Engine Control System
The engine control system in your 2001 Tacoma is responsible for managing the fuel and air mixture, ignition timing, and other critical aspects of engine performance. To do this, it relies on a complex network of sensors, switches, and relays, all of which are connected via the wiring harness.
Overview
The engine control system is comprised of several components, including the engine control module (ECM), mass airflow sensor (MAF), oxygen (O2) sensors, and more. These components work together to regulate the fuel and air entering the engine, as well as the ignition timing and other aspects of engine performance.
To diagnose engine control issues, you’ll need to refer to the wiring diagram for your 2001 Tacoma. This will help you identify which components are faulty, and where the issue might be located.

Starting System
The starting system in your 2001 Tacoma is responsible for cranking the engine and getting it started. It relies on several components, including the battery, starter motor, ignition switch, and more. Like the engine control system, the starting system is connected via the wiring harness, which allows electricity to flow between components.
Overview
The starting system is composed of several components, including the battery, starter motor, starter relay, and ignition switch. When you turn the key, the ignition switch sends an electrical signal to the starter relay, which activates the starter motor. The starter motor then cranks the engine, which helps it start.
If you’re experiencing issues with your starting system, it’s important to refer to the wiring diagram for your 2001 Tacoma. This will help you identify which components are faulty and where the issue might be located.
