hey guys im getting codes 1 and 41 both for o2 sensor heater and im converted to obd1 with a jumper harness and i would like to know what obd1 pins are the o2 sensor please and thank you in advance

 

It's been a while since I was really into Hondas, and back in the day I could of told you exactly what pin you needed. But what I do know is most jumper harnesses (rywire, xenocron etc..) have the wires already prepped for you to do a 4wire o2 sensor. And the instructions will tell you what wires from the jumper go to what on the o2 sensor. Is the car running okay? Because if so you I'd just live with the check engine light. If its running shity and you're running chipped obd1 you can always turn off closed loop. And that Should smooth things out once it's warm. While its cold it'll still idle rough but it will warm up and run great.

 

O2 signal is located at d14
And heater control is at a6

 

well im using a jumper harness but im getting codes 1 and 41 and wanna make sure its not a rywire jumper harness so i dont know if its exact. so if anyone can tell me the exact pins on an obd1 harness

 

 

THANK YOUUU

 

Note that if wires at the ECU are already at those locations tap them don't remove and replace
