    CEL code P3497, HELP

    Hey everyone,

    tried searching and couldn't get anything to come up.

    per autozone apparently this is a "lean condition on bank 2 while in the 4cyl mode"

    anyone else had this code? if so what fixed it?

    thanks

    Is that the only code thrown? How has the engine been running? Rough or normal?

    The things I would check then would be:

    1. An exhaust leak before the o2 sensor. Easiest to check when the engine is cold. Have someone start and hold the engine at 1500 rpm and look for a crack or signs of black soot.

    2. A vacuum leak or a leaking intake manifold gasket.

    3. The bank 1 o2 sensor. This can be bench tested with a digital VOM meter set to millivolts and a propane torch. Heat the tip of the sensor, holding the tip completely in the flame. Move the torch flame over the sensor tip. The tip should be hot enough to turn cherry red, and the flame must enter the
    opening into the sensor tip. Meanwhile, keep an eye on
    your meter. If you get a reading above 600 millivolts and the reading quickly changes with the movement
    of the flame over the tip, the sensor is good and can be reinstalled. When reinstalling it, check over all the o2 wiring and make sure you don't have a broken wire or bad connection.

    3. Weak fuel pump. Check fuel pressures.
