Description:
The Exhaust Back Pressure Sensor (EBP Sensor) is a critical component that monitors the pressure of exhaust gases in the exhaust system. This sensor measure the engine exhaust back pressure and output it to the ECU to calculate the engine load and adjust the EGR rate.
Features
- High measurement accuracy, ECU can accurately measure the engine exhaust 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 measuring medium, insensitive to sulfur in the exhaust gas.
Application
- Suitable for engine.

What are the symptoms of a bad exhaust back pressure sensor?
What happens when an exhaust pressure sensor fails?
A faulty exhaust back pressure (EBP) sensor can cause a variety of performance and efficiency issues in your vehicle. Here are the common symptoms to look out for:
1. Reduced Engine Power: The engine may feel underpowered or sluggish, especially under load or during acceleration.
2. Poor Fuel Efficiency: Incorrect exhaust pressure readings can lead to inefficient fuel usage.
3. Excessive Exhaust Smoke: You might notice increased smoke from the exhaust, which can indicate improper air-fuel mixture.
4. Rough Idling: The engine may idle unevenly or vibrate more than usual.
5. Engine Hesitation or Stalling: Hesitation while accelerating or stalling at low speeds can occur.
6. Check Engine Light: Fault codes related to the EBP sensor, such as P0470 or P0471, may appear.
7. Turbocharger Issues: The turbo may not function correctly, as it relies on accurate exhaust back pressure readings to operate efficiently.
What does an exhaust back pressure sensor do?
An exhaust back pressure (EBP) sensor monitors the pressure of exhaust gases in the exhaust system. This information is crucial for modern diesel engines, as it helps the engine control module (ECM) make adjustments to ensure optimal performance and reduce emissions
What is a normal exhaust back pressure reading?
A normal exhaust back pressure (EBP) reading depends on the engine type and operating conditions, but here are some general guidelines:
1. At Idle: Typically less than 1.5 psi (10 kPa) for most engines.
2. Under Load or Higher RPMs: Can range between 3 to 5 psi, but anything significantly higher may indicate a restriction in the exhaust system.
