Walker 225-1319 Manifold Absolute Pressure Sensor

Walker MAP Sensor for OE Replacement

Walker Products Part Number 225-1319 is a manifold absolute pressure sensor built for direct OE-style replacement. It measures intake manifold pressure and sends that signal to the ECM so the engine can calculate load and adjust fuel delivery and ignition timing.

This Walker Sensor Only line focuses on the sensor component itself for service work where the existing connector and mounting setup are being retained. It is a practical choice for Fiat 500, Fiat 500L, and Dodge Dart applications that need accurate MAP sensor input for drivability and emissions control.

Key Features

• Manifold Absolute Pressure sensor for engine load calculation
• OE replacement electrical output, pressure range, and connector fit
• Black plastic body with oblong female connector
• Blade terminals, 4 terminal count, plug-in fitting
• Built for high engine bay temperatures, vibration, and intake air contaminants
• Walker Part Number 225-1319

Detailed Description

Walker Products 225-1319 is engineered to measure pressure inside the intake manifold and communicate that data to the ECM for precise fuel and ignition control. The sensor is designed to match OE specifications for signal output and connector fit, helping restore proper engine management on vehicles that rely on accurate manifold pressure data. This part cross-references 4627187AA and 68093409AA for the same application.

Compatible With 2012-2016 Fiat 500, 2013-2016 Dodge Dart, and 2014, 2020 Fiat 500L, this MAP sensor supports service repairs where the original sensor has failed or is sending inaccurate readings. Walker 225-1319 is also listed under interchange AS620.

What It Is Used For

• Check engine light related to MAP sensor performance
• Rough idle or unstable engine speed
• Hesitation, poor throttle response, or reduced power
• Incorrect fuel mixture caused by faulty manifold pressure data
• Emissions and drivability issues tied to engine load calculation

Installation Notes and Tips

Verify connector shape, terminal count, and port layout before installation. This sensor uses a female oblong connector with blade terminals and a plug-in fitment, so the vehicle harness and mounting point must match the original configuration. Confirm the application by year, make, and model before service.

Quality Assurance

Walker MAP sensors are built to OE replacement standards and tested for accuracy, responsiveness, and long-term reliability. The design is intended to withstand heat, vibration, and intake contamination common in the engine bay while maintaining consistent ECM signal output.
