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 MAP (Manifold Absolute Pressure) sensor measures intake manifold pressure to adjust fuel delivery. A disconnected/ruptured vacuum line disrupts pressure readings, triggering a trouble code (AutoZoner A is correct). A ruptured line lets extra air into the manifold; the sensor interprets this as lower pressure (high engine load), so the ECU adds more fuel, making the system run rich (AutoZoner B is correct).

Answer:

Both AutoZoners
