What controls the fuel injector pulse?

What controls the fuel injector pulse?

What controls the fuel injector pulse? At present, the pulse injector operates based on the PWM pulse mode controller. Specifically, the fuel injector will receive a signal from PWM to open the electromagnet and move the piston. From there, under the action of pressure, the fuel will escape in the form of tiny drops.

What would cause injectors not to fire?

So, the most likely cause, is that the fuel injectors are probably not opening. The (PCM) uses the trigger signal from the crankshaft position sensor; and/or camshaft position sensor to pulse the injectors.

Does the ECU control the fuel injectors?

Electronic Control Unit (ECU) The ECU is the brain of the operation. It uses engine RPM and signals from different sensors to meter the fuel. It does this by telling the fuel injectors when and how long to fire. The ECU often controls other functions like the fuel pump and ignition timing.

What are the problems with a 1998 Honda Civic?

Why does my Honda Civic 1998 stall when I drive?

No power to the fuel-pump or the injection system…no run. So…if you have a Honda Civic 1998 doing this whole stalling while driving with no chugging (e.g. engine just shuts off), consider checking the MAIN RELAY. The part was around $50 at O’Reilly’s. I pulled the glove-box and the dash side panel, and replaced the relay myself.

How do I know what’s wrong with my civic?

The first step to figuring out what’s wrong is to pull those codes. Civics built before 2006 can display the codes on the gauge cluster through a series of flashing lights. Later model Civics will need to pull codes through an OBD2 scanner. These codes will give a good starting point towards figuring out what exactly is malfunctioning.
