Fuel System Leak Detected Large Leak
A code exists for a large leak, small leak, and very small leak. There is a range of fuel leakage programmed into the Powertrain Control Module (PCM) by the manufacturer to determine which code will be stored based on the amount of leakage.
All of these issues could trigger a large fuel leak code:
Running out of fuel at a very fast rate
Extremely poor fuel economy
The risk of a fire
Fuel pressure decrease (could cause the engine to run poorly, further decreasing fuel economy)
The mechanic will start by visually inspecting the fuel system, searching primarily for the leak. Since the leak is considered a large leak, it should be fairly easy to locate.
Once the source of the fuel leak has been found, the mechanic will repair or replace the part that is causing the large fuel leak.
Considering that the issue at hand is a large fuel leak, it would be quite difficult to make a mistake during diagnosis. This issue is as simple as locating the fuel leak and having it repaired.
The P0093 code is very serious. Having this code stored in your Powertrain Control Module can be a safety issue. With this code in the system, it is a safety hazard because a fire can be caused by this. It is very important to have the fuel leak located and repaired as soon as possible.
Any part of the fuel system can cause this code. Some of the parts that could be replaced to repair this issue would include:
It is not advisable to drive your 2012 Chevrolet Colorado 4wd-crew-cab very much with a P0093 code stored in the PCM. A large fuel leak is one of the most major safety concerns that a 2012 Chevrolet Colorado 4wd-crew-cab could possibly have. Someone driving by who tosses a cigarette out the window could be oblivious to your large fuel leak and cause personal injury or death.
