What does fault code P0203 mean?

What does fault code P0203 mean?

The P0203 is a diagnostic trouble code that is set when the engine control module (ECM) has detected a fault in the injector circuit for cylinder 3.

What does open circuit mean on a injector?

If you are talking about car fuel injectors then it means just that – that the electrical circuit is “open” and not closed, meaning electrons will not flow. Either a lead wire or the injector coil itself is broken, though there can be other reasons.

How much is it to replace fuel injectors?

Replacing a Fuel Injector is definitely not cheap. It will differ quite a bit based on where you live, what brand you want to use and where you install it. But you can expect to pay up to $350. The parts themselves are up to $200 at most, so the rest will be installation and labor related to this process.

What causes an open circuit on a fuel injector?

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.

What can cause injectors to stay open?

The injector would stay open if the ground wire were grounded all the time. The injector would stay open if the ground wire were grounded all the time.

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 injector circuit low?

A weak or damaged internal return spring may be present in the number 2 fuel injector. The number 2 fuel injector could be faulty. The wiring or connector associated with the fuel injector on the number 2 cylinder could be damaged. The powertrain control module could be malfunctioning.

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.
