What causes a p0202 engine light code to appear?
The causes of a P0202 engine light code could be any of the following: Bad injector. Open in the wiring to the injector Short in the wiring to the injector Bad PCM
What should I do if my injector does not work?
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. At the PCM, remove the driver wire from the PCM connector and Ground the wire.
How to check for fuel injector trouble code?
Open in the wiring to the injector Short in the wiring to the injector 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 p0202 mean on a PCM?
P0202 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.
