No, I haven't tried running without the sensor... That's something to ponder though, as I'm going to have to remove the sensor anyway to replace a broken stud. If I do run the car minus the sensor, I'll post my results. *edit* Did a quick unplug of the O2 signal wire to the ECU while I was out cleaning my air filter. Got a CEL once the water temp warmed up enough to go into closed loop. I didn't try to drive the car, but in the past when I've gotten the O2 sensor out-of-range code it felt like the car was down on power, which makes sense. Another test might be to run only the 2nd O2 int he car, and check for codes. This post has been edited by S_C_M: Mar 14, 2004 - 10:17 PM |
