The engine computer (PCM) controls the signal to the fuel injectors in groups of two. If the PCM detects one or both of the fuel injectors in that group are not functioning properly, the PCM will set code P2153. Fuel injection system is a mechatronic circuits that combine mechanical and electronic circuits to achieve a common goal, that is to supply fuel to the intake manifold with ideal volume. There are two groups in the fuel injection system, namely fuel lines group (mechanical parts) and controller group (electronic parts).352 Sensor Supply 1 Circuit - Voltage Below Normal or Shorted to Low Source 386 Sensor Supply 1 Circuit - Voltage Above Normal or Shorted to High Source 415 Engine Oil Rifle Pressure - Data Valid But Below Normal Operational Range - Most Severe Level 418 Water-in-Fuel Indicator - Data Valid But Above Normal Operational Range - Least Severe LevelUnplug the electrical connector from the fuel injector you want to test. Turn the ignition switch to the ON position. Touch the terminals (one at a time) of the harness connector with the test light. One of the terminals should make the test light glow, this is the injector power source coming from the computer. The basic D Jetronic system employs a recirculating fuel system in which a constant supply of fuel is pumped from the tank and delivered through a fine filter to the injectors at constant gauge pressure (usually around 2 Bar / 30 p.s.i.). A spring loaded regulator valve (2 on the V12) spills off the excess fuel which returns to the fuel tank.Check engine light on with this code: P2149-FUEL INJECTOR GROUP 2 SUPPLY VOLTAGE CIRCUIT I have an Edge w/ Attitude monitor.

The fact that the fuel injectors’ harnesses are routed in close proximity to extreme temperatures should be noted. Jan 07, 2020 · Injector pulse width is the amount of time, measured in milliseconds (ms), that a fuel injector stays open (delivers fuel) during a cylinder intake cycle.
