The P0133 is usually a bad front o2 sensor the one screwed into the exhaust manifold.I posted the info on that code. When you start the car when it's cold pay attention and see if you can hear the air injection pump turn on then turn off in like 30 seconds. Let me know what you find.
Possible causes of DTC P0133:
* An intermittent connection or corrosion in the O2S-1 harness connector can set this DTC. Use Scan tool to monitor O2S-1 voltage with engine running at normal operating temperature while wiggling the signal and ground wire. Make sure the sensor is tight.
* The most probable cause for DTC P0133 is contamination. Check for obvious contamination (oil, fuel or engine coolant) by removing sensor. Identify and correct the cause of the contamination if contaminated. Replace the O2S-1.
