Problem overview

A defect in manufacturing may cause camshaft failure in the 2007 Toyota Tundra. The camshaft is too soft from the factory, and cam lobe wear is inevitable. This may cause:

  • Check engine light illumination
  • OBD trouble code p0300
  • Rough idle
  • Loss of power
  • Poor fuel economy

To correct the issue, the camshaft must be replaced using the revised part number.

Maintaining the engine properly with the correct engine oil and oil change intervals can reduce the risk of camshaft failure. Also, letting the engine warm completely before any spirited driving or towing will help.
