HHCSOP MAP Sensor for Jeep & Dodge 1997–2003 – Direct-Fit Replacement, Fast Response

HHCSOP Manifold Absolute Pressure (MAP) sensor is a direct-fit replacement for multiple 1997–2003 Jeep and Dodge engines, providing fast pressure readings and stable operation across wide temperatures.

This MAP sensor is engineered as a plug-and-play substitute for a long list of OE and aftermarket part numbers (including 5S2434, 56029405, AS88 and others). It reads intake manifold pressure and sends that signal to the engine control unit so the ECU can manage fuel and ignition timing. The unit offers sub-3% accuracy over normal operating temperatures and a response time under 2 milliseconds, plus a protective coating to help resist corrosive agents in the intake tract.

How will this MAP sensor fit my vehicle?

The HHCSOP sensor is designed to replace specific MAP part numbers and fit a wide range of late-1990s and early-2000s Jeep and Dodge models. Before installing, verify the part number and connector shape against your original sensor and the included compatibility list.

• Compatible models include Jeep Cherokee XJ (1997–2001), Grand Cherokee ZJ (1997–2003), Wrangler TJ (1997–2002)
• Dodge compatibility: Ram 1500/2500/3500 (various years), Dakota, Durango, Ram Van, B-series trucks, and Viper (see full list)
• Replaces OE numbers such as 5S2434, 56029405, AS88 plus many aftermarket equivalents

What performance and durability features does it offer?

This sensor emphasizes fast response and consistent readings in different thermal conditions. A chem-resistant coating and a design rated for extreme temperatures help maintain function in the intake environment.

• Response time: under 2 milliseconds for quick signal delivery to the ECU
• Operating range: -40°C to 125°C with a maximum error of about 3% between 0°C and 85°C
• Protective coating reduces risk from fuel vapors and intake contaminants

How simple is installation and what should I check?

Installation is straightforward for most mechanically capable owners; the unit is designed as a direct replacement and uses the factory mounting and electrical connector. Still, double-check fit and inspect wiring and vacuum lines for wear before installation.

• Confirm electrical connector pins match your vehicle harness before fitting
• Compare the sensor body and mounting tabs to the original part for secure attachment
• Clear intake leaks and ensure vacuum line routing is correct after installation

How will using this MAP sensor affect engine management?

By providing accurate manifold pressure readings, the sensor enables the ECU to adjust fueling and timing more precisely than if the sensor were failing or out of spec. Proper sensor function supports smoother idle, steadier throttle response, and consistent drivability when combined with a healthy engine and fuel system.

• Supports ECU calculations for air mass and ignition timing adjustments
• Helps maintain stable idle and consistent performance across loads
• Quick response minimizes lag when throttle inputs change rapidly

Who is this for: Technicians, DIY mechanics, and vehicle owners who need a reliable, quick-response MAP sensor for older Jeep and Dodge models. It suits anyone replacing a failing or suspect MAP unit who requires compatibility with listed OE numbers and expects durable, temperature-resistant performance in everyday driving and light-duty work conditions.
