I just ordered a walker replacement for my front O2 sensor, I got a code 435 and decided it was time. Walker is $65.99 for the sensor with the harness and plug installed for a plug-it-in fit. Apparently the sensor is very sensitive to voltage fluctuations and resistance (which is how it works and how it tests itself). Check out the walker site (automedicsupply.com) for a good explanation of how it all works. The front sensor is part # 1271939 BTW. I'll let you know how it comes out, I'm following the instructions on Bay13.
