Have you checked the fuses for the heater? Get your wiring diagrams from the resources section of this forum. See the blue ribbon at the top of your screen. UK diagrams on page 1 and NA diagrams on page 2. They are build date dependent.

Post-Cat sensors = Lambda monitor sensors, both banks are the same, part number 11781433940.

• Replace them in pairs
• Bosch are the preferred make
• Do not buy Universal fitting O2 sensors, the connection box is a real pain to deal with.

I changed all my sensors for bosch don't buy cheap universal the mistake I made was mixing up bank1 with bank 2 change one at a time bank one is behind the engine next to bank 2
Hope this helps
