    AJQ engine and lambda sensors.... 1 or 2?

    All

    Got a lambda sensor error code on my 180bhp AJQ engined 1.8TQS, but is there only a pre-cat sensor on this engine, or could it also have a post cat one as well.

    I think early cars only had the pre-cat. Can anyone confirm this?

    Cheers
    Jason.

    Don't want to buy the wrong one as I'm gettin some lean running at higher revs and burnt out a set of plugs. Ars3.

    AJQ has two sensors.

    Pre cat, wideband for fueling and a post cat for emmisions (measures how well the cat is doing it's job).

    Oh

    is this conflicting? Or are we saying that before 2003 the AJQ has 1 and post 2003 it has the 2???

    Sorry to ask the same question after you two went to the trouble of answering

    Cheers
    Jason
