Some customers may comment on a check engine light illuminated with a message that displays Engine Power is Reduced on the DIC.
Upon further investigation, a scan tool may reveal DTC P0101 set in history or as current.

This condition may be caused by snow getting ingested into the air cleaner box and restricting the air intake to the engine.

2. Verify the condition by questioning the customer as to when the condition occurs (during or right after a snow storm).

1. 
   
   
   
   ​
   
   <LI type=1>Using the new air cleaner cover, GM P/N 20821430, drill five 25 mm (1 in) holes in the cover as shown. <LI type=1>Install the emission label, GM P/N 19180225, to the new cover. <LI type=1>Remove the existing air cleaner cover and install the new cover with holes. Provide the customer with the original cover and instruct them to reuse for summer.
   [*]Instruct the customer to install the grille opening section only (1st design, 2 piece cover) of the winter front. If the customer has a one piece cover (2nd design) or no cover at all, obtain the grille opening section only, GM P/N 25822811 (GMC) or 25822812 (Chevy). The air cleaner cover with holes and the grille opening cover must be installed to ensure a complete repair. This repair allows warm air to be circulated into the air cleaner, which melts the snow.
