Delphi PS10121 manifold absolute pressure sensor for the 2005-2008 Buick LaCrosse V6 3.6L and other vehicles measures intake manifold pressure for the engine computer. The computer uses that signal to help set fuel delivery and timing.
- Silicone gel over the integrated circuit chip protects against shock and vibration
- Internal protection against moisture intrusion and vibration
- Tested and calibrated for accurate readings
Quick facts
- Part: Delphi PS10121 manifold absolute pressure sensor
- Fits: 2005-2008 Buick LaCrosse V6 3.6L and other vehicles
A failing manifold absolute pressure sensor can show up as a rough idle, weaker fuel economy or a check engine light. A vacuum leak, a restricted air filter or a faulty throttle position sensor can also be behind these signs, so track down the cause before you buy. This listing is a single sensor, which is the quantity per engine.
Fits
This manifold absolute pressure sensor also fits the 2004-2009 Cadillac CTS V6 3.6L, the 2005-2007 CTS V6 2.8L and the 2005-2009 Cadillac STS V6 3.6L. It fits more vehicles than these, so open the "Vehicles it fits" section and check your exact model and engine.

Frequently Asked Questions
Will the Delphi PS10121 fit the 2004-2009 Cadillac CTS V6 3.6L and the 2005-2007 CTS V6 2.8L?
Yes. Delphi PS10121 fits the 2004-2009 Cadillac CTS V6 3.6L and the 2005-2007 CTS V6 2.8L, with one sensor per engine.
Is the Delphi PS10121 right for a 2005-2009 Cadillac STS V6 3.6L?
Yes. Delphi PS10121 fits the 2005-2009 Cadillac STS V6 3.6L, with one sensor per engine. Use the "Vehicles it fits" section to check any other model and engine.
How is the circuit chip in this manifold absolute pressure sensor protected?
Silicone gel covers the integrated circuit chip to protect it against shock and vibration. The sensor is also protected internally against moisture intrusion and vibration.
What can a worn manifold absolute pressure sensor cause?
A worn sensor can bring on a rough idle, weaker fuel economy or a check engine light. A shop can read the sensor's signal with the right tools to confirm.
Does the Delphi PS10121 replace number 12575467?
Yes. 12575467 is one of the numbers Delphi PS10121 replaces, along with 225-1095, EC1785, 220315, AS305 and SU9489.
