View Full Version : Diagnostic Testing Codes?

I bought a code reader and ran KOEO, KOER, and Cylinder Balance Test.

I knew I would get some codes because smog and egr are removed and I haven't gotten a chip yet.

So here is what I got:
314 : Smog related
311 : Smog related
327 : EGR related
536 : BOO, forgot to press brake pedal
543 : Fuel Pump Secondary Circuit

90 : Cyl balance test results = PASS (I was really worried about this one for some reason, stoked it passed!)

I expected all the codes except 543. After doing some searches I found this "could" be a result of smog related codes. Has anyone else had this code, if so what fixed it. I am going to wait until spring to get a chip/tune, and I won't be driving the car except to get to the shop for the tune. So I am not too worried about it and I am hoping the tune (turn off egr / smog) will fix the 543 issue. If not, then I'll need to start diagnosing the circuit between the battery and PCM.

Suggestions???

Thanks.
