    yellow or amber engine management light (EML)

    in Toyota Alphard Hybrid (2002 - 2008)

    Posted

    Hi guys, 

     

    I'm new to the world of the Alphard. My partner & I purchased ours back in June of this year - love it! 
    We too are having the exact issue described by Alphie though:

    The issue, i would say is clearly linked to ambient temperature because on a warm day, as soon as you put the engine under a bit more than normal load (maintaining speed going up an incline), the light is triggered. doesn't seem to happen on cooler days. Still doesn't seem to affect running/power & always resets on shutdown/start-up.

     

    I've had it diagnosed at two different garages, replaced the Bank 1 Lambda Sensor - EML still coming on. 
    I'm now going to try and clean the MAF sensor and see if I can get any joy from that. 

    Wondering if many other people have had this fault and what other possible fixes I can try? 
     

    Thanks so much in advance for any help!!!
