What causes the p0201 OBD-II trouble code?

What causes the P0201 code? 1 Faulty cylinder 1 injector 2 Wiring harness that has an open or short 3 Poor electrical connection in the harness or connector 4 ECM that is failing or has failed

What does p0201 mean on a PCM?

P0201 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. When the injector is switched off, the PCM expects to see a voltage that is close to battery voltage or “high”.

The on-board computer should display the message TRANSMISSION EMERGENCY PROGRAM.

When to set p0202 injector circuit open cylinder 2?

The P0202 is set if the Engine Control Module (ECM) is detects a low or high voltage drop or resistance at the injector 2. Engine Control Module ( ECM) checks the injectors circuit resistance and monitors the voltage drop during normal operation.

What does the p0202 code on the OBDII mean?

Engine Control Module ( ECM) checks the injectors circuit resistance and monitors the voltage drop during normal operation. The ECM will trigger the P0202 code when the resistance or voltage drop at the injector 2 is out of specifications. Need more information on how to fix the P0202 code? What is OBDII?
