    Bro E-Tech, on PT2 Accord ECU, where is the IC17 located? because in this ECU, layout totally different, so I can't find it. But tracing from A7, followed it to ZQ17.

    Just want to confirm before I solder in a replacement.

    No, this board doesn't use the TA8903SN power supervisor ic.
    In fact that was the component i looked for first before tracing the A7 back to ZQ17.
    The board has nothing in common with the normal P08 b/d series ecu.

    Just though i'd try fixing it since encountered the same problem before in B/D series ecu.
    Its late, so i guess i'll try checking the part to see what it actually does tommorow. Thanks for the reply.

    Not solved yet, still got solid cell. :bawling:
    double checked all trace again, not see any abnormal.
    can you specific the area that i have to inspect?

    note that the P27 ecu is quite same as P28 but it is no VTEC.

    Big thank.. e-tech

    Actual worst case senario... big cap leak and short or circuit broken.... becomes hot and burnt a hole
    on the ecu pcb. Car stink from the smell of burnt pcb. Car cannot start.

    Others will be like poor idling or engine check light comes on....

    I have experience quite same case for my P30 | ECU. The capacitor leaked and the trace is burn. This cause vtec sometimes on and off. My friend help me replace the cap and luckily it still works.
