Post subject:  What codes with Weeks stage 1 & 2

Quick question. As I noted in my other thread I installed the weeks stage 1 & 2 kit on the Jeep. Wondering what codes I should be getting now. I have -

P1140 Vacuum reservoir circuit (short/ground/open)
P0403 EGR circuit (excessive volt/open circuit)
P0101 MAF sensor signal (negative/positive deviation)


I was fully expecting the P0403 and possibly the P0101. But I was not expecting the P1140. Should I be seeing these codes?

Thanks.

P1140 is actually bad/missing FCV on this vehicle. So that makes sense.

Is your MAF still unplugged?

You will need a tune to get rid of the other two codes. Either GDE or one of the DIY tunes.

No. MAF is plugged in.

This is correct.

Looks normal for a non-tuned ECU.
