The wiring on my primary o2 sensor is bad or something and it's gettting voltage irregularites. I'm getting a CEL code 61 and wonder if it's going to make me run rich or anything. The car seems to run fine and I don't get any other codes. Its too cold outside to be messing around with my car so i was wondering if it would cause any problems if i left it this way. I can fix it by messing with the o2 plug wiring and then resetting the ecu, but after a month or two the code would come back up.

My 1997 dx has the same problem, cel61 after running for a few days after resesting ecu and cel coming back. Should i do a wire trace? Sensors are new and plugs are good shape........

 

did you replace the oxygen sensor, you should get a denso 02 sensor

 

Sensors are new and plugs are good shape........

Yes, sensors were replaced......

 

just gotta inspect the wiring from the ecu to the sensor. The problem isnt gonna fix itself. You know what you need to do...
