Code P0134
Hi all...
I have a 2000 Boxster S, 62000km. New MAF.
I have a CEL with code P0134. Is this a cut and dried replacement of all 4 Oxygen sensors? These are expensive...165.00 each?

Apologies...title of this post should be P0134.

P0134 is Oxygen sensor ahead of TWC (Pre-Cat) , bank 1. It is a Type 2 Fault meaning an Open circuit/no signal.

The OČ Sensors, despite a claimed service life of 100k mi. by the manufacturer can easily go south after 60k mi. but not km (notice they claim a 100k mi. service life, but do not warranty it for that mileage).

Check for a loose/damaged electrical connector, if none found, replace it.

Normally I would recommend swapping them all when one goes bad, but not @ 62k km.
