Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, fuel pressure gauge.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery before working on electrical systems.

2. Address Error Codes

Use the OBD-II scanner to clear any error codes after noting them down.
If codes reappear after clearing, focus on the specific codes to guide repairs.

3. Inspect and Clean Air Intake

Remove the air intake hose using a socket set.
Inspect the air filter for dirt and replace if necessary.
Clean the throttle body with throttle body cleaner to remove carbon buildup.

4. Check Fuel System

Fuel Pressure Measurement:
- Connect a fuel pressure gauge to the fuel rail.
- Turn the ignition to the “ON” position (do not start the engine) to check pressure readings against specifications.
- Replace the fuel filter if pressure is below specs or if it is clogged.

5. Inspect Spark Plugs and Ignition Coils

Remove the spark plug covers and disconnect ignition coils.
Inspect spark plugs for wear or fouling; replace if necessary.
Test ignition coils using a multimeter for resistance; replace any faulty coils.

6. Test Throttle Position Sensor

Disconnect the TPS and connect the multimeter to the appropriate terminals.
Measure the resistance while moving the throttle plate; ensure it varies smoothly and matches specifications.
Replace the TPS if it does not meet specifications.
