whats up with the o2 sensor on the crx's. Is is just me? I keep checking the ecu when the cel comes on, and all i get is a code 1. I replaced the sensor with a new one, the light went off for a while. Then the next day it was back. the connection is good. I even removed the plastic connectors that click together and crimped the wires directly together. but still keep getting that annoying check engine light. Is there something else that would be causing this code?

 

i had the same problem. it was so annoying that i was almost suicidal. https://honda-tech.com/zerothread?id=1325377 check the thermostat ground, there should be 2 next to each other. make sure they are separate, tight, and clean. that was my problem.

 

i'll check it out tonight.
