    Sensor info wanted (2.2 engine)

    I have 3 sensor faults showing up on my Sri 2.2. I would like to know how to locate them and what they look like if possable and maybe prices for the parts. Here are the sensor faults on my 2.2 engine..

    Map sensor
    Throttle sensor
    Exhaust sensor (I think)

    It was on the Tech 2 system at Vauxhall yesterday and they want it back in again on Monday for more tests. They said they need to check all the wiring as 1 sensor fault could be making the other 2 sensors not work. Thanks

    MAP is on the air intake tube (see the plug going into the pipe from the airbox?) i'd go to a wreckers and grab one off another car, that should be cheap as, as the guy at the wreckers will probably think it's a useless piece Try that first..... the others, well, exhaust is on the downpipe after the turn i think, sort of under the gearstick (but you have to get at it from below, i'd check that wiring too!) and the throttle sensor, well, i was pretty sure it was all built into the whole throttle unit?

    As above

    MAP in the intake tube to the TB - on the rear side approximately in the centre.
    The 2.2 has 2 lambdas - one before the cat and one afterwards.
    Throttle position sensor in-built onto the throttle body, and according to most accounts it isn't replaceable on it's own.
