Detailed Description

Delphi builds this MAP sensor using OE development and validation methods, then tests and calibrates it to OE standards for accurate pressure signal output. The PS20112 is engineered to deliver consistent manifold pressure data to the engine control system, helping maintain proper fuel delivery, ignition timing, and drivability on vehicles such as Honda Civic, Honda CR-V, and Acura RDX applications. This part cross-references Standard Ignition AS636 for the same application.

What It Helps Solve

• Incorrect manifold pressure readings from a failing MAP sensor
• Rough idle caused by inaccurate engine load input
• Hesitation or poor throttle response during acceleration
• Fuel mixture and drivability issues tied to faulty sensor data
• Check engine light conditions related to MAP sensor performance

Installation Notes and Tips

Verify connector shape, terminal count, and mount style before installation. Confirm the vehicle uses a 5V MAP sensor with a 3-pin, bolt-on configuration, and inspect the intake manifold port area for contamination or damage before installing the new sensor. The Delphi PS20112 is listed for 2023 Acura Integra, 2022-2023 Acura MDX, 2019-2023 Acura RDX, 2021-2023 Acura TLX, 2016-2023 Honda Civic, 2017-2023 Honda CR-V, and 2018-2022 Honda Accord.

Quality Assurance

Delphi sensors are validated to OE standards and calibrated for accurate readings, supporting dependable service replacement performance. The PS20112 reflects Delphi’s OE-focused sensor development process for emission control and engine management applications.
