hey all, i swapped a sohc vtec ZC into my 94 civic vx hatch, and have a P70 running it. I keep getting a code 1 (heated o2 sensor), but there isn't a heated o2 in any (that im aware of) JDM 92- 95 civics. The ZC came with a 1-wire o2, i have since replaced it twice with a CX (1 wire) o2 sensor, pinned directly to D14 on the ecu. It still pops the code everytime, even after resetting the ECU. Can someone please tell me what the hell is going on? after 6 months and various posts on various forums, i have had no one reply with any helpful advice other than "there's no such thing as a sohc vtec zc". If anyone has a SOHC VTEC ZC, PLEASE post and let me know which ECU and what wire o2 sensor you are running. Thank you.
