First Cel Need Help
OK...so i'm driving around the other day going about 40 and the CEL light comes on. I swing by jonny's later on to use his OBD scanner. The code is a P1055 i think. "O2 Sensor malfunction heater circuit bank 2 sensor 1" any clues on how to fix it? We reset the code and it came back on within 2 hours. I'm not familiar with the emissions on a GS. I'm thinking the sensor is probably ok, but I dont know what the heater circuit is?

If you've replaced the sensors recently, I'd check the connector to be sure no smashed pins.

Well thanks to jonny (dx3) i found out sensor 1 is the one closest to the engine, bank 2 is the one NOT connected to Cylinder 1. I didnt see a fuse in the schematic. It basically told me three things. ECU, 02 Sensor, Wiring between ECU, Main Relay, Sensor. So i'm off to mess with the connector, do an ecu reset and see if that works. If not I'm gonna break out the ohmeter and check the sensor itself.
