What makes a fuel injector trigger a p0202 code?
Common Problems That Trigger the P0202 Code. Malfunction of the Fuel Injector. Malfunction of the PCM Fuel Injector driver circuit. Defective wiring/connections in the Fuel Injector wiring harness. Defective Fuel Injector power circuit(s)
Where is the P0420 OBD2 trouble code stored?
The front O2 sensor measures the mixture, and it tells the engine control unit if the engine is running with a rich or lean mixture and adjusts it. The rear O2 sensor is just a diagnostic O2 sensor for this trouble code. If the rear O2 sensor is getting faulty values, the p0420 code will get stored in the engine control unit.
How can I fix the P0420 code on my catalytic converter?
To fix the P0420 code, you need to diagnose what is causing the trouble code. Start with inspecting and diagnosing your catalytic converter and continue with checking the O2 sensors. What can cause a P0420 code? A bad catalytic converter is the most common cause of the p0420 code.
What causes the O2 sensor to show the code po420?
Rich or lean mixtures can damage the catalytic converter, and when the catalytic converter is damaged/filled with fuel, the efficiency will be low, and the rear O2 sensor will see that and show the trigger the code Po420.
Common Problems That Trigger the P0202 Code. Malfunction of the Fuel Injector. Malfunction of the PCM Fuel Injector driver circuit. Defective wiring/connections in the Fuel Injector wiring harness. Defective Fuel Injector power circuit(s)
What does the p0202 OBD-II Diagnostic Code mean?
The P0202 code is a general OBD-II diagnostic trouble code (DTC) associated with the injector circuit. Note: This code may be seen with P0200, P0201, or P0203-P0212. P0202 may also be seen with misfire codes and lean or rich condition codes. What the P0202 code means
What happens if you leave p0202 in failsafe mode?
P0202 can present serious issues if left unresolved, such as the vehicle dying and not being able to restart. This can be a result of the ECM enabling failsafe mode to protect the vehicle or a failed component, such as a fuel injector.
What to do if OBD-II cylinder 1 injector does not work?
If you have access to an injector tester, activate the injector and see if it operates. If the injector operates, then you likely have either an open in the wiring, or a blocked injector. If you do not have access to a tester, swap the injector with another one and see if the code changes. If the code changes, then change the injector.
