    Hey guys,

    My Check engine light has been coming on and off for the past 3-4? months. It doesn't run any different whatsoever, only comes on when it's under light load, then goes off when it's under full load.

    Asked my mate (mechanic) to check it out with his snap-on scanner but couldn't get it to work.

    Wanting to know if anyone has a list of codes, pins to bridge to attain said code etc..

    Or if anyone knows wtf to do.

    Cheers,
    -Roy

    Bridge the Te1 & E1 terminals for fault codes.

    <div class='quotetop'>QUOTE (w84me @ Aug 26 2008, 05:58 PM) </div>Its meant to stay on until the engine is started, so that isn't any problem.

    Wouldn't suprise me actually. I got mine put back in and they joined the cable in about 4 places, because they had to extend it. Nothing but problems since. Question. Is there any correct way to lengthen an O2 sensor, using heatshrinkable inline joiners, or just don't do it? Cause where they welded it back in is like under the passenger floor/seat. So it's a fair whack longer.

    perhaps use one long piece to eliminate a few joins?

    alwasy bind the joins fist then solder as the solder doesn't conduct as well as the copper of the wire. heatshrink will make the neatest job but quality electrical tape should also be fine.

    I have inline heatshrinkable joiners that I used to use at work. So I'm gonna re-do it today, see if it changes anything.

    Went down to my local parts store and ordered a new bosch O2 sensor. Can't remember the exact part number. Will post it up when I pick it up. Cost me $105 due to it having to be posted from melbourne. $85 retail.

    Talked to the guy he actually used to work for bosch and said under no circumstances should the cable from the sensor to the plug ever be cut as it fucks it out. I'm going to have to extend the loom part as my local exhaust shop welded the O2 in way too far down the exhaust and joined the cable. So now I'm up for more cash to get it working properly when I originally went to the exhaust joint to get it put in and work.

    And the car fucks itself again thanks to the dizzy.

    /end anger.
