The crankshaft position (CKP) sensor on your 4.6L or 5.4L Ford pick up (SUV or car) is a 2 wire kind CKP sensor the you have the right to easily and also accurately test with a multimeter in Volts AC mode.

You don"t need a scan device to test the Ford 4.6L, 5.4L crankshaft position sensor (although a scan device is a must have actually tool now-a-days).

This tutorial will walk friend thru" the entirety thing action by step.

Important Tips and also Suggestions

TIP 1: The crankshaft position sensor is situated on the time chain cover. An ext specifically, it"s situated to the best (passenger side) that the crank pulley and also behind the A/C compressor.

TIP 2: It"s very important the the battery on your Ford automobile (pick increase or SUV) should be fully charged for this test. The battery need to have sufficient reserve strength to crank the engine conveniently for number of seconds.

TIP 3: You"ll have to jack increase the auto to gain access to the CKP sensor. Usage a jack was standing to hold the vehicle up in the air. Carry out not trust the jack! Wear safety and security glasses to defend your eye from fallout’s 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 gaining spark from the ignition coil load or the Coil-On-Plug ignition coils, then you can conclude the the crankshaft position sensor is an excellent and this test will certainly not assist you.

Since so plenty of things can cause a ‘cranks yet does not start’ condition, the complying with tutorial may offer you some an ext diagnostic/troubleshooting insights:

Where to Buy The Crankshaft position Sensor and Save

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

The adhering to links will aid you to compare shop for the Motorcraft and after sector CKP sensor:


Will the above crankshaft position sensor sensor fit your particular Ford pickup (car or SUV)? Don"t worry, when you gain to the website they"ll make sure it fits (by asking you the special, of your certain Ford/Mercury vehicle). If that doesn"t fit, they"ll discover you the best one.

How walk The Crankshaft place Sensor Work?

The crankshaft place (CKP) sensor is one of the most an important components to get the engine in your Ford automobile (pick up, SUV, van) started. Because it gives the signal the PCM needs to begin injecting fuel and also start creating spark.

Here space 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 exterior power source or a Ground resource (like in a 3 wire type Hall result sensor).The CKP sensor creates its own signal (AC Volt signal).

Coil pack Ignition System: If your certain Ford car has an ignition control module (4.6L coil pack vehicles):

Once the engine starts to crank, the CKP sensor to produce a CKP signal.The CKP sensor signal is sent straight to the ignition manage module.Once the ignition regulate module it s okay the CKP sensor signal:The ignition module starts to activate both coil packs.Once the coil packs room activated, they start developing spark because that each cylinder.The ignition module also creates a PIP signal i m sorry is sent out to the PCM (Powertrain manage Module = Fuel Injection Computer).The PIP (Profile Ignition Pickup) signal is the one that the PCM provides to begin activating the fuel injectors.And so, through the coil packs producing spark because that each cylinder and the PCM activating the 8 fuel injectors, the engine in her Ford car starts.

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

The crankshaft position sensor signal is sent straight to the PCM.The PCM, as soon as it gets the CKP sensor signal:The PCM activates the Coil-On-Plug ignition coils to start sparking.The PCM activates the fuel injectors.So, with both fuel and spark gift fed to every engine cylinder, the engine in her Ford automobile (or pick up, van, SUV) starts.
