2024年11月15日 · The P0473 code is a diagnostic trouble code (DTC) that indicates an issue with the exhaust pressure sensor. Specifically, it signals that the readings from this sensor are higher than expected. This component plays a critical role in monitoring exhaust pressure levels within your vehicle’s emissions system.

2016年5月19日 · What Does Code P0473 Mean? Forced induction is used to improve power output and cruising fuel economy for a given engine displacement. Basically, exhaust gases rushing out the tailpipe are routed through a compressor, which …

Symptoms of a P0473 engine code may include: Unable to perform manual regeneration – burn off the soot out of the particulate filter. Looks like a catalytic converter but has temp sensors and pressure sensor probes inserted into it. If unable to perform regeneration, eventually may become a crank-no start.

The fault code P0473 in an automobile can be caused by a faulty Exhaust Back Pressure Sensor, an open or shorted harness for the sensor, or a poor electrical connection in the sensor circuit. To fix this issue, visually inspect the wiring harness and connectors, checking for any damage or broken, bent, pushed out, or corroded pins in the ...

The P0473 diagnostic trouble code (DTC) indicates a problem with the exhaust pressure sensor in the vehicle. The exhaust pressure sensor is a crucial component of the exhaust system that measures the pressure in the exhaust stream.

2024年11月1日 · p0473 表示“排气压力传感器‘a’电路高电压”状态，意味着发动机控制模块检测到排气压力传感器的电压高于预期值。 解决 P0473 代码的紧迫性如何？ 虽然不是立即紧急的，但建议尽早检查问题，以防止排气系统损坏或燃油效率下降。

1 天前 · What does the P0473 code mean? The P0473 code is a diagnostic trouble code (DTC) that indicates an issue with the exhaust pressure sensor A circuit. This sensor plays a crucial role in monitoring the exhaust system’s pressure to help optimize engine performance and emissions.

2019年4月19日 · Check for damaged components and look for broken, bent, pushed out, or corroded connector pins. An Exhaust Back Pressure (EBP) signal that is detected out of range (high or low) by the Engine Control Module (ECM) will cause the engine to ignore the EBP signal and disable exhaust back pressure operation.

排氣壓力感測器的作用是將排氣系統壓力以電信號的形式輸送給電子控制單元（ECU）。 如果ECU檢測到排氣壓力感測器A信號電路電壓在設定的時間段內（2.5秒）高於4.95伏，該故障碼會出現。 本站提供的信息僅供參考, 如果您需要更多的資訊, 請詢問您的工程師.

2019年4月19日 · Code P0473 Description. The Exhaust Back Pressure (EBP) sensor is a variable capacitance sensor that, when supplied with a 5-volt reference signal from the Engine Control Module (ECM), produces a linear analog voltage signal that indicates pressure.
