Description:
The Boost Pressure Sensor (BPS Sensor) is a critical component in turbocharged engines that measures the pressure of air being forced into the engine by the turbocharger. This real-time data is sent to the Engine Control Module (ECM) to optimize engine performance, fuel efficiency, and prevent engine damage by adjusting the air-fuel mixture, ignition timing, and boost levels.
Features
- High measurement accuracy, ECU can accurately measure the engine intake pressure;
- The product has good reliability and long service life, suitable for working in the harsh environment of the automotive system;
- Ceramic capacitor structure, good compatibility with the measurement medium.
Application
- Suitable for engine.

What happens when a boost sensor fails?
Boost sensor symptoms:
1. Check Engine Light – Often the first sign. You might see codes like P0236, which indicate pressure sensor issues.
2. Reduced Engine Power – The ECU may limit boost to protect the engine, resulting in sluggish acceleration or poor throttle response.
3. Erratic Boost Levels – You might notice boost spikes or drops, especially under load. This can feel like surging or hesitation.
4. Poor Fuel Economy – Incorrect boost readings can mess with the air-fuel ratio, leading to inefficient combustion.
5. Hard Starting or Rough Idling – The engine may struggle to start or idle smoothly due to inaccurate pressure data.
6. Failed Emissions Test – A faulty sensor can increase emissions or trigger a fault that causes automatic test failure.
What does a boost sensor do?
A boost sensor monitors the boost pressure within the intake manifold. The engine control module uses this data to gauge the proper amount of fuel, determine optimal ignition timing and operate the turbocharger wastegate.
Can I drive with a bad boost sensor?
Impact of a Bad Turbo Boost Pressure Sensor on Vehicle Performance A malfunctioning turbo boost pressure sensor can significantly affect your vehicle’s performance, engine efficiency, and even safety, making its proper functioning a priority.
