MAP Sensor - 3-Bar LSA/LS9 6.2L

The MAP Sensor - 3-Bar LSA/LS9 6.2L is an original equipment style manifold absolute pressure sensor engineered for high-performance Chevrolet LS-based engines. This OE-specification component monitors intake manifold pressure in real time, allowing your engine control module to calculate precise fuel delivery and ignition timing across all operating conditions. Whether you're maintaining a stock LSA or LS9 supercharged platform or tuning a custom LS build, this 3-bar MAP sensor delivers the pressure feedback accuracy that modern fuel injection systems demand.

The 3-bar pressure range is specifically calibrated for naturally aspirated and moderately boosted LS engines, measuring from 0 to 3 bar absolute pressure with factory-grade linearity and response speed. The sensor housing is compact—measuring 3.05 x 1.3 x 3.45 inches—and integrates seamlessly into OEM intake manifold ports without modification. Its lightweight construction at 0.04 lbs minimizes parasitic engine load while maintaining robust electrical connectivity and sensor durability under sustained high-RPM operation, making it an ideal choice for both street and track applications requiring reliable air-charge calculation.

This component is essential for any LS9 or LSA powered vehicle—factory-backed Corvettes, Cadillacs, and Camaros—as well as custom LS swaps where OEM sensor compatibility is mandatory for CEL-free operation. Technicians and tuners rely on Chevrolet Performance sensors to maintain signal integrity and prevent lean-condition faults that can damage cylinders under boost. Direct plug-and-play installation via the factory sensor port ensures no wiring modifications are required, and the original equipment design guarantees compatibility with all GM LS9 and LSA factory ECU calibrations.
