micky boy Posted October 1, 2010 Share Posted October 1, 2010 You need to keep the top one (lamba sensor) bin the bottom one its no use Quote Link to post Share on other sites
lukEp Posted October 1, 2010 Share Posted October 1, 2010 The bottom sensor is just a thermal on/off switch. It's always off till the cat becomes to hot. Then it switches the light on. On the dash but because you have a de cat (no cat) it's not needed anymore just unplug it and put it in a draw and forget about it. Luke Quote Link to post Share on other sites
