Brighton99v Posted May 7, 2009 Share Posted May 7, 2009 so i got dtc 1133; o2 sensor heater circut high input. i bought a universal fit o2 sensor from advanced auto parts and installed it. no change! still reads the same code! what could be the issue here? i hooked up the wires corectly. Only, there are 2 black wires(oe) connected to 2 white wires(new part) the schematic says the 2 white wire are the heater wires. the other 2 wires are definately hooked up right. what should i try next? i need an inspection sticker:spin: any one have any bright ideas?

Bdubs Posted May 7, 2009 Share Posted May 7, 2009 Just wondering, did you clear the code with a scantool, or by unplugging the negative terminal? Perhaps you fixed it, but the code is still stored in there. I'm being optimistic, thinking that may be your problem. Link to comment Share on other sites More sharing options...
Brighton99v Posted May 7, 2009 Author Share Posted May 7, 2009 not only did i start off with a disconnected neg battery terminal, but i also cleared the codes when done with the install with a MODIS 8.2 Snap-On scan-tool/diagnostic computer.

eekay Posted May 8, 2009 Share Posted May 8, 2009 Any sort of aftermarket exhaust on there? Is the O2 sensor too close to the manifold/header? My 9.3 cups EJ22 makes me feel like my **** is 2.8 decimeters! Link to comment Share on other sites More sharing options...
