What does the crank sensor on a Ford Ranger do?

The ignition control module on your 2.3L equipped Ford Ranger or Mustang (or Mazda B2300) needs 2 signals from the crank sensor to start sparking the coil packs. One of these two signals is called the CKP signal ( C ran k shaft P osition signal) and the other is called the CID signal ( C ylinder Id entification signal).

Why do I need an ignition coil in my Ford Ranger?

As the component that converts low-voltage currents from your battery to high-voltage power needed by your spark plugs, a Ford Ranger ignition coil is a part your truck can’t live without. Common problems associated with a faulty unit include stalling, power loss, engine noise and trouble starting your vehicle.

How does the ignition module and crank sensor work?

The ignition module now starts to activate the coil packs. During engine cranking, only the Right side spark plugs (exhaust manifold side of the engine) are fired. Once the engine starts, the PCM now commands the ICM to fire both coil packs through the Dual Plug Inhibit (DPI) circuit (circuit 6 of the ICM Top Connector), .

Where are the spark plugs located in the crank sensor?

During engine cranking, only the Right side spark plugs (exhaust manifold side of the engine) are fired. Once the engine starts, the PCM now commands the ICM to fire both coil packs through the Dual Plug Inhibit (DPI) circuit (circuit 6 of the ICM Top Connector), . Each coil pack feeds spark to 4 spark plugs on either side of the engine.

How to test the ignition module and crank sensor?

Since the ICM isn’t cheap and replacing the crank sensor is labor intensive (you’ve got to remove the timing belt), testing the ICM and crank sensor, on your 2.3L Ford Ranger or Mustang (or B2300), becomes a must! For your cross reference information, the ignition control module test that this article covers are:

Can a bad ignition module cause a misfire?

The ignition module has failed. Misfire due to a bad ignition module. Since the ICM isn’t cheap and replacing the crank sensor is labor intensive (you’ve got to remove the timing belt), testing the ICM and crank sensor, on your 2.3L Ford Ranger or Mustang (or B2300), becomes a must!

How is the crank sensor connected to the ICM?

The crank sensor is fed with power and Ground. The crank sensor is a Hall-Effect type sensor. The crankshaft rotation induces the crank sensor to start creating two separate crank signals. One crank signal is called the CKP (crankshaft position) signal. The CKP signal is only sent to the ICM.

Why is the crank sensor on my Ford Ranger not working?

Without voltage, in this wire, the ignition control module, the crankshaft position sensor and both coil packs won’t work. Restoring Power to this circuit should solve your no-spark no-start condition on your 2.3L Ford Mustang or 2.3L Ford Ranger (2.3L Mazda B2300).

What is the wiring diagram for a Ford Ranger?

Wiring Diagram: The following wiring diagram may be of help: 1992-1994 2.3L Ford Ranger Ignition System Wiring Diagram. * Your specific Ford vehicle may have different colors. * Your specific Ford vehicle may have different colors.

What causes a crank sensor to not start?

Now, if the NO START is caused by the ignition module or the crank sensor, usually the ignition coils will not fire any spark at all. Therefore, the second symptom that leads you on the path of a BAD ICM or crank sensor is: No spark at any of the ignition coils.
