Error P1166

Post by _noname_ »

Vehicle: 2000 DC2
KPRO Serial: 5915
KMANAGER Software Version: 4.1.5.0
Vehicle ECU: 37820-PND-A07 / 2062-000054
Vehicle Engine Swap: K24A2

I've recently purchased the car and the previous owner did not have a primary o2 sensor installed.
After installing a brand new Desnso - part# 234-9005 & connecting it to my conversion harness & uploading a fresh base K24A2 calibration, I'm getting error P1166 and the A/F reading does not seem to be active (displaying in red).

I've checked & double check the wiring/continuity and they are all wired correctly (according to this post: http://www.k20a.org/forum/showthread.php?t=91229).
I've checked all my fuses and all are fine (engine bay & under dash).
I've cleared the ecu and re-upload a base K24A2 map.
Without the option of testing my ecu to another working car, what else can I check?

Your best option is to test the ECU in a known working vehicle. This will save you countless hours of troubleshooting that may still not point you in the correct direction.

Finally figured it out. My problem was my female connector was bad. Once both ends were connected, the pins on the female end came loose. I basically had to push in all 4 pins once connected to get the o2 sensor to work. I've since replaced my female connector with a new one and everything is working as it should.
