SPOOLOGIC Manifold Absolute Pressure (MAP) Sensor

The SPOOLOGIC SL-600-064 Manifold Absolute Pressure Sensor is designed for 2003–2007 Dodge Ram 2500 3500 trucks equipped with the 5.9L Cummins. It supplies manifold-pressure feedback for the engine’s load calculations and boost-monitoring strategy.

Features

• Brand-new manifold absolute pressure sensor
• Measures absolute intake manifold pressure
• Factory-style electrical connection and mounting
• Provides pressure feedback for engine-load and boost monitoring

What's Included

• 1 SPOOLOGIC Manifold Absolute Pressure Sensor — SL-600-064

Fitment

• 2003-2007 Dodge Ram 2500 3500 5.9L Cummins

MAP Sensor Operation

The pressure signal helps the ECM evaluate cylinder air supply as engine load changes. The 5.9L common-rail engine’s air system differs from the later 6.7L VGT/EGR system; a MAP sensor on this application does not directly position turbocharger vanes.

Common MAP Sensor Fault Codes

• P0237 / P0238: MAP/boost-pressure sensor voltage low/high on applicable 5.9L calibrations.
• P0069: MAP/barometric pressure correlation, where supported. Confirm the exact code description for the vehicle.

Code availability varies by model year and calibration. A stored code identifies a condition to diagnose; it does not prove the component has failed.

Diagnose Before Replacing

With the key on and engine off, compare absolute manifold pressure with local barometric pressure using the factory tolerance. Inspect the pressure passage, connector, reference supply, signal return, and signal circuit. If pressure data is believable but boost is low under load, check the charge-air system and turbocharger rather than assuming the sensor is defective. Check the installed turbo and pressure plumbing if the truck has been modified; do not assume that a performance complaint originates in the MAP sensor.

Installation Notes

Keep debris out of the pressure port and intake opening. Inspect the seal or hose connection, use the application-specific tightening procedure, and verify live pressure after installation. Do not apply compressed shop air to the sensing element.
