Diagnostic Aids

Fuel contamination, such as water and alcohol will effect fuel trim. A malfunctioning MAF sensor can cause a rich condition and set this DTC. See DTC P0101: MAF SYSTEM PERFORMANCE (CENTURY, GRAND PRIX & MALIBU) . If an intermittent condition is suspected, see INTERMITTENT TROUBLE CODE DETERMINATION  under SELF-DIAGNOSTIC SYSTEM.
