Scanner read out - 1994 Olds Cutlass Ciera 3.1 - "manifold pressure switch" GM parts department shows no MAP pressure sensor - mechanic stated model with VIN# M - may not have MAP pressure sensor - Is it possible this model the pressure sensor and MAP air-flow sensor are integrated into one - no visible sign of a manifold pressure sensor in the engine bay -
