Delphi PS20131 Manifold Absolute Pressure Sensor

Delphi PS20131 Manifold Absolute Pressure Sensor

The Delphi PS20131 manifold absolute pressure sensor delivers OE-calibrated voltage output for accurate engine load and air pressure readings. Built as a standard replacement MAP sensor, it supports precise engine management on select Cadillac, Buick, and Chevrolet applications.

• 5-volt MAP sensor with voltage-type output
• Black oval connector with 1 connector, 4 male terminals
• Bolt-on mount with 1 port and black plastic housing
• Standard replacement grade for direct service use
• Wiring harness not included

OE-Style Sensor Performance

Delphi PS20131 is engineered and validated to OE standards, with testing and calibration focused on accurate readings and consistent signal output. That helps the engine control module calculate manifold pressure correctly for fuel delivery, ignition timing, and drivability. This Delphi MAP sensor is a direct-fit service part for 2022 Cadillac CT4, 2016-2017 Buick Encore, 2016-2017 Chevrolet Cruze, and 2016-2017 Chevrolet Malibu.

This part cross-references Standard Ignition TX269 for the same application.

What This Sensor Helps Address

• Rough idle caused by incorrect manifold pressure input
• Hesitation or poor throttle response from inaccurate load data
• Check engine light related to MAP sensor signal faults
• Fuel trim issues tied to incorrect air pressure readings
• Driveability concerns on Buick Encore, Chevrolet Cruze, Chevrolet Malibu, and Cadillac CT4 applications

Installation Notes and Tips

Verify the connector shape, terminal count, and bolt-on mounting style before installation. The PS20131 uses a male oval connector with 4 male terminals and a single port, so matching the original sensor configuration is important for proper fitment. Confirm the vehicle application by year and model before replacing the sensor.

Quality Assurance

Delphi tests and calibrates its sensors to OE standards and uses stringent development and validation methods to support accurate readings and reduce repeat repairs. Part number PS20131 is built as a standard replacement manifold absolute pressure sensor for service work on confirmed applications.
