How To Repair P0104 Code

Before starting let's see P0104 repairing process steps:

  • Qualified technicians will begin by using a scan tool to access P0104 code stored in the ECU.
  • Technicians will note P0104 code present and any freeze frame data associated with them.
  • After all, if you sure the engine trouble is finished, the code will be cleared.

As you idle at a light or before positioning your vehicle in gear and you see that your engine is starting to create strange sounds, switch your oil filter and also inspect the pressure regulator to attempt and adjust the error. If you struggle to start your vehicle and notice it fails to turn over right away, it can also indicate a defective fuel pressure regulator.

Make sure you indurate frame the data. Any canons that were set previous to the P0104 code will have to be sorted first, as they may have been the reason for the law to set in the first place. It's always good to rule that out.

The coming step is to run a introductory examination of all the electrical circuits, connectors, wiring etc for damages similar as becks, erosion, fraudulent legs etc. All of these will have to be repaired or replaced. After that's sorted, clear the canons and go on a test drive to see if it resets. In case it resets, you'll have to continue your opinion. Depending on your vehicle you may have a vacuum operated selector or a vacuum solenoid if it's electrically actuated. In the case of the former, a hand held vacuum pump will have to be used to testit.The purpose is to see if the internal stopcock is getting turned by the selector, motor or solenoid. In order to do this, a command can be transferred to the system with scanner or by driving the vehicle under the special conditions that will spark the system. While this is passing keep an eye on the checkup tool data for the result.
