Are you having trouble with your fuel gauge in your 1987 Toyota Pickup? This article will provide you with a detailed wiring diagram and instructions to help you troubleshoot and fix the issue. With the help of this guide, you can easily identify the problem and get your fuel gauge working properly again.
Understanding the Fuel Gauge System
The fuel gauge system in your 1987 Toyota Pickup consists of several components, including the fuel level sensor, wiring, and the gauge itself. The fuel level sensor is located in the fuel tank and sends a signal to the gauge to display the current fuel level.
The wiring that connects these components can become damaged or corroded over time, which can cause the fuel gauge to malfunction. By understanding how the fuel gauge system works, you can easily diagnose and repair any issues that may arise.
Frequently Asked Questions
| Question | Answer |
|---|---|

| How can I diagnose the problem? | You can diagnose the problem by checking the wiring for any damage or corrosion, testing the fuel level sensor, and checking the gauge for proper operation. |
| Can I fix the issue myself? | Yes, with the help of this guide, you can easily diagnose and fix the issue yourself. |
Wiring Diagram
Before you start troubleshooting, it is important to have a wiring diagram to help you identify the different components and connections in the fuel gauge system. Below is a wiring diagram for the 1987 Toyota Pickup fuel gauge system.
| Connector | Wire Color | Description |
|---|---|---|
| CB1 | B | Battery Positive |
| CB1 | W | Ground |
| C11 | G | Fuel Sender Signal |
| C11 | BR | Fuel Level Warning Switch Signal |
| C11 | L | Instrument Cluster – Fuel Gauge Signal |
Diagnosing the Problem
If your fuel gauge is not working properly, follow the steps below to diagnose the issue:
Step 1: Check the Wiring
The first step is to check the wiring for any damage or corrosion. Look for any broken or frayed wires or loose connections. If you find any issues, repair or replace the affected components.
Step 2: Test the Fuel Level Sensor
The next step is to test the fuel level sensor. You can do this by using a multimeter to check the resistance of the sensor. The resistance should change as the fuel level in the tank changes. If the resistance does not change, the sensor may be faulty and will need to be replaced.
Step 3: Check the Gauge
If the wiring and sensor are functioning properly, the next step is to check the gauge itself. You can do this by removing the gauge from the instrument cluster and testing it with a multimeter. The gauge should move in response to changes in resistance. If it does not, the gauge may be faulty and will need to be replaced.
Conclusion
By following the steps outlined in this guide and using the provided wiring diagram, you can easily diagnose and fix any issues with your 1987 Toyota Pickup fuel gauge. Remember to check the wiring, test the fuel level sensor, and check the gauge to identify and resolve any issues.
