What does the engine control module code p0204 mean?
What does the engine control module code p0204 mean?
What the P0204 code means. The Engine Control Module (ECM) runs checks on all systems at startup, and many times a second while the vehicle is running. P0204 tells technicians a malfunction was found for cylinder 4 injector circuit. This code is similar to P0200 – P0203, and P0205 – P02012.
What causes a p0203 engine light code to appear?
The causes of a P0203 engine light code could be any of the following: Bad injector. This is usually the cause of this code but doesn’t rule out the possibility of one of the other causes Open in the wiring to the injector Short in the wiring to the injector First, using a DVOM check the resistance of the injector.
What does it mean when PCM says p0203?
Although generic, the specific repair steps may vary depending on make/model. P0203 means that the PCM detected a fault in the injector or the wiring to the injector. It monitors the injector and when the injector is activated, the PCM expects to see the voltage pulled “low” or close to zero.
How to troubleshoot a p0204 injector malfunction?
The following steps will help you troubleshoot a P0204 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 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.
Is there a problem with the Dodge Caravan p0303?
P0303 should not be ignored, and can be a threat to the drivability the Dodge Caravan. The nice thing about P0303 is that it’s a cylinder specific trouble code, which makes diagnosing the problems simpler than P0300, which means that the cylinders are randomly misfiring.
Why is there an error code p0203 on cylinder 3?
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. The PCM also works by monitoring the resistance circuit, and sets the code if it’s too high or too low.
What does the misfire code p0303 mean?
P0303 is a cylinder specific misfire code, which means that Cylinder 3 is misfiring and causing the code. An important thing to understand when finding the location of cylinder 3 is that it’s going to be the 3’rd cylinder in the firing order of the vehicle, and not the 3’rd cylinder that you might see when looking at the engine.
