OBDII P Code P0133, P1275

[mhall2kbox]

2000 Boxster S with less than 30k miles now displaying the check engine light. I brought it to Autozone and the following codes are being displayed. P0133 and P1275. P0133 appears to be the oxygen sensor 1, not sure about P1275... I wouldn't expect with less than 30k miles that the O2 sensor would need to be replaced.

Is this fairly common?

Can I replace the sensor myself?

thanks, mike

The complete OBD II P-code are listed for you here. Use the drop down menu to select OBD II P-codes.

P0133 Aging of Oxygen Sensor Ahead of Catalytic Converter (Cylinders 1 - 3) - Below Lower Limit

P1275 Aging of Oxygen Sensor Ahead of Catalytic Converter (Cylinders 1 - 3) - Below Lower Limit

The diagnosis of "oxygen sensor aging" helps to identify oxygen sensors that exceed emission limits because of aging.

During the diagnosis of oxygen sensor aging, the DME control module monitors the period of the sensor signal. With an old sensor, the duration of the period is too long, i.e. it is more difficult for the sensor to diffuse oxygen into the exhaust gas. Reasons for this could be frequent driving in the lower load range (city driving, short distances, etc.) or a contaminated sensor.

Bottom line - you need to replace that O2 sensor.

Thanks Loren..

Any idea how accessible this particular O2 sencor is?
