How does the p0204 code on cylinder 4 work?
Engine Control Module ( ECM) checks the injectors circuit resistance and monitors the voltage drop during normal operation. The ECM will trigger the P0204 code when the resistance or voltage drop at the injector 4 is out of specifications. Need more information on how to fix the P0204 code? Need more help? What is OBDII? How does the OBDII works?
What are the symptoms of a p0204 ECM?
Symptoms may be felt before the ECM triggers the Check Engine Light. Some symptoms of P0204 include: Poor fuel economy. Rich & lean conditions. Engine misfires. Lack of engine power. Poorly running engine.
What is the diagnostic code for cylinder 4?
Cost of diagnosing the P0204 code. P0204 is a diagnostic trouble code (DTC) for “Injector Circuit Malfunction – Cylinder 4”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
What does error code p0204 mean?
P0204 Error Code Definition. The P0204 error code defines a malfunction of the cylinder four-injector circuit. Common in all OBD-II vehicles (meaning all vehicles since 1996), it can be easily mistaken for any error in the P0200-P0208 range. Even though the diagnosis process is similar, repairing this code is very different from repairing others in the same range.
What does p0204 injector circuit open mean?
After that, the current is reduced to the amount needed to hold the injector open. The code P0204 stands for Injector 4 – Circuit Malfunction. This means that the PCM had detected a malfunction in the fourth injector circuit. In other words, the PCM commanded the injector on/off but did not see the subsequent change in electrical current.
What does the code p0202 and p0302 mean?
It is P0202 and P0302 P0202 – Fuel Injector Circuit Malfunction Cylinder 2 Most likely cause a failed fuel injector or shorted wiring harness. P0302 is a misfire in cyinder #2 from the injector problem.
