What does the injector driver module do?

What does the injector driver module do?

The Diesel Injector Driver Module works with your vehicle’s fuel injection system and engine control unit (ECU) to control the fuel injection timing and amount of fuel that enters the ignition valve. It does this by supplying the injector solenoids with a stepped-up voltage to open and close the injection valves.

What is an IDM on a 7.3 Powerstroke?

The IDM (Injector Driver Module) is basically a dumb box that fires the injectors in response to a signal from the PCM telling it which injector to fire, when to fire it, and for how long.

How do I know if my injector driver module is bad?

Symptoms of a Bad or Failing Injector Control Pressure Sensor

1. Starting issues. One of the first symptoms of a possible issue with the injector control pressure sensor is issues starting the engine.
2. Engine misfires and decrease in power, acceleration, and fuel economy.
3. Check Engine Light comes on.

What causes injector driver failure?

When the ECU driver circuit turns on, current flows to ground through the injector solenoid coil. Without this control of the current flow through the injector, the solenoid coil would overheat, causing injector failure.

What happens when fuel injectors go bad?

Dirty fuel injectors may cause your vehicle’s engine to misfire. This problem makes the motor feel as though it is sputtering — sending vibrations through the car. Such misfires can happen when a fuel injector problem mixes up the delicate balance between fuel and air entering the engine.

Are all 7.3 IDM the same?

All IDM’s are completely interchangeable with each other, and any IDM can be used in any model year truck.

How many miles do 7.3 injectors last?

Some can be expected to last between 80,000 and 100,000 miles, while the best fuel injectors can last as long as you have your vehicle. You can expect your fuel injectors to last longer with a little care and attention.

How can I make my 7.3 quieter?

Compared to some diesels the 7.3 is already relatively quiet and that is all it is relative. Work on things that get air out of the system that will make it smoother and quieter. Stick with pump diesel with a little additive or reasonable mix ratio bio-diesel with pump diesel.
