How does a Ford ignition module work on a car?
How does a Ford ignition module work on a car?
The computer then takes the signal and the pulse rate and determines the rpm. The computer sends a signal to the control module when to fire the coil. The control module automatically controls the dwell for sufficient saturation of the coil windings to give the proper spark duration given the rpm in real time without creating undue heat.
Do you need to replace the ignition module?
If the plugs are alright, the module should be replaced. They are not expensive, however, they require a small special tool to remove the torx screws in the module housing. If there was no misfire, but the vehicle is hard to start or stalls, the module should be inspected and replaced if found to be faulty.
When did Ford start using the TFI ignition module?
Ford used the TFI ignition module (thick film ignition) on vehicles from 1983 through the mid-1990s only. The vehicles that used this module had a conventional hall-effect distributor with a separate coil.
What does pulsing mean on Ford ignition module?
The pulsing means the wire from the computer to the ignition control module is good and the computer is working. If it is working, the module is bad. If no pulsing is noted, check the third terminal down for pulses to the computer.

Where is the Ford TFI ignition module located?
Ford used the TFI ignition module (thick film ignition) on vehicles from 1983 through the mid-1990s only. The vehicles that used this module had a conventional hall-effect distributor with a separate coil. The TFI module was located on a flat area on the base of the distributor.
Can a distributor mounted ignition control module be tested?
As you can see from the image of the ignition control module (in the image viewer on the left), the tests apply to the fender mounted Ford ignition control module. If you need to test the distributor mounted Ford ignition control module, click here: How To Test The Ford Distributor Mounted Ignition Control Module (ICM).
Where is the PIP sensor on a Ford ignition?
The PIP sensor is at the heart of this fender mounted ignition control module and ignition system. Here are some useful facts that you should be aware of about the PIP ( Profile Ignition Pickup) sensor: The PIP sensor is located in the distributor. It’s a Hall Effect type sensor.
What does an ignition control module actually do?
An ignition control module is a component that can regulate spark generation in many internal combustion engines. The main purpose of the ignition module is typically to open or close a ground circuit to the primary winding inside the ignition coil. When this occurs, the coil can generate sufficient voltage to fire a spark plug.
How can I test my ignition control module?
- Remove one plug wire at the spark plug and insert an old spark plug into the end of the plug boot.
- Check for voltage at the coil positive terminal when the ignition key is on. Place the red lead of the multimeter on the positive coil terminal.
- ) wire.
- Locate the ignition module negative (-) wire.
Where do you find the ignition module?
On some cars, the ignition module may be housed on or inside the distributor . In other cases, it may be a standalone unit, or it may be integrated into the ignition coil assembly. The ignition module is easy to access and replace on some vehicles, but on others, it’s buried deep inside the engine compartment .
What is the ignition control module on a car?
An ignition coil is the coil in a vehicle’s ignition system used to convert sufficient voltage to spark the spark plugs. The ignition control module helps manage the electrical current used by the ignition coil.
What kind of ignition system does a Ford Explorer have?
Here’s a simplified ignition system wiring diagram of the 1992, 1993, 1994 4.0L Ford Explorer and 4.0L Ford Ranger. You’ll find part two in the next page. The ignition system, on these particular vehicles, is a Waste Spark System. Which in plain English means that two cylinders get spark at the exact same time.
Is the Ford ignition control module interchangeable?
These ignition control modules (ICM) are not interchangeable but are tested in the exact same way. Also, the photos (in the image viewer) show some of the tests performed on a V8 engine. This might make you think that they don’t apply to your 3.0L, 3.8L V6.
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:
As you can see from the image of the ignition control module (in the image viewer on the left), the tests apply to the fender mounted Ford ignition control module. If you need to test the distributor mounted Ford ignition control module, click here: How To Test The Ford Distributor Mounted Ignition Control Module (ICM).
What kind of ignition module does a 1993 Ford F150 have?
Applies to: 1992-1993 Ford F150. 1992-1993 Ford F250. 1992-1993 Ford F350. All of the information you need to diagnose a misfire or a no-start problem (caused by the ignition module or the ignition coil). Wiring diagram. Component pin outs. Connector pin outs. Firing order. Ignition system component parts numbers.
