    Default 2000 Nissan Frontier Timing Adjustment (3.3L V6)

    I have a 2000 Nissan frontier that needs the timing checked/adjusted
    before I take to to be smogged. It's the 3.3L V6 engine.

    How do I stop the PCM from adjusting the timing automatically so that I
    can set it manually with a timing light?

    Cheers!

    I had a similar issue with my Sentra. I think around 1999, Nissan may
    have found a way to prevent the consumer from doing timing and other
    adjustments anymore. The CPUs in Nissan vehicles from 1999 onward seem
    to be a bit harder to diagnose unless you use the $1000 Nissan
    diagnosing computer, the CONSULT, only available and used by the
    dealer.

    In my car, I tried to adjust my timing to +10 degrees with a timing
    light. I dis-connected several sensors; the fans, tps, IACV etc. When
    adjusting the timing I would slowly move the distributor as the degrees
    went up: 3....5....5....5...5....5....5...7-then immediately BAM! 30
    degrees off the scale. Somehow the ECU picked up that I was adjusting
    timing and at seemed to just throw everything off. I tried several
    times. Same result.

    What I did instead was then to play by feel. I set the distributor to
    one point and drove for a while. I try to give it a week each time in
    case the ECU needs time to adjust to the new setting. While not
    perfect, that has worked out ok for me.
