Detailed Description

Global Parts 1815121 is built for vehicles that rely on accurate manifold pressure input to manage fuel delivery and engine operation. By reading pressure inside the intake manifold and relaying that signal to the ECU, this MAP sensor supports proper air/fuel mixture calculation in everyday driving conditions. It is a fitment-based replacement for 2016-2021 Honda Civic and 2019-2021 Acura RDX models, making it a practical choice when servicing drivability or sensor-related faults on those platforms.

The sensor uses a single oval female connector, blade-style male terminals, and a bolt-on mounting design. Those details matter when matching the original part configuration during replacement, especially on Honda Civic and Acura RDX applications where connector shape and terminal layout must align with the vehicle harness.

What This Part Helps Address

• Check engine light related to MAP sensor performance
• Rough idle caused by incorrect manifold pressure readings
• Hard starting or hesitation tied to air/fuel calculation errors
• Poor throttle response from inaccurate ECU input
• Fuel mixture concerns on 2016-2021 Honda Civic and 2019-2021 Acura RDX

Installation Notes and Tips

Confirm the connector shape, terminal count, and mount style against the original sensor before installation. Inspect the intake manifold port and electrical connector for damage, corrosion, or debris before fitting the replacement. After installation, clear diagnostic trouble codes and verify sensor readings with a scan tool if the vehicle previously stored MAP-related faults.

Quality Assurance

Global Parts supplies replacement emission control sensors for service applications that require accurate signal input and OE-style fitment details. Part number 1815121 is specified for select Honda Civic and Acura RDX vehicles based on the listed application data.
