Turbo Boost Sensor: Description and Operation
Operation
OPERATION
When the intake manifold pressure is low (high vacuum) sensor voltage output is 0.25-1.8 volts at the ECM. When the intake manifold pressure is high
due to turbo boost, sensor voltage output is 2.0-4.7 volts. The sensor receives a 5-volts reference from the ECM. Sensor ground is also provides by the
ECM. The ECM uses boost pressure combined with intake air temperature to determine the volume of air entering the engine.
