What Sends Signal To Injectors? The (PCM) uses the trigger signal from the crankshaft position sensor; and/or camshaft position sensor to pulse the injectors. What triggers fuel injection? The process is: The fuel pump pushes petrol or diesel through the fuel lines to the injectors. The ECU (engine control unit) uses sensors to work out
What Would Cause Injectors Not To Fire? So, the most likely cause, is that the fuel injectors are probably not opening. The (PCM) uses the trigger signal from the crankshaft position sensor; and/or camshaft position sensor to pulse the injectors. How are fuel injectors triggered? The Injector It is supplied with pressurized fuel by the
What Controls The Injector Pulse? The (PCM) uses the trigger signal from the crankshaft position sensor; and/or camshaft position sensor to pulse the injectors. What causes no fuel injector pulse? When these fuses blow, the system they support stops working, and the engine stops running. As a result, there is no injector pulse while craking.
What Can Cause A P0203 Code? If the injector is fine, the P0203 OBD2 code is most likely caused by faulty wiring or poor electrical connection. The fuel injector utilizes power to deliver the fuel. Any wiring problems will cause the injector to operate poorly, hence affecting engine performance. What does fault code P0203 mean?
