As a car expert, I understand how frustrating it can be when your vehicle is not functioning properly. One common issue that many car owners face is the P1396 Glow Plug Circuit Low Input (Bank #1) error code. This error code indicates that there is a problem with the glow plug circuit in the engine’s first bank. Fortunately, this issue can be resolved with a few simple steps. In this article, I will provide you with a step-by-step guide on how to fix the P1396 Glow Plug Circuit Low Input (Bank #1) error code.
Step 1: Check the Glow Plugs
The first step in fixing the P1396 error code is to check the glow plugs. Glow plugs are responsible for heating the engine’s combustion chamber, which is essential for starting the engine in cold weather. If the glow plugs are faulty, they will not heat up properly, causing the engine to struggle to start. To check the glow plugs, you will need a multimeter. Follow these steps:
1. Turn off the engine and let it cool down.
2. Locate the glow plugs. They are usually located near the engine’s intake manifold.
3. Disconnect the electrical connector from each glow plug.
4. Set your multimeter to the ohms setting.
5. Touch one probe of the multimeter to the glow plug’s terminal and the other probe to the engine’s ground.
6. Check the reading on the multimeter. If the reading is higher than the manufacturer’s specifications, the glow plug is faulty and needs to be replaced.
Step 2: Check the Glow Plug Relay
If the glow plugs are functioning correctly, the next step is to check the glow plug relay. The glow plug relay is responsible for sending power to the glow plugs. If the relay is faulty, the glow plugs will not receive power, causing the engine to struggle to start. To check the glow plug relay, follow these steps:
1. Turn off the engine and let it cool down.
2. Locate the glow plug relay. It is usually located in the engine compartment, near the battery.
3. Disconnect the electrical connector from the relay.
4. Set your multimeter to the ohms setting.
5. Touch one probe of the multimeter to the relay’s terminal and the other probe to the engine’s ground.
6. Check the reading on the multimeter. If the reading is higher than the manufacturer’s specifications, the relay is faulty and needs to be replaced.
Step 3: Check the Wiring
If the glow plugs and the glow plug relay are functioning correctly, the next step is to check the wiring. Faulty wiring can cause the glow plug circuit to malfunction, resulting in the P1396 error code. To check the wiring, follow these steps:
1. Turn off the engine and let it cool down.
2. Inspect the wiring for any signs of damage, such as frayed wires or loose connections.
3. Use a multimeter to check the continuity of the wiring. Touch one probe of the multimeter to one end of the wire and the other probe to the other end of the wire. If the multimeter shows no continuity, the wire is faulty and needs to be replaced.
Step 4: Replace Faulty Components
Once you have identified the faulty component, it is time to replace it. You can purchase replacement glow plugs, glow plug relays, and wiring from your local auto parts store or online. Follow the manufacturer’s instructions for installing the new components.
Conclusion
The P1396 Glow Plug Circuit Low Input (Bank #1) error code can be frustrating, but it is a relatively easy fix. 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.
