2023年9月2日 · Need More Help with a P0087 Code? The main problem that can cause the P0087 code is low fuel pressure. This error code is similar to the P0088 when the problem is in a raised fuel pressure. The sensor on the fuel rail measures fuel pressure and how much fuel the pump needs to deliver.

2025年2月15日 · A P0087 code on your car’s diagnostic system indicates a potential failure of the fuel rail pressure sensor. The sensor monitors fuel rail pressure and relays data to the engine control unit (ECU). The P0087 code activates when a faulty sensor results in …

p0087故障解释为：轨压压力低于调节值。 要完全弄懂这个故障码的全部故障源，我们要首先了解一下轨压传感器的工作原理、 ECU 监测轨压的基本原理，下面几个基础点我们要留意：

When diagnosing the condition above on a common rail diesel vehicle, if no root cause is found after checking all other components and all GFF diagnostic procedures have been performed, it may be necessary to check for metallic particles in the High Pressure Fuel Pump using the service section of this bulletin.

2025年1月31日 · P0087 is an OBD-II trouble code that signals a low fuel pressure condition in the fuel rail or fuel system. Fuel pressure is crucial for maintaining the optimal air-fuel mixture required for efficient combustion within the engine cylinders.

2022年1月31日 · For proper fault isolation, complete all troubleshooting steps in the sequence provided. Step 1. Investigate Related Trouble Codes. codes. One or multiple other codes could have been the cause for this code. Step 2. Fuel System, Low Pressure Checks. Step 3. …

2023年12月23日 · 当车辆的燃油系统油压异常低时，便会触发P0087故障码。 以下是可能导致此故障的原因及其对应的解决方法： 1. 燃油管道破损泄漏. 长时间使用或意外撞击都可能导致燃油管道破损，进而引发泄漏，使油轨压力降低。 拖车至专业4S店进行破损管道的更换是有效的解决方法。 2. 劣质燃油使用导致滤清器堵塞. 不慎加入劣质燃油，其中的杂质会堵塞燃油滤清器，影响正常供油，从而降低油轨压力。 此时，除了更换滤清器外，还需确保未来在大型、正规的加油 …

P0087 is a general OBD-II diagnostic trouble code that indicates a fault within the fuel delivery system. This code is set once the ECM has detected low fuel pressure at the fuel pressure sensor . Low fuel pressure causes the Check Engine Light to trigger by the ECM and a failsafe mode is enacted to prevent damage until repaired.

2015年5月6日 · P0087 - Fuel Rail/System Pressure Too Low. Possible Causes: - Fuel filter plugged or dirty - Fuel supply line restricted - Damaged fuel pump module - Damaged fuel injection pump

2024年12月27日 · Fuel rail pressure too low often shows up as code P0087. It means the fuel system pressure is not where it should be. Keeping the fuel rail pressure right is key for your engine to work well. If the pressure gets too low, it can cause problems like rough idling and misfires. Knowing why and how to fix low fuel rail pressure is important.
