Hi All, I have a 2000 Boxster S with 43,000 kms. Went for a drive the other day when the check engine light came on. Durametric software shows fault code:

Current Fault Codes

P0154:
Porsche fault code 18 - O2 sensor ahead of cat. conv. Cylinder (4-6)

Is this code indicating that the 02 sensor before the CAT should be replaced on the drivers side? The one closet to the muffler?

Is this the correct part?

Thanks in advance.
