Where is the ignition control module located on a 1994 Ford Ranger?
Should be located right between the driver’s side headlight and radiator, normally mounted on a large heatsink.
How do you test a Ford ignition Control Module?
How to Test an 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.
- Locate the ignition module positive (+) wire.
- Locate the ignition module negative (-) wire.
Where is the ignition module located on a 1995 Ford Ranger?
You will find the TFI (module) located on the distributor. Will be held on by two screws. If you are replacing this do to a spark problem I would suggest you replace the stator in the distributor also. The stator can short out the module.
What happens when engine control module goes bad?
Engine performance issues If the ECU has any issues, it may throw off the timing and fuel settings of the engine, which can negatively affect performance. A faulty ECU may cause the vehicle to experience a reduction in fuel efficiency, power, acceleration.
Where is the ignition control module located?
In a domestic model, the module sits on, inside, or near the distributor housing. Foreign models will hide their ignitor within the vehicle’s firewall or wheel-well. In case you cannot find the ignition control module in those locations, check the manual or a wiring diagram.
Can an ignition control module be tested?
Can you test an ignition control module? Yes, You can definitely test an ignition control module and using a multimeter is one of the fastest way to do so. What does the ignition control module do?

What is the ohmmeter on a Ford Ranger 4×4?
Connect an ohmmeter between terminals 1 (White/Light blue wire) and 2 (Dark Blue wire). Then depress the 4×4 (2H-4H) switch. The ohmmeter should indicate a low resistance value (less than 50 ohms) while the switch is being depressed. If this occurs, the switch feed to and from the module is good.
What is low resistance on Ford Ranger 4×4?
Connect an ohmmeter between terminals 1 and 3 (orange/light blue wire). Then depress the LOW RANGE switch. The ohmmeter should indicate a low resistance value (less than 50 ohms) while the switch is being depressed. Again, if this occurs, the 4 low switch is good.
Where are the 4×4 lights on a Ford Ranger?
Connect a test lead between terminal number 5 (grey wire) and ground. Turn the ignition switch to RUN and observe the indicator lights. The 4×4 light in the instrument panel and 4×4 light on the switch should illuminate. This indicates the 4×4 hi lights/dash lights are good.
