What are symptoms of a failed MAP sensor?
Common symptoms include check engine light, rough idling, poor acceleration, increased fuel consumption, and difficulty starting.
Is the PS20092-12B1 an OEM part?
Yes, this is an original equipment manufacturer (OEM) Delphi sensor meeting factory specifications for the vehicles it's designed for.
What vehicles does this sensor fit?
This part is compatible with select General Motors vehicles including Chevrolet, GMC, Buick, and Cadillac platforms. Verify part compatibility with your vehicle before purchase.
Can I install this myself?
MAP sensors are typically mounted on or near the intake manifold and can often be replaced by experienced DIYers. Sensor location and difficulty varies by vehicle model.
