The MAP sensor measures the pressure inside the intake manifold, giving the ECM the data it needs to calculate engine load and adjust fuel delivery and ignition timing accordingly. Signs of failure include: a check engine light with a MAP sensor code, rough idle, poor throttle response, reduced fuel economy, or black smoke from a rich running condition. Replace a faulty MAP sensor to restore accurate load-based fuel and timing control.
