Oil Cap Throws Code

This bulletin applies to 2010 Chevy Aveo vehicles. The customer may comment on a service engine soon light on.

The technician may find a DTC P0171 for lean fuel trims.

If published diagnostics have been performed with no trouble found, one area of concern that has been noted is the engine oil fill cap. The cap may not be properly seated in the camshaft cover.

The cap O-ring seal may be cut or damaged. It is further possible that the engine oil dipstick may not be seated in its tube.

Repair as needed.
