In this article, we will explore the concept of the AM2 fuse in Toyota vehicles. The AM2 fuse plays an important role in the ignition system of Toyota cars, ensuring proper functioning and preventing electrical faults.
Understanding EFI (Electronic Fuel Injection)
Before diving into the details of the AM2 fuse, let’s first understand the EFI system. EFI refers to the electronic throttle. It is responsible for controlling and managing the fuel injection process in a Toyota vehicle.
The EFI system judges the idle state through the signal of the brake light switch and the brake pedal switch. It also turns off the cruise control, lights up the EPC (Electronic Power Control) light, and stores fault codes in the fault memory.

Role of the AM2 Fuse
The AM2 fuse is an important component of the ignition system in Toyota vehicles. This fuse is essentially a switched ignition power source that feeds many systems in the car. When the ignition switch is turned to the “ON” position, the AM2 fuse provides power to various components.
One of the critical functions of the AM2 fuse is to provide the starter with an “open starter relay and start the car” signal. When you turn the ignition switch to the “START” position, the AM2 fuse activates the starter relay, allowing the car to start. Once the car is started and you release the ignition switch back to the “ON” position, the AM2 fuse continues to power other systems in the vehicle.
It is important to note that the AM2 fuse only goes through the ignition switch and powers the coil and fuel injectors. In case of any faults or issues with the AM2 fuse, it can affect the overall functioning of the ignition system and result in problems starting or running the vehicle.
Signs of AM2 Fuse Issues
If you suspect that there might be an issue with the AM2 fuse in your Toyota vehicle, there are some signs you can look out for. These signs include:
- Car not starting
- No clicking sound when turning the ignition switch
- Electrical components not functioning properly
If you experience any of these symptoms, it is recommended to have your vehicle inspected by a qualified technician to identify and resolve any AM2 fuse-related problems.

Frequently Asked Questions On What Is Am2 Fuse Toyota
What Is Am1 And Am2 On Ignition Switch?
AM1 and AM2 on the ignition switch refer to two specific circuits. AM1 is the circuit that provides power to various components such as the starter, fuel injectors, and ignition coil. AM2, on the other hand, supplies power to the antilock control module/pump in the engine compartment.
These circuits play a crucial role in the functioning of the ignition system and other related systems in a vehicle.
What Does Am1 Fuse Stand For?
The AM1 fuse stands for Accessory Meter 1 fuse. It is a fuse that provides power to various electrical components in the vehicle, such as the ignition system, fuel injectors, and coil. This fuse is important for the proper functioning of these systems.
What Is Efi In Fuse Box?
EFI in the fuse box refers to the electronic throttle. It monitors the idle state using signals from the brake light switch and brake pedal switch. It also disables cruise control, activates the EPC, and records fault codes. The EFI fuse provides the starter with a signal to start the car.
It is a crucial part of the ignition system and powers various components such as the coil and fuel injectors.
What Is An Am2 Fuse In Toyota?
An AM2 fuse in Toyota is a type of fuse that is part of the ignition system. It powers the coil and fuel injectors in the multiport fuel injection system/sequential multiport fuel injection system.
How Does An Efi Fuse Work?
An EFI fuse, also known as an Electronic Fuel Injection fuse, provides the starter with an “open starter relay and start the car” signal. It plays a crucial role in starting the engine by supplying power to the starter.
Conclusion
The AM2 fuse holds a crucial role in the ignition system of Toyota vehicles. It provides the necessary power to various components and ensures proper functioning of the ignition system. If you encounter any issues with your Toyota’s starting or running, it’s always wise to have a professional inspect the AM2 fuse and address any problems to maintain optimal performance of your vehicle.
