Angry Cel!!! P0133? Front O2 sensor...

Dammit, first Cel in any car I have ever owned

Oh, well,
anyone out there have experience with P0133? Through reading the cel list here at nasioc, it appears to be the front o2 sensor, but would like to check all connections around front sensor before buying new parts or taking to subaru.

any ideas, experience or comments?

thanks

P0133 - HO2S Sensor Circuit Slow Response

The HEGO Monitor checks the HO2S Sensor frequency and amplitude. If during testing the frequency and amplitude were to fall below a calibrated limit, the test will fail.

Causes
Contaminated HO2S sensor.
Exhaust leaks.
Shorted /open wiring.
Improper fueling.
MAF sensor.
Deteriorating HO2S sensor.
Inlet air leaks.

Access HO2S test results from the Generic OBD-II menu to verify DTC

Diagnostic Trouble Code.

If you have more than the basic scanner you can see the values of the failed test and see if it was a gross failure or just a little out.
