Owners of 2005-06 4Runner, Land Cruiser, Sequoia and Tundra trucks with 4.7-liter 2UZ-FE engines may come into your store with an intermittent no-start complaint.
According to Toyota, the starting difficulties almost always occur after a hot soak, and may be accompanied by an illuminated Check Engine light with trouble codes P0335 and/or P01340 stored in PCM memory. An intermittent cam sensor signal is the most likely cause of the trouble. Installing an upgraded cam sensor, part #19300-50030, should put the starting issues to rest.
