I'm pasting this directly from the site of origin. I have an 06, auto and it has thrown that code everytime it rains during the cooler months. The CEL comes on and will stay on for 10 or so starts and then go off on it's own. I have yet to replace the sensor and it has been doing this for 3 years now. I do detect a slight exhaust leak (notorious with the 06) and that is probably the cause of mine. The computer will not store the code so it will not have an impact on emissions inspections unless the light is on when you take it to be tested.
What does that mean?
This involves the front oxygen sensor on Bank 1. This code indicates the engine air fuel ratio is not being adjusted by the oxygen sensor signal or the ECM as expected to do so, or not adjusted as often as expected to do so once the engine is warmed or under normal engine use.
You will likely not notice any drivability problems, although there may be symptoms.
code P0133 may mean that one or more of the following has happened:
The oxygen sensor is faulty
The wiring to the sensor is broken / frayed
There is an exhaust leak
Possible SolutionsThe simplest thing to do is to reset the code and see if it comes back.
If the code comes back, the problem is more than likely the front Bank 1 oxygen sensor. You will likely wind up replacing it but you should also consider these possible solutions:
Check and fix any exhaust leaks
Check for wiring problems (shorted, frayed wires)
Check the frequency and amplitude of the oxygen sensor (advanced)
Check for a deteriorating / contaminated oxygen sensor, replace if necessary
Check for inlet air leaks
Check the MAF sensor for proper operation
