Condition
Some customers may comment that the check engine light is on.
A scan tool may reveal DTCs P0171 and/or P0174 set in history or current. If the air flow to the air intake/air cleaner assembly is disturbed, the DTCs may be induced.
Cause
This condition may be caused by a gap between the upper radiator air baffle and the bumper beam combined with some beam holes. The gap and holes may cause an air flow disturbance to the air intake/air cleaner assembly. Refer to the pictures below for further clarification.
