Was about to look into replacing my 02 sensors from oxygensensors.com and later that day I get the following error codes

P1276 (manuf. control. Fuel air metering)

P0153 (slow response Bank 2 sensor 1)

I can't find any info on 1276 at all.

any assistance before I replace the parts would be appreciated!

2000 Boxster S 40K miles.

p.s.

does the Bentley manual have info on this. I ordered that thing months ago from Amazon and they keep delaying...

Your second code sounds like an "aging" sensor which I understand does not light up the CEL but is still defective in that the aging sensor reacts more slowly than it should and sends "delayed" info to the computer.

The correct O2 sensor for the earlier Boxsters (not sure if it covers MY2000) is Bosch part number 13806 and costs about $148 on oxygensensors.com, with free shipping. When you remove the original part from the car, you will see the Porsche Part number AND the Bosch Part Number stamped on the side of the sensor.

There is someone on eBay selling what they call "same as OEM" O2 sensor for Porsche for $98 plus shipping. They state that the connectors are the same as OEM and that no cutting of wires or splicing is necessary.

Regards, 1schoir.

P.S. I have same problem with Amazon.com and the Bentley manual, although they advertised that it was "available". Can't beat the price, though.

P1276 Signal Delay Time for Oxygen Sensor Ageing, Bank 2 – Above/Below Limit

P0153 Signal Period for Oxygen Sensor Ageing, Bank 2 – Above/Below Limit

Potential causes:

– Oxygen sensor ahead of TWC

– Wiring (oxygen sensors exchanged)

– Leak ahead of TWC or in the area of the oxygen sensor after TWC

If the wiring/connectors are good - it does look like a sensor.
