We’ll aim only on port fuel injection devices that use the electric pump to crank out each of the tension while in the procedure, but most of this facts may also implement towards the fuel shipping technique of immediate-injection engines, also.
The pc screens the fuel tension and adjusts the pump’s Procedure to make sure that the motor is acquiring the proper quantity of fuel.
If strain would not maximize if the duty cycle is commanded large, possibly via a scan Instrument or at broad-open up-throttle with a check drive, This might suggest a defective pump.
