What the MAP Sensor Does

The MAP sensor measures the air pressure inside the intake manifold and sends that data to the engine control unit. The ECU uses this information to adjust fuel delivery, ignition timing, and boost control (if equipped). A properly functioning MAP sensor helps maintain:

• Consistent fuel economy
• Smooth throttle response
• Stable idle and drivability
• Correct air–fuel ratios under all driving conditions

Common Signs of a Failing MAP Sensor

• Rough idle or stalling
• Poor fuel economy
• Hesitation or sluggish acceleration
• Check Engine Light (CEL) illumination
• Black exhaust smoke from running rich
• Hard starting or inconsistent throttle
