The ZTech Mack Boost Pressure Sensor (20706228 / 577.62533OE) monitors turbocharger boost pressure in Mack diesel engines, providing the ECM with data needed to optimize fuel delivery for maximum power and efficiency. Accurate boost pressure measurement prevents over-boosting that damages engine components and under-boosting that reduces power and efficiency. A faulty boost sensor causes power loss, excessive black smoke, turbo-related fault codes, and poor fuel economy in Mack trucks.
