The crankshaft position (CKP) sensor on your 4.6L or 5.4L Ford pick up (SUV or car) is a 2 wire form CKP sensor the you have the right to easily and also accurately test through a multimeter in Volts AC mode.
You are watching: Ford 4.6 crankshaft position sensor location
You don"t need a scan tool to check the Ford 4.6L, 5.4L crankshaft place sensor (although a scan tool is a must have actually tool now-a-days).
This tutorial will certainly walk girlfriend thru" the entirety thing step 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 right (passenger side) that the crank pulley and behind the A/C compressor.
TIP 2: It"s really important the the battery on your Ford vehicle (pick up or SUV) must be fully charged because that this test. The battery need to have enough reserve strength to crank the engine quickly for number of seconds.
TIP 3: You"ll must jack increase the vehicle to gain accessibility to the CKP sensor. Use a jack was standing to organize the car up in the air. Execute not trust the jack! Wear safety glasses to defend your eye from fall debris. Think safety all of the time!
TIP 4: when the CKP sensor goes bad, you"ll gain a no-spark no-start condition. So, if you"re getting spark from the ignition coil pack or the Coil-On-Plug ignition coils, climate you have the right to conclude the the crankshaft place sensor is great and this test will certainly not help you.
Since so countless things can reason a ‘cranks yet does not start’ condition, the following tutorial may offer you some more diagnostic/troubleshooting insights:
Where come Buy The Crankshaft place Sensor and Save
You can uncover the crankshaft position sensor for her Ford in any auto components store. If you"re wanting the purchase the original Motorcraft crankshaft position sensor, you have the right to buy it online for a whole lot cheaper than somewhere local.
The following links will assist you to compare shop for the Motorcraft and also after market CKP sensor:
Will the over crankshaft position sensor sensor fit your details Ford pickup (car or SUV)? Don"t worry, when you obtain to the site they"ll make certain it fits (by questioning you the special, of your specific Ford/Mercury vehicle). If it doesn"t fit, they"ll find you the appropriate one.
How does The Crankshaft place Sensor Work?
The crankshaft place (CKP) sensor is among the most vital components to get the engine in her Ford auto (pick up, SUV, van) started. Since it gives the signal the PCM needs to start injecting fuel and also start creating spark.
Here space some special, of the crankshaft position sensor:
The 4.6L, 5.4L CKP sensor is a 2 wire variable reluctance sensor. What this method is that:It doesn"t require an outside power resource or a Ground resource (like in a 3 wire type Hall effect sensor).The CKP sensor creates its very own signal (AC Volt signal).
Coil pack Ignition System: If your details Ford automobile has one ignition regulate module (4.6L coil load 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 gets the CKP sensor signal:The ignition module starts come activate both coil packs.Once the coil packs are activated, castle start producing spark for each cylinder.The ignition module likewise creates a PIP signal which is sent 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 developing spark for each cylinder and also the PCM activating the 8 fuel injectors, the engine in your Ford vehicle starts.
Coil-On-Plug (COP) Ignition System: If your certain Ford automobile does not usage an ignition regulate module and is the Coil-On-Plug ignition system type:The crankshaft position sensor signal is sent directly to the PCM.The PCM, when it it s okay the CKP sensor signal:The PCM activates the Coil-On-Plug ignition coils to start sparking.The PCM activates the fuel injectors.So, v both fuel and spark being fed to every engine cylinder, the engine in your Ford car (or pick up, van, SUV) starts.
