CORRECTION TO POST #3 : DTC P1133 refers to the oxygen sensor on the DRIVER side "Y" pipe in front of the catalytic converter. The sensors are interchangable left and right. Sorry for the incorrect information.
Disconnect the sensor, ignition to RUN position, engine not running. Check the vehicle harness Pink and Black wires. Pink should show battery voltage, and the black wire should show less than 5 ohms resistance to ground. Post your results.
