What are the symptoms of a failing ICP sensor?

Common signs include starting issues, engine misfires, the Check Engine Light coming on, and a decrease in power, acceleration, and fuel economy.

What does an ICP sensor do?

The ICP or Injector Control Pressure sensor is an essential part of your Ford Diesel engine. This electronic part communicates how much pressure is needed to determine the amount of fuel to deliver to the motor.

What should ICP voltage be at idle?

The ICP voltage is very important. You should see 0.2 – 0.25 volts Key On Engine Off (KOEO), and when you start cranking the voltage should climb up to around 4.5 volts if the engine doesn’t start. The injectors will not be pulsed until this voltage gets to 0.8 volts.

What temp should a 7.3 run?


What is normal fuel injection pressure?

It is between 35 and 65 pounds per square inch (psi) on most vehicles.

What is normal diesel injection pressure?

But unlike fuel-injected gas engines that inject fuel at 10-60 psi, diesel fuel-injection systems run in the 10,000-30,000-psi range.

What voltage is 7.3 IDM?

Injector Power & Ground

The voltage supplied to the injectors is 115 volts DC and is only activated when one of the injectors is firing.

What is the pressure of fuel injection pump?

The components serve distinct functions: the pump pressurizes the fuel from about 3-4 bar (40-60 psi) to between 100-300 bar (1500-4500 psi). The fuel injectors spray the fuel directly into the cylinders.

What happens if fuel pump pressure is too high?

High fuel pressure will make an engine run rich, while low fuel pressure will make an engine run lean or not at all. Fuel pressure readings that are higher than manufacturers specifications are generally caused by a problem in the return line fuel components.

What are the symptoms of a failing high pressure fuel pump?

Symptoms of a high-pressure fuel pump failure are:
  • Delayed start of the engine.
  • Hesitation or sputtering in acceleration between 2000 RPM to 4000 RPM.
  • High engine temperatures.
  • Vehicle stalling due to exertion or temperature.
  • Fuel pressure gauge reading low measurements.
  • Poor gas mileage.

How do I know if my injection timing is correct?

Injection timing is checked by measuring the injection pump plunger’s stroke at TDC with a dial indicator. Adjustment, if necessary, is based on this measurement. Before adjusting injection pump timing, the cold start cable must be all the way in, and the camshaft drive belt must be properly installed and tensioned.

How do you tell if timing is slightly off?

What happens if timing is not advanced enough?

If the spark timing is initiated too early, the cylinder may experience detonation and potentially cause damage. If the spark occurs too late, the engine runs flat, makes less power, and may overheat.

What are the symptoms of advanced timing?

  • Engine knock. One of the earliest symptoms of a problem with the automatic timing advance unit is engine knock.
  • Sluggish performance. Another symptom of a problem with the automatic timing advance unit is sluggish engine performance.
  • Excessive black smoke.

What will retarding timing do?

Retarding the timing means the plug fires later in the compression stroke (closer to TDC). Retarding the timing can help reduce Detonation. However, if the spark happens too late, you will lose power.

What happens if you advance timing too much?

Overly advanced timing will reduce power and make the engine overheat, and also can cause detonation which starts a vicious circle, the detonation overheats the engine and the overheated engine promotes detonation, often leading to a hole melted in the piston.
