why does my Toyota Tacoma N300 (2016-Present) reduce power in eco mode

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the engine is cool.
• Disconnect the negative battery terminal to avoid electrical shorts.

2. Inspect Air Intake System

• Remove the air intake duct from the throttle body.
• Inspect the air filter for dirt and debris; replace if necessary (Part: Air filter).
• Check the intake duct for any cracks or leaks and replace if needed.

3. Clean Throttle Body

• Remove the throttle body from the intake manifold (tools: socket set).
• Use throttle body cleaner and a soft cloth to clean the throttle plate and inside of the throttle body.
• Reinstall the throttle body and torque to manufacturer specifications (typically around 10-15 ft-lbs).

4. Check Fuel Delivery System

• Attach a fuel pressure gauge to the fuel rail to measure pressure while the engine is running.
• Compare the reading to the manufacturer’s specifications (usually around 50-60 psi for Tacoma).
• Replace the fuel filter if pressure is below specifications (Parts: Fuel filter) and check the fuel pump for proper operation.

5. Reconnect Battery and Test

• Reconnect the negative battery terminal.
• Start the engine and let it idle for a few minutes to ensure all systems are operational.
• Take the vehicle for a test drive, monitoring for power delivery and responsiveness.
