In a fuel injection system, it’s important that the computer has information concerning the amount of fuel pressure in the rail at all times. This information is necessary for the computer to determine the actual injector timing, the width of each pulse, and the pressure required during operation. In some diesel engines (notably many Ford engines), this job is done by the injector control pressure sensor or ICP. The sensor works on the basis of capacitance and feeds an analogue voltage signal to the vehicle’s computer that tells it how much pressure is in the rail. Like all other sensors, the injector control pressure sensor is subject to wear and tear and eventual failure through normal use. If it fails, the computer will be unable to determine the pressure in the rail, which will adversely affect the operation of the engine.
The vehicle is lifted and supported on jack stands The defective injector control pressure sensor is removed The new injector control pressure sensor is installed The new sensor is checked for proper operation and the jack stands removed The engine is run and the vehicle is road tested for proper operation
Without an operational ICP, your vehicle’s computer will be unable to operate the fuel injection system correctly. This can result in a number of problems, ranging from lean or rich operation to the Check Engine light turning on. Have a faulty sensor inspected immediately.
Your vehicle’s computer needs to be able to determine the pressure in the rail at all times. If the ICP fails, expect erroneous engine operation, rough idling, and the Check Engine light to turn on. Have this issue diagnosed immediately. Remember – fuel system work is never something that should be undertaken on your own. Always leave it to our expert mechanics with the proper work area, experience and safety equipment.
