HHCSOP MAP Sensor for Dodge Ram 1500/2500/3500 — Fit 2003–2020, 2 ms Response, Durable

HHCSOP Manifold Absolute Pressure (MAP) Sensor is a direct-fit replacement sensor that measures intake manifold pressure for compatible Dodge, Jeep, Chrysler and Volkswagen models, restoring accurate engine load data.

If your vehicle’s engine control unit needs reliable intake pressure readings, a new MAP sensor like this HHCSOP unit supplies stable, fast measurements and resists harsh under-hood conditions. This SKU replaces OE numbers including AS321, 56028562AA/AB and several others, and fits many model years across Dodge Ram, Charger, Challenger, Jeep, Chrysler and related platforms. The sensor is built to work across a wide temperature range and responds in under 2 milliseconds to changing manifold conditions.

How does this MAP sensor affect engine performance?

The MAP sensor provides the ECU with instant pressure data so fuel delivery and ignition timing are calculated accurately. A functioning sensor helps the engine run smoothly by reducing guesswork in air/fuel estimation, especially under varying loads and altitudes.

• Restores correct manifold pressure input to ECU for proper fueling
• Response time under 2 ms for near-instant adjustments
• Precision maintained within 3% error from 0℃ to 85℃

Which vehicles and part numbers is this compatible with?

This HHCSOP MAP sensor is intended as a fitment replacement for many Dodge, Jeep, Chrysler and related models from the early 2000s through recent years. Confirm compatibility with your vehicle by checking OEM numbers and the part photo before ordering.
