What does injector circuit malfunction mean?
Error Code P0200 means the PCM (powertrain control module, also known as ECM or engine control module) has detected a malfunction in the fuel injector circuit. This error code means the sensor’s performance is out of range for either the voltage or the injector circuit’s resistance.
What causes fuel injector malfunction?
Why do fuel injectors go bad? Fuel injectors will fail when debris (water, dirt particles, etc.) or rust find their way into the system and, after time, plug up the nozzle, the armature, or the nozzle needle gets stuck.
What causes fuel injector circuit open?
Here are some of the possible causes of the code: Defective fuel injector. Circuit issues, such as corroded wiring or poor connections. An issue with the PCM, such as software in need of an update.
Is there a fuse for fuel injectors?
So, the injector fuse and relay are usually located; in the relay box or power distribution center in the engine compartment. Fuses are used to protect various electrical circuits, while supplying power to components. They help the fuel pump, fuel injection and computer systems; from suffering a short circuit.
What does injector circuit high mean?
A malfunctioning electrical connector located on the fuel injector. A fuel injector that has become dirty or plugged. A fuel injector that is shorted internally and therefore causes high-voltage draws. A malfunctioning electrical harness between the PCM (Powertrain control Module) and the injector.
