Fuel injector driver schematic

The fuel injection command pulses from the amplifier 14 are coupled to a pull-in current timer 16, a hold-in current timer 18 and an injector driver The injector driver circuit 20 is responsive to the pull-in current timer 16 and the injection command pulses to couple the unregulated voltage from an unregulated voltage source, illustrated as the vehicle battery 22, directly Cited by:  · Defective fuel injector(s) Defective injection driver circuit(s), or corrupted software; Failed or failing PCM. Note that while this is a rare event with regard to most other codes, it is often the cause of PD/PE. Despite this though, all other possible causes must be investigated and eliminated before any controller is replaced.  · This is the driver circuit I currently use for my gasoline vapor system.

This type of driver circuit uses a low resistance injector and limits current flow by controlling the gain of the driver transistor. The advantage to the current controlled driver circuit is the short time period from when the driver transistor goes on to when the injector actually opens.

If you need to replace a fuel injector, this is how to do it. Step by step, with photos. Ready for printout. Be prepared. Replacing a fuel injector seems like a daunting project, but with a little skill you can do the job yourself and save. Experts suggest that finding the best diesel fuel additive for your diesel engine depends on several factors, including your vehicle’s make and model and the type of additive. If you’re looking for a good diesel fuel additive, then use this. A clogged fuel injector is usually the result of the fuel filter not doing its job well enough, allowing particles into the fuel injectors. Clogged fuel injectors allow either too much or too little fuel into the engine, causing any number.
