As a car expert, I understand how frustrating it can be when your vehicle is not functioning properly. One common issue that car owners face is the P1399 Glow Plug Circuit High Input (Bank #2) error code. This error code indicates that there is a problem with the glow plug circuit in the second bank of cylinders. Fortunately, this is a problem that can be fixed with a few simple steps. In this article, I will provide you with a step-by-step guide on how to fix the P1399 Glow Plug Circuit High Input (Bank #2) error code.
Step 1: Check the Glow Plugs
The first step in fixing the P1399 Glow Plug Circuit High Input (Bank #2) error code is to check the glow plugs. Glow plugs are responsible for heating the air in the combustion chamber, which is necessary for starting the engine. If the glow plugs are not functioning properly, it can cause the engine to misfire and trigger the P1399 error code.
To check the glow plugs, you will need a multimeter. Start by disconnecting the electrical connector from each glow plug and testing the resistance of each plug. The resistance should be between 0.6 and 2.0 ohms. If the resistance is outside of this range, the glow plug needs to be replaced.
Step 2: Check the Wiring
If the glow plugs are functioning properly, the next step is to check the wiring. Start by inspecting the wiring for any signs of damage or corrosion. If the wiring is damaged, it will need to be repaired or replaced.
Next, use a multimeter to test the continuity of the wiring. Start by disconnecting the electrical connector from the glow plug control module and testing the continuity of each wire. If there is no continuity, the wiring needs to be repaired or replaced.
Step 3: Check the Glow Plug Control Module
If the glow plugs and wiring are functioning properly, the next step is to check the glow plug control module. The control module is responsible for controlling the glow plugs and can cause the P1399 error code if it is not functioning properly.
To check the control module, start by disconnecting the electrical connector from the module and testing the resistance of each pin. The resistance should be between 0.1 and 1.0 ohms. If the resistance is outside of this range, the control module needs to be replaced.
Step 4: Replace the Faulty Component
Once you have identified the faulty component, it needs to be replaced. If it is a glow plug, simply remove the old plug and replace it with a new one. If it is wiring or the control module, it will need to be repaired or replaced.
Conclusion
Fixing the P1399 Glow Plug Circuit High Input (Bank #2) error code is a simple process that can be done with a few basic tools. By following the steps outlined in this article, you can identify and fix the problem quickly and easily. Remember to always use caution when working on your vehicle and consult a professional if you are unsure about any aspect of the repair process.
