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.
What are the input signals in a pulse injector?
These are the Ne, G, and IGf signals. Inside the ECU, the Ne Signal is used to produce an injection chive signal. The G signal is used to determine the timing of the injection signals. The IGf signal is monitored for fuel delivery fail-safe. (With Conventional EFI, the IG signal is used to produce the injection drive signal.)
Why is the OBD II scanner not communicating?
Check the fuse box (Power Panel), it might be the reason why PCM isn’t able to receive power as well as communicate.
Why is my N16 Pulsar engine not working?
If you have fuel pressure and hear ticking your injectors are fine and working. Crank angle sensors tell the ECU where the crankshaft is in relation to everything, so it controls the spark and injector pulse. No sensor means no spark or injector pulse, therefore no engine……..
How to check for fuel injector trouble code?
First, using a DVOM check the resistance of the injector. If it isn’t within specs, then replace the injector. Check for voltage at the fuel injector connector.
What does p0205 mean on a cylinder 5 injector?
Although generic, the specific repair steps may vary depending on make/model. P0205 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.
What does trouble code p0203 on OBD-2 mean?
What does that mean? This diagnostic trouble code (DTC) is a generic powertrain code, which means that it applies to OBD-II equipped vehicles. 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.
When does the p0205 injector circuit malfunction?
Engine Control Module ( ECM) checks the injectors circuit resistance and monitors the voltage drop during normal operation. The ECM will trigger the P0205 code when the resistance or voltage drop at the injector 5 is out of specifications. Need more information on how to fix the P0205 code?
What does a faulty fuel injector code mean?
Some of them include: faulty fuel injector, loose or corroded fuel injector connector, dirty fuel injector supplying the number one cylinder, plugged fuel injector, and open or short in the fuel injector harness etc. You must be curious to understand what this particular code indicates.
What is the DTC for injector circuit malfunction?
P0205 is a diagnostic trouble code (DTC) for “Injector Circuit Malfunction – Cylinder 5”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic for $0.0 .
