how to troubleshoot loss of power in my Ford F-150 13th Generation (2015-2020)

Solution

1. Preparation

• Tools Required: OBD-II scanner, Fuel pressure gauge, Socket set, Torque wrench, Screwdrivers
• Verify that the vehicle is parked on a level surface and the engine is cool. Disconnect the battery to ensure safety during repairs.

2. Air Filter Inspection and Replacement

• Remove the air filter housing cover using a screwdriver.
• Take out the existing air filter and inspect it for dirt and debris.
• If dirty, replace it with a new air filter (ensure it matches OEM specifications).
• Reassemble the air filter housing cover and tighten screws to manufacturer torque specifications.

3. Fuel System Check

• Connect the fuel pressure gauge to the fuel rail.
• Turn the ignition key to the "On" position (do not start the engine) to check fuel pressure.
• Compare the reading to Ford's specifications (typically around 30-65 psi depending on the engine). If pressure is low, check for fuel pump functionality.
• If required, replace the fuel filter and/or fuel pump, following the appropriate service manual for removal and installation.

4. Ignition System Inspection

• Remove the ignition coils from their respective spark plugs using a socket set.
• Inspect the spark plugs for wear (replace if necessary) and ensure proper gap settings.
• Test ignition coils for resistance using a multimeter, replacing any that are out of spec.

5. Throttle Body Cleaning

• Remove the throttle body from the intake manifold by loosening the mounting bolts with a socket set.
• Use throttle body cleaner to remove carbon deposits from the throttle plate and body.
• Reinstall the throttle body and torque the bolts to specifications.

6. Exhaust System Inspection

• Visually inspect the exhaust system for any blockages, such as a damaged catalytic converter.
• Perform a backpressure test to ensure the exhaust is flowing properly.
• Replace any damaged components as needed.
