    Anyone know the resistance of the 2007 O2 sensors? My maint manual only tells you how to remove and replace.

    Trying to trouble shoot a rough idle would like to check the resistance of the O2 sensors.

    Thanks !!

    Is it throwing a code?

    P0131 Front O2 sensor low (lean)
    P0151 Rear O2 sensor low (lean)
    P0132 Front O2 sensor high (rich)
    P0152 Rear O2 sensor high (rich)
    P0134 Front O2 sensor open/not responding
    P0154 Rear O2 sensor open/not responding

    No codes , just running rough in traffic and idle when warm. Cold Idle seems to be ok

    KN airfiler ? Could the high flow airfilter be an issue? No other upgrades. Only other non stock item is wrapped exhaust pipes.

    Wrapped exhaust pipes not a good idea, the metal gets very brittle.

    The K&N shouldn't be a problem but it will cause a lean condition that may be the issue, more like manifold to head leakage.

    Will check for leaks. Maybe throw the stock air filter on and see if it make a differance. Thanks for the heads up. Will let you know what I find.

    This is what you need, it's in the Electrical Diagnostic Manual
