What does the code p0203 mean on an injector?
After that, the current is reduced to the amount needed to hold the injector open. The code P0203 stands for Injector 3 – Circuit Malfunction. This means that the PCM had detected a malfunction in the third injector circuit. In other words, the PCM commanded the injector on/off but did not see the subsequent change in electrical current.
What does error code p0203 mean on a Honda Accord?
Error Code P0203 is defined as Cylinder 3 Injector Circuit Malfunction. This code means the PCM (powertrain control module, also known as ECM or engine control) has detected a problem in the injector or its wiring, or in injector circuit for cylinder 3.
What does p0203 stand for in PCM?
The code P0203 stands for Injector 3 – Circuit Malfunction. This means that the PCM had detected a malfunction in the third injector circuit.
What are the causes of code p0203 in Windows 10?
To sum things up, the common causes for code P0203 are as follows: 1 Failed injector. 2 Fault in the injector circuit. 3 Problem with the PCM (injector driver).
What does p0203 mean on an injector?
P0203 is a diagnostic trouble code (DTC) for “Injector Circuit Malfunction – Cylinder 3”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
Error Code P0203 is defined as Cylinder 3 Injector Circuit Malfunction. This code means the PCM (powertrain control module, also known as ECM or engine control) has detected a problem in the injector or its wiring, or in injector circuit for cylinder 3.
When to set the p0203 diagnostic trouble code?
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. The ECM looks for a specific range of voltage and resistance from each injector circuit and when the results are found to be out-of-range, a diagnostic trouble code (DTC) will be set.
What is the error code for cylinder 3 injector?
When the injector is switched off, the PCM expects to see a voltage close to battery voltage or “high”. If it doesn’t see what it expects to see, it detects a low or high voltage drop or resistance at injector 3, which activates the Error Code P0203.
