Question

I got the engine code P1188 on my Hyundai, what is the most likely cause of the code?

Answer 1

Hi there

This code means fuel pressure monitoring leakage.

This means the computer sees a problem with a leak in the fuel system. This could be a bad fuel filter, leaking fuel injector,fuel pressure regulator, fuel pump or an issue with the fuel rail pressure sensor.
