The SPOOLOGIC Manifold Absolute Pressure (MAP) Sensor SL-600-064 is a direct-replacement boost-pressure sensor for the factory Holset HE351CW turbocharger application on 2003-2007 Dodge Ram 2500 3500 5.9L Cummins. It reports intake manifold pressure to the ECM in real time for closed-loop boost control, fueling, timing, and overboost protection.

This manifold absolute pressure (map) sensor is a brand new direct-replacement unit built to OEM specifications and pre-tested to match the original factory part. It plugs into the factory engine harness and ECM without re-programming or modification — fits the original factory part out of the box, no tuning or piggyback module needed.

Common HE351CW Manifold Absolute Pressure (MAP) Sensor Failure Symptoms

If your 5.9L 24v Cummins truck is showing any of these symptoms, the manifold absolute pressure (map) sensor is most likely the cause:

• Check engine light with P0237, P0238, or P0107/P0108 codes — MAP circuit low/high input or boost pressure sensor fault
• Loss of boost or low boost under load — ECM not seeing accurate manifold pressure to command full turbo output
• Black smoke under acceleration — incorrect manifold pressure data causing fueling errors
• Hard starting, rough idle, or hesitation — MAP reference drifting at idle and part throttle
• Reduced power and fuel economy — boost control and fueling tables operating off a bad pressure signal

Premium Replacement — Same Quality as Factory OEM

Every SPOOLOGIC manifold absolute pressure (map) sensor is built to OEM electrical and mechanical specifications, pre-tested before shipment, and packaged with a 1-year limited warranty. You get factory-grade fitment and signal accuracy without paying dealer pricing.
