Hello. My name is ***** ***** I will be helping you today.Code 27 is for injectors. It should have a "subcode" showing which injector. Are you able to get that?
Customer: replied 1 year ago.
I don't have a scan tool, I just got 27 by using the key switch method. Is there a way to get the subcode that way
Expert:  Wayne Crawford replied 1 year ago.
Unfortunately not. Try ohm checking the injectors looking for 14-18 ohms. If you get any outside of spec replace them and recheck.
Customer: replied 1 year ago.
So basically use an ohm meter to test across the 2 terminals of the injector, correct ?
Expert:  Wayne Crawford replied 1 year ago.
Correct
Customer: replied 1 year ago.
And if they test OK ?
Expert:  Wayne Crawford replied 1 year ago.
I wouldnt expect them all to test good. Is there a reason you feel they will?
Customer: replied 1 year ago.
Just never had a problem with them before and there's no ryme or reason to when it acts up. Can go a couple days without or will do it off and on all day.
Expert:  Wayne Crawford replied 1 year ago.
Well then your next step is to trace all of the control wires back to the PCM looking for a bad spot shorting out. That may be the case with yours since its so intermittent.
