    Default Toyota 1az-fse dtc p1633

    Happy New year everyone.
    I got a problem working on a toyota noah 2001.engine check light comes on whenever start the engine.The only dtc is p1633 and the engine won't revv up whenever the dtc is detected.Couldn't find any specific repair info for this Dtc, so I've already replaced the Ecu and Throttle body with known good one(for test).
    Still the same ...no improvement.

    Im wondering if somebody help me some advice.
    THANKS

    The error code P1633 also refer to the KAM (Keep Alive Memory) voltage too low. It may be due to the weak battery or defective alternator. Recharge the battery, remove the negative battery terminal for 20 sec or more and relearn the idle speed. Good Luck.

    Thanks mate
    I've managed to fix it.
    It was nothing but wiring problem.Disconnected all the connectors from fuse boxes spray electronics contact cleaner and put them back.That's it and it's done.
