Which outcome results when an internal combustion engine's manifold absolute pressure (MAP) sensor fails high?

A)Air-fuel mixture becomes excessively lean
B)Engine enters limp mode immediately
C)Misfires during high acceleration events
D)Exhaust temperature decreases significantly

💡 Explanation

A lean air-fuel mixture occurs because the engine control unit interprets the high MAP signal as low engine load; therefore the ECU reduces fuel injection, causing a lean mixture rather than richer combustion associated with other sensor failures.
