What does a turbo boost pressure sensor do?
The Turbo Boost Sensor measures turbo manifold pressure to the ECM, and is used to calculate air density and the required fuel delivery for optimum combustion. If it fails, the system may not add fuel under boost and can result in loss of power and possible engine damage.
Where is the turbo boost pressure sensor located?
intake pipe
The boost pressure sensor is located inside the intake pipe in front of the throttle valve. The Sensor measures the pressure and sends the data to the engine management system.
What happens when the turbo boost sensor is damaged?
The turbo boost pressure sensor is damaged and responding relatively slower to changing pressure. When the P0236 code is triggered, the PCM reacts by entering into an engine management failure mode, as it ignores the real manifold pressure reading and assumes another reading, limiting the engine capability.
What do you need to know about boost sensor?
A boost pressure sensor is a part of a turbocharged engine that measures and regulates the air pressure and controls the boost. Here are the most common symptoms. Ask a mechanic
How does a boost pressure sensor work on a supercharged engine?
Boost pressure sensors control the boost level produced in the intake manifold of a turbocharged or supercharged engine. They affect the air pressure delivered to the pneumatic and mechanical wastegate actuator. Fig. 1 shows a typical boost pressure sensor. Fig. 1 The boost pressure sensor measures the absolute pressure before the throttle valve.
What’s the voltage of the boost manifold sensor?
When the manifold pressure is low (high vacuum) sensor voltage output is 0.25-1.8V at the ECM. When the intake manifold pressure is high due to turbo boost, sensor voltage output is 2.0-4.7V. Pressure range is between 10kPa and 350kPa. The sensor receives a 5V reference from the ECM.
