I decided to convert my single wired 02 sensors to heated one and now I have an SES Light.

Datamaster shows Err#26: QDM3 CCP Electrical Fault

Is anyone fimiliar with this DTC? I'm wondering if this is coinsidence after the 02 conversion???

I used AC Delco 3 wire 02s, good ground and use a Key-On power source from the Air Pump Relay.

Anyone have any ideas? Check out these Fuel counts from logging!

LTerms: 160/145
STerms: 206/132
(Fuel Trim Cell:16)

I have a feeling it's due to the new 02 conversion. But need to know why. They heat up just fine. Is it possible to overheat 02 sensors???

Thanks for looking.

Note: Also just put in Accel 24# with no tuning to compensate for them yet. But no SES light after the injectors, just after the 02 swap... doubt it would have cause a SES, just a note.

 

TTT Please.
