I have a 00 GSR swap (obdII) with a OBDI ECU and a fields vtec controller. The car runs fine.... First, i have no o2 sensor YET. But the weird thing is its throwing Code 6 which I believe is a coolant temp sensor code. But why is that the only code its throwing when I dont even have an o2 sensor hooked up? All I can think of is a pin might be crossed somewhere in the harness? Any other ideas? Thanks.

get o2 sensor in and see if it still does it.

I had the same issue the other day with my car only throwing a code 21 when i had mothing hooked to the vtec solinoid, when i hooked up the solinoid, then i started throwinh a code for the pressure switch, but not till after i hooked up the solinoid? weird obd1 stuff?
