trhardy Posted March 23, 2012 Share Posted March 23, 2012 Recently posted about CEL light on; PO130 and PO133 codes. Advance Auto says "Bank 1 , Sensor 1". Got answer saying this was on the rearward exhaust manifold, which I assumed was against the firewall. Replaced sensor; light still on. Today I see a post saying "Bank 1 , Sensor 1" is on the front of the engine. Just wondering which is correct; maybe different models?? Also, do I need to disconnect battery to "reset" CEL? As always, thanks!! Tom Quote Link to comment Share on other sites More sharing options...
saman Posted March 24, 2012 Share Posted March 24, 2012 by the firewall here is the image my mistake 1130 Air/Fuel Ratio Sensor Circuit Range/Performance Malfunction (Bank 1 Sensor 1) P1133 Air/Fuel Ratio Sensor Circuit Response Malfunction (Bank 1 Sensor 1) you can remove the bat for a few min or clear it with the obd reader like i said u may of got a bad part because the first o2 sensor checks the baseline and the second checks fo see if the cat is working properly Quote Link to comment Share on other sites More sharing options...

trhardy Posted April 17, 2012 Author Share Posted April 17, 2012 sorry for delay, but I was out of town. O2 sensor back by firewall fixed problem. Not easy to get to as one of you advised. I did it without removing anything ( other than some skin and blood on right arm! ). As always, many thanks. I'm retired and can't afford to go to dealership! This is wife's '96 with 62,000 miles, so I cretainly don't want to get rid of it. Quote Link to comment Share on other sites More sharing options...
