    Default BX 16 Valve - done something stupid...

    Hi all,

    I spent the weekend doing routine maintenance stuff - changed the engine oil and filter and replaced the LHM. I pulled off the big rubber hose that runs from the air cleaner to throttle body so that I could remove the cold air intake hose so that I could get to the bleed screw on the accumulator. I got the LHM changed, put it all back together and I now have the engine check light on constantly.

    I guess I've managed to unplug some engine sensor somewhere, but despite staring at the engine for hours and swearing at it in any number of languages, I can't see what I've done.

    So, my questions are:
    - Anyone done this before and has a pointer to share?
    - And can anyone point me to somewhere on the web with the engine check codes and how to retrieve them? I remember seeing an article somewhere that described fault codes displayed by flashing the engine check light. I *think* you had to jumper a connector in the engine bay.

    Thanks!
    Duncan

    Did you disconnect the battery ?? If so, try the alarm remote. the car maybe imobilised.

    If it's an aussie delivered car it'll likely have a mongoose alarm fitted.

    Peugeotlogic has a blurb on the procedure - but no pictures.

    How to extract fault codes

    If you really can't find any plugs missing, I guess the first step is to make sure the hose is on properly and clamped (and that there are no splits in the hose) and take it for a drive. It could just be a massive air leak that it's complaining about.
    Regards,

    Thanks gents,

    The engine check light doesn't extinguish before the engine starts which is why I'm pretty sure it's a sensor issue.

    The alarm is long gone, so definitely not that... :-)

    Thanks for the link - that's exactly what I was looking for.

    Thanks,
    Duncan

    Here is the factory manual on how to extract the codes.

    ECU Fault Codes

    It's reasonably easy if you rig up some twisted pair wire back to the drivers position. I don't even worry about a push button switch. Just hold the wires together for 3-4 secs. Once you have the code, it's easy to identify which sensor is faulty. I'm going to take a punt on the canister purge valve.

    If you started the engine before putting the big rubber hose back on, or before tightening the clamps on it, or before plugging the sensor back in on the side of the air filter, then the MAF would register a fault (too much air) and will keep it until you retrieve and clear it.

    Cheers, Erik

    No, it doesn't work like that. If there is a fault, it will be recorded until cleared. If you fix the fault, it will still be stored until cleared, but the light will go out. So it's possible to have multiple faults stored, showing the history of faults. If the fault remains, such as the knock sensor being disconnected, the light will remain on until the fault is corrected. Under this condition for example, the ECU drops into limp home mode, severely retarding the ignition advance.

    Thanks everyone,

    I put the regassed spheres back on last night and the engine started and ran faultlessly - the error cleared itself.

    No doubt it'll be back... :-)

    Cheers,
