Lambda sensor on a 2004 Ford Focus
I have a fault with Bank 1 sensor 1 (lambda sensor), which I believe is the pre-cat sensor. Which one is this as I can see two sensors by the exhaust manifold sitting side by side?

There should be one lambda sensor on the manifold and another one on the exhaust pipe itself. Should not be two on the manifold. Suggest you re-check.
