B-R-T Posted February 23, 2008 Share Posted February 23, 2008 P0135 - Oxygen sensor 1, bank 1, heater control - circuit malfunction. I suggest to check fuse, wiring, and then sensor. If everything is OK - malfunction in ECU. Chocking could be caused by ECU making mixture way too ritch because of the malfunctioning oxygen sensor heater.
