Keep the engine control module reading intake manifold pressure accurately with the Delphi Manifold Absolute Pressure Sensor PS10000. It installs as a direct-fit replacement across a long list of GM cars, trucks, and vans — including the 2005-2006 Buick LaCrosse, 1996-2005 Buick LeSabre, 1995-2005 Cadillac DeVille, 2000-2005 Chevrolet Impala, 1999-2008 Chevrolet Silverado 1500, and 1996-2008 Chevrolet Tahoe — with many more applications listed on the Buyer's Guide tab.
- Measures manifold absolute pressure: monitors pressure in the intake manifold and reports it to the engine control module so it can gauge engine load and air density.
- Feeds fuel and spark control: the ECM uses the MAP signal to help set fuel delivery and ignition timing.
- Direct-fit replacement: designed to install in place of the original sensor on the listed applications.
A rough idle, hesitation under load, poor fuel economy, or a check-engine light with MAP-related trouble codes can be signs this sensor may need replacing. Diagnose the cause first; if a faulty manifold absolute pressure sensor is the problem, PS10000 replaces it.
Manufacturer part number PS10000.
Frequently Asked Questions
What does this MAP sensor do?
It measures the absolute pressure inside the intake manifold and sends that reading to the engine control module, which uses it to help calculate engine load and air density for fuel delivery and ignition timing.
Will the PS10000 fit my vehicle?
It is a direct-fit replacement for a large list of GM applications, including many Buick, Cadillac, Chevrolet, and GMC models. Check the Buyer's Guide tab to confirm your exact year, make, and model.
What are signs a MAP sensor may need replacing?
Common signs include a rough idle, hesitation under load, poor fuel economy, or a check-engine light with MAP-related codes. These can have other causes, so diagnose before replacing.
Is this a new sensor or a rebuilt unit?
This listing is for the Delphi Manifold Absolute Pressure Sensor, part number PS10000. Refer to the product details and images for the exact item shipped.
Should I clear codes or recalibrate after installing it?
