L) (at: autotecnico-online.com).

Important Tips And Suggestions

TIP 1: The crankshaft position sensor is located on the timing chain cover. More specifically, it's located to the right (passenger side) of the crank pulley and behind the A/C compressor.

TIP 2: It's very important that the battery on your Ford car (pick up or SUV) must be fully charged for this test. The battery must have enough reserve power to crank the engine easily for several seconds.

TIP 3: You'll need to jack up the vehicle to gain access to the CKP sensor. Use a jack stand to hold the car up in the air. Do not trust the jack! Wear safety glasses to protect your eyes from falling debris. Think safety all of the time!

TIP 4: When the CKP sensor goes bad, you'll get a no-spark no-start condition. So, if you're getting spark from the ignition coil pack or the Coil-On-Plug ignition coils, then you can conclude that the crankshaft position sensor is good and this test will not help you.

Since so many things can cause a ‘cranks but does not start’ condition, the following tutorial may give you some more diagnostic/troubleshooting insights:

Where To Buy The Crankshaft Position Sensor And Save

You can find the crankshaft position sensor for your Ford in any auto parts store. If you're wanting the buy the original Motorcraft crankshaft position sensor, you can buy it online for a whole lot cheaper than somewhere local.

The following links will help you comparison shop for the Motorcraft and after market CKP sensor:

Will the above crankshaft position sensor sensor fit your particular Ford pickup (car or SUV)? Don't worry, once you get to the site they'll make sure it fits (by asking you the specifics of your particular Ford/Mercury vehicle). If it doesn't fit, they'll find you the right one.

The crankshaft position (CKP) sensor is one of the most critical components to get the engine in your Ford car (pick up, SUV, van) started. Since it provides the signal the PCM needs to start injecting fuel and start creating spark.

Here are some specifics of the crankshaft position sensor:

The 4.6L, 5.4L CKP sensor is a two wire variable reluctance sensor. What this means is that:

• It doesn't need an external power source or a Ground source (like in a 3 wire type Hall Effect sensor).
• The CKP sensor creates its own signal (AC Volt signal).

Coil Pack Ignition System: If your specific Ford vehicle has an ignition control module (4.6L coil pack vehicles):

1. Once the engine starts to crank, the CKP sensor produces a CKP signal.
2. The CKP sensor signal is sent directly to the ignition control module.
3. Once the ignition control module gets the CKP sensor signal:
   • The ignition module starts to activate both coil packs.
   • Once the coil packs are activated, they start creating spark for each cylinder.
   • The ignition module also creates a PIP signal which is sent to the PCM (Powertrain Control Module = Fuel Injection Computer).
4. The PIP (Profile Ignition Pickup) signal is the one that the PCM uses to start activating the fuel injectors.
5. And so, with the coil packs creating spark for each cylinder and the PCM activating the 8 fuel injectors, the engine in your Ford vehicle starts.

Coil-On-Plug (COP) Ignition System: If your specific Ford vehicle does not use an ignition control module and is the Coil-On-Plug ignition system type:

1. The crankshaft position sensor signal is sent directly to the PCM.
2. The PCM, once it gets the CKP sensor signal:
   • The PCM activates the Coil-On-Plug ignition coils to start sparking.
   • The PCM activates the fuel injectors.
3. So, with both fuel and spark being fed to each engine cylinder, the engine in your Ford car (or pick up, van, SUV) starts.

In the next section, I'll go into some of the symptoms of a bad CKP sensor.
