Fuel System Leak - Small Leak Detected
The P0094 code is set in a vehicle’s Powertrain Control Module (PCM) when it detects a small leak in the fuel system. It is most common on vehicles with diesel engines.
Inspects the fuel system for leaks
Repairs any leaks found
If no leaks are found in the fuel system:
If fuel pressure is lower than manufacturer-specified pressure:
Checking for leaks and, after not finding any leaks, replacing the fuel pressure regulator. This part is a common cause of this issue, however is is always best to know for sure that a part is faulty by testing it before replacing anything.
The P0094 code is not as serious as a P0093 code, due to the fact that the leak is smaller. However, considering that a fuel leak is still possible, the risk of a fire is also possible, which can become a very serious safety issue and could cause injury to the driver and passengers.
Just because this code says that a “small leak” has been detected in the fuel system does not mean that a leak actually exists. This code is set when the PCM sees a noticeable loss in fuel pressure. If the fuel pressure sensor or its circuitry are damaged, or the fuel pressure regulator, fuel pump, or fuel filter are faulty, this can cause a decrease in fuel pressure and therefore cause a P0094 code.
