swapping a b16a2 into a 92si civic hatchback using a obdII gsr engine harness with a rechipped p28. I keep getting a code 1 which is primary o2 sensor. The code is thrown right away right when the engine is on if that helps. Thanks!

 

do you have the sensor plugged into the primary plug on the OBDII harness?
do you know for sure the sensor is good?maybe try another sensor.also try probing the wires to make sure they go to the correct ECU pins with no breaks or shorts.

the engine harness only has one 02 sensor plug, the primary one. the secondary 02 sensor goes straight to the cabin.

i would try the same steps though: make sure the sensor is securly plugged in. then i would check each individual wire with a multi meter. don't forget to reset the ecu between each step to see if the code is erased.
