Re: SES code 1133 need help ??????????? If you have not changed anything recently that may have damaged wireing or any connections, that code means that your Drivers side front O2 sensor has gone bad and needs to be replaced. Before replaceing the sensor check: Wiring, exhaust leaks within 6-10" of the sensor, and make sure you didn't use any silicone which may have contaminated the sensor.
