The P02C5 fault code pertains to Cylinder 11 Injector Leaking. This code typically indicates that there is a fuel leak in the fuel injector for cylinder 11. The fuel injector is responsible for delivering fuel into the combustion chamber of the engine at the appropriate time.

When the fuel injector is leaking, it can cause several issues. Firstly, it can lead to a loss of fuel pressure, which can result in poor engine performance, misfires, and reduced fuel efficiency. Secondly, the leaking fuel can create a potential fire hazard, as fuel leaks can cause fuel to come into contact with hot engine components or electrical connections.

To fix this issue, the first step is to locate and inspect the fuel injector for cylinder 11. It is important to check for any signs of fuel leaks, such as visible fuel drips, wetness around the injector, or a strong fuel smell. If a leak is detected, the fuel injector may need to be replaced.

In some cases, the leak may be caused by a faulty fuel injector seal or O-ring. In such instances, replacing the seal or O-ring may resolve the leak without having to replace the entire fuel injector. However, if the injector itself is damaged or faulty, it will need to be replaced.

It is crucial to address this issue promptly to prevent any further damage or safety risks. If you encounter the P02C5 fault code or suspect a fuel leak in the injector for cylinder 11, it is recommended to have your vehicle inspected and repaired by a qualified mechanic or technician. They will have the necessary tools and expertise to diagnose the issue accurately and ensure a proper repair.
