    Default Can you guess the fault?

    Ok so I thought I'd share the info and have some fun alone the way

    A pat on the back if you guess what's the fault

    It's a 1.8 petrol z18xe engine
    The symptoms are rough idling and hesitation while cruising at motorway speeds
    The fault codes are
    P0110 - intake air temp sensor 1 circuit

    P0130 - O2 sensor circuit (bank 1 sensor 1)

    P0220 - throttle position sensor/switch b circuit

    P0340 - camshaft position sensor a circuit*

    P1550 - Electronic throttle system (ETS) - in emergency mode

    Enjoy

    Similar symptoms to you except not on motorways. I have the P0340 - camshaft position sensor a circuit error.
    I have a new Camshaft sensor but you need to remove the timing belt and vernier wheel to get to the sensor (Nice design Vx!)

    Not maf sensor nor a blown fuse but keep the guesses coming in

    Very close but good enough, it's actually the multiplug which goes onto the ecu has a poor connection where the terminals have opened up inside the plug this loom runs from the ecu over the top of the engine connecting all the sensors and the injectors.

    Just goes to show it's not always a good idea to throw money at your car replacing everything that shows up when code reading (like the previous owner, HA!) hence the back to basics advise and a good old wiggle test while watching live readings, I hope this helps and most of all saves everyone some money
