Hello everyone, in this video, we’ll be talking about a Ford F-150 truck that came into our shop with a 2005 model year and a 4.2-liter V6 engine. It’s uncommon to see these trucks with a V6 engine, as they usually come with V8s. The reason for the truck’s visit to our shop is due to a faulty fuel pressure sensor on the rail, which triggers the OBD2 code P0193, leading to fueling issues.
The feedback from this sensor is crucial for the ECU to control the fuel pump and maintain the correct fuel pressure. When this sensor malfunctions, the truck sets off additional fueling codes and runs poorly. Fortunately, replacing the sensor is relatively straightforward, despite conflicting information available online.
The fuel pressure sensor can be accessed and replaced with just a few tools: a ratchet wrench, a short extension, and an eight-millimeter socket. It is located behind the rear end of the intake plenum and can be reached without removing the entire intake plenum.
Simply locate the electrical connector for the fuel pressure sensor, remove the two eight-millimeter bolts, disconnect the vacuum reference line, and the sensor can be replaced in around fifteen to twenty minutes.
In our case, replacing the fuel pressure sensor resolved the issue, and the truck ran smoothly afterward. We hope this information helps if you encounter a similar problem. Feel free to leave any questions related to this topic in the comments section. Thank you for watching!
What is the issue with the truck?
The truck has a fuel pressure sensor on the rail that is causing a P0193 OBD2 code, affecting the fuel pressure and triggering additional fueling codes P0171 and P0174.
How can the issue be resolved?
The fuel pressure sensor can be accessed and replaced with an 8mm socket, a little ratchet wrench, and a short extension. The process can be completed in about fifteen to twenty minutes.
Did replacing the fuel pressure sensor solve the problem?
Yes, replacing the fuel pressure sensor with a new one resolved the issue, causing the codes to disappear and the truck to run properly.
