Need to fix poor throttle response, low boost performance, or a check engine light on your Cummins? The Walker Manifold Absolute Pressure (MAP) Sensor is a direct-fit replacement designed to restore accurate intake manifold pressure readings on 6.7L Cummins applications. The MAP sensor plays a critical role in engine management by measuring boost and intake pressure, enabling the ECU to calculate airflow, fuel delivery, and overall engine load. When it fails, you may notice sluggish acceleration, poor fuel economy, excessive smoke, and inconsistent turbo response. This sensor restores that signal to factory accuracy, so your engine runs clean, strong, and properly fueled again.

Built to OE fit, form, and function standards, the Walker MAP sensor uses durable internal components engineered to withstand extreme heat, vibration, and continuous underhood pressure cycling. The housing is designed to resist oil vapor contamination and moisture intrusion, both of which commonly degrade sensor accuracy over time. Each unit is fully tested to OE specifications to ensure precise pressure signal output and stable communication with the ECU, delivering consistent boost readings, improved drivability, and long-term reliability in demanding diesel applications.
