I bought a 94 Civic CX with a DX motor. Now the check engine light comes on. After checking the code it came out 10 (IAT Senor). I checked the IAT Sensor closely and noticed that the previous owner had put a 4 wire O2 sensor on and one of the wires are spliced into IAT Sensor wire. Does anyone know if this connection is correct? Can someone tell me exactly how to wire the 4 wire O2 sensor. Hope this makes sense! Please Help Me!!!!!!!!!!!!!!!!!!
