How to Fix P1287 Excessive Injection Control Pressure

Introduction

If you’re experiencing P1287 Excessive Injection Control Pressure, you’re not alone. This is a common issue that many car owners face. The good news is that it’s fixable, and you don’t need to be a car expert to do it. In this article, we’ll provide you with step-by-step instructions on how to fix P1287 Excessive Injection Control Pressure.

What is P1287 Excessive Injection Control Pressure?

P1287 Excessive Injection Control Pressure is a diagnostic trouble code (DTC) that indicates a problem with the high-pressure oil system in your car’s engine. This system is responsible for supplying oil to the injectors, which in turn, inject fuel into the engine. When there’s too much pressure in the system, it can cause a range of issues, including rough idling, poor acceleration, and even engine failure.

Step-by-Step Guide to Fixing P1287 Excessive Injection Control Pressure

Step 1: Check the Oil Level

The first thing you should do is check the oil level in your car’s engine. Low oil levels can cause the high-pressure oil system to malfunction, leading to P1287 Excessive Injection Control Pressure. If the oil level is low, add more oil and see if the problem goes away.

Step 2: Check the Oil Pressure Sensor

The next step is to check the oil pressure sensor. This sensor is responsible for monitoring the oil pressure in the engine and sending signals to the car’s computer. If the sensor is faulty, it can cause P1287 Excessive Injection Control Pressure. Use a multimeter to test the sensor and replace it if necessary.

Step 3: Check the IPR Valve

The IPR (Injection Pressure Regulator) valve is another component that can cause P1287 Excessive Injection Control Pressure. This valve regulates the pressure in the high-pressure oil system. If it’s faulty, it can cause the pressure to be too high, leading to the DTC. Use a multimeter to test the valve and replace it if necessary.

Step 4: Check the High-Pressure Oil Pump

The high-pressure oil pump is responsible for supplying oil to the injectors. If it’s not working correctly, it can cause P1287 Excessive Injection Control Pressure. Use a pressure gauge to test the pump and replace it if necessary.

Useful Tips

– Always wear protective gear when working on your car’s engine.
– Use a repair manual or online resources to help you with the repair process.
– Take your time and be patient. Rushing can lead to mistakes and further damage to your car.
