Question

map sensors are being discussed. autozoner a says: \a map sensor trouble code could be caused by a disconnected or ruptured vacuum line.\ autozoner b says: \a map sensor with a ruptured vacuum line will cause the fuel delivery system to run rich.\ who is correct? autozoner a autozoner b both autozoners neither autozoner

Explanation:

A disconnected or ruptured vacuum line can cause a MAP (Manifold Absolute Pressure) sensor trouble - code. Also, a ruptured vacuum line can lead to the fuel delivery system running rich as the MAP sensor provides incorrect pressure data to the engine control unit, which then adjusts the fuel - air ratio.

Answer:

C. Both AutoZoners
