for the second time now my o2 sensor off the exhaust manifold is throwing 2 cels. i just replaced it and its giving me the same errors not even 30 minutes or 10 miles after replacement, which is an o2 malfunction and an o2 heat error? i forget the actual code numbers now, i think they are 141 and 132 off the top of my head. its also a standard obd2 system. any thoughts?

 

perhaps bad wiring on the wiring harness before the O2 sensor

 

ok, so where could i obtain a new o2 clip from? dealer dosent sell it because its part of the main harness

 

also, did you torque it down correctly to the exhaust?

 

You'll prolly have to cut the wiring harness off there and solder on some new wiring for it. Do NOT splice the wires, solder them.

 

i left it snug but not over torqued if thats what your asking

soldering is always better! laugh.gif

 

according to my book.. between 37 and 44 pounds of torque to properly torque the O2 sensors.

 

hm... well i don't have an adjustible wrench so i not sure of the final torque but, over torquing it could cause a problem you think?

 

yes... as can dropping them. They are rather fragile, believe it or not.
