AliveBoy Posted November 14, 2014 Share Posted November 14, 2014 its to differentiate between the left and right when you take them off. I'd presume they'd only fit one way wound too. Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted November 14, 2014 Share Posted November 14, 2014 Double check they are correct, as the rear sensors use a different feedback frequency, as they are purely to monitor the condition of the cats, and have no input into the O2 feedback for the ECU. 1 Quote Link to comment Share on other sites More sharing options...

Tricky-Ricky Posted November 14, 2014 Share Posted November 14, 2014 Corresponding part numbers for one and check they are indeed cat monitors and not primary O2 sensors. Quote Link to comment Share on other sites More sharing options...
