What causes the p0203 code on cylinder 3?
Engine Control Module ( ECM) checks the injectors circuit resistance and monitors the voltage drop during normal operation. The ECM will trigger the P0203 code when the resistance or voltage drop at the injector 3 is out of specifications.
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 the p0203 code on the ECM mean?
What the P0203 code means. 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.
How much does it cost to repair a car p0203?
The auto repair labor rates vary widely across the country, and even within the same city. Most auto repairs shops charge between $75 and $150 per hour. When is the P0203 code detected? The P0203 is set if the Engine Control Module (ECM) is detects a low or high voltage drop or resistance at the injector 3.
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.
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.
How to troubleshoot a p0203 circuit malfunction?
The following steps will help you troubleshoot a P0203 code: Perform a visual inspection of the injectors and connections. Many problems can easily be found in the harness and connectors. So, begin your diagnosis by visually inspecting the sensor and its connection. First, check for other codes that would indicate cylinder misfire (P0301 – P0308).
What the P0203 code means. 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.
