HPT scanner is showing the upstream o2 sensor at 0, even with the o2 disconnected. we've tried 2 different sensors, 2 ECU's, and rang out the harness wiring. everything looks good. all DTC's are enabled.

this is on an '02 Z24 that we've swapped an Eco into. the harness is only missing the ABS stuff.

any thoughts?



If I'm weird and everyone else is weird, does that make me normal?

using the hpt scanner these are the dtc's we are getting

also we just tried to flash the ecu again and we are getting a error when it tried to pull the veichle info sawing wither the car isn't in run or the cable isn't plugged in.

also both the ecu's we have used were out of auto ecos and we are flashing it with a 5speed eco tune. could this have some issues also?
