The Toyota 4age engine is a highly popular engine in the automotive world. It is known for its reliability, high performance, and ease of modification. One of the key components of this engine is the distributor. In this article, we will discuss the wiring diagram for the 4age distributor, along with some FAQs and tables.
What is a Distributor?
A distributor is a device that distributes high voltage electric current to the spark plugs in an internal combustion engine. It is responsible for delivering the right amount of electricity at the right time to the spark plugs to create a spark and ignite the fuel in the engine. This process is what makes the engine run.
The distributor consists of a rotor, cap, and a series of contacts. As the rotor spins, it makes contact with the contacts in the cap, sending high voltage electricity to the spark plugs.
The Wiring Diagram for 4age Distributor
The wiring diagram for the 4age distributor consists of six wires. These wires are color-coded and play a specific role in delivering electricity to the spark plugs. Here is a breakdown of the wiring diagram:
| Wire Color | Function |
|---|---|
| Black/Yellow | Distributor Signal |
| Black | Distributor Ground |
| Green/Red | Igniter Signal |
| Green/Yellow | Igniter Ground |
| Blue/Black | Cylinder Number 1 Signal |
| Blue/Yellow | Cylinder Number 2 Signal |
Wire Function
Let’s take a closer look at each of the wire functions:
Black/Yellow
The black/yellow wire is the distributor signal wire. It sends signals to the ECU about the position of the distributor rotor. This information is used by the ECU to adjust the timing of the engine.
Black
The black wire is the distributor ground wire. It provides a path for the high voltage electricity to return to the distributor.
Green/Red
The green/red wire is the igniter signal wire. It sends signals to the igniter about when to fire the spark plugs. The igniter then sends high voltage electricity to the spark plug through the distributor.
Green/Yellow
The green/yellow wire is the igniter ground wire. It provides a path for the high voltage electricity to return to the igniter.
Blue/Black
The blue/black wire is the signal wire for cylinder number 1. It sends signals to the ECU about the position of cylinder number 1. This information is used by the ECU to adjust the timing of the engine.
Blue/Yellow
The blue/yellow wire is the signal wire for cylinder number 2. It sends signals to the ECU about the position of cylinder number 2. This information is used by the ECU to adjust the timing of the engine.
FAQs
Q: What happens if the distributor wiring is incorrect?
If the distributor wiring is incorrect, the engine may not start, or it may run poorly. It is important to follow the wiring diagram and make sure each wire is connected to the correct terminal.
Q: Can the distributor be modified for better performance?
Yes, the distributor can be modified for better performance. This can include modifying the advance curve, installing a high-performance cap and rotor, and upgrading the contacts to handle more electricity.
Q: How often should the distributor cap and rotor be replaced?
The distributor cap and rotor should be replaced every 30,000 miles or as needed. They can wear out over time and cause poor engine performance.
Conclusion
The 4age distributor wiring diagram is a crucial component of the engine’s ignition system. By understanding how each wire functions, you can diagnose problems and modify the distributor for better performance. Follow the wiring diagram and make sure each wire is connected to the correct terminal. If you have any questions or need help, consult a professional mechanic.
