I have a P0135 code on my 2004 2.7L extended cab Tacoma, which reads as malfunction in bank1 sensor1. I can see where the sensor sits ahead of the convertor on the exhaust, but the wire leads up into the floorboard through a rubber gromet. Can someone tell me where it goes and how to best access the end of the cable? Should I take off the passenger seat and somehow get under the carpet? I already have a replacement sensor that has the rubber gromet sitting on the wire between the sensor and plug.
Thanks in advance for any help!
