Steve W Posted July 5, 2002 Share Posted July 5, 2002 I think (but, wait for back-up) the upper/1st/top one is Oxy/Lambda, and the lower/2nd/bottom one is temp - ON A J'SPEC ! ! [ I believe, on a UK, they are BOTH Oxy/Lambda sensors ? } BUT, WAIT FOR THE 'BIG-BOYS' REPLIES ! ! Quote Link to comment Share on other sites More sharing options...
Ian C Posted July 5, 2002 Share Posted July 5, 2002 Upper one is the O2 senser. The lower one is the CAT. You can also tell by the sensor component: CAT temp sensor is just a 1/4" rod O2 sensor is a lot thicker and ventilated And the wiring: CAT temp sensor has only one wire O2 sensor has four -Ian Quote Link to comment Share on other sites More sharing options...
