P0135 code and battery drain 96 accord EX 2.2
I have P0135 code on Honda Accord 96 EX 2.2L. The o2 sensor gives proper resistance and it was changed a year ago. I am not able to find wiring fault as dont have wiring diagram. Same time Battery is draining too. Are these two connected? Will battery drain if there is short in the wires of o2 sensor heater circuit? How to fix it?
Thanks
Thanks

Should be unrelated, power for heated O2 sensor is supplied by the PGM-FI Main Relay, [fuel injector relay] that would be off if ign. switch is off, you have a parasitic drain, test and trace like this... https://honda-tech.com/forums/showth...tic+drain+test 94
