Standard Motor Products MAP sensors are direct, high-quality replacements for your vehicle's worn, damaged, or malfunctioning manifold absolute pressure sensor. These sensors accurately produce voltage or frequency as manifold pressure changes, and the computer uses this information to measure engine load so that the ignition timing can be advanced and retarded as needed. On engines with a speed density type of fuel injection, the MAP sensors also help the PCM estimate airflow. Malfunctioning MAP sensors can often cause problems such as an intermittent check engine light, hesitation when accelerating, elevated emissions, and poor engine performance.
