The Manifold Absolute Pressure sensor provides boost pressure information to the engine control unit to calculate air density for determining the engine’s air mass flow rate. A faulty MAP sensor can upset the fuel mixture and ignition timing, causing a surge, rough idle, and a rich fuel condition which can lead to spark plug fouling and a loss of power and fuel economy.
Replace your faulty sensor to restore engine performance and fuel economy.
*This is the large design MAP sensor. For the small design, please see OEM PN 03890651B, 03890651C or 03890651D. Please check existing part prior to ordering.
