Affected Component

Engine

Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the battery before working on electrical systems.
•Allow engine to cool before servicing components.

Symptoms

•Check engine light illuminated
•Engine hesitates during acceleration
•Reduced power when climbing hills
•Increased fuel consumption
•Rough engine performance at higher RPMs

Diagnostic Steps

Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Inspect and Replace Air Filter

Remove the air cleaner cover using a socket set.
Take out the old air filter and inspect for dirt or damage.
Install a new, clean air filter.
Reassemble the air cleaner cover.

3. Fuel System Check

Use a fuel pressure gauge to check the fuel pump pressure at the fuel rail.
- If pressure is low, replace the fuel pump.
Change the fuel filter if it is clogged or hasn't been replaced in accordance with maintenance intervals.

4. Spark Plug Replacement

Remove the ignition coils by unscrewing them with a socket set.
Extract the spark plugs using a spark plug socket.
Inspect and replace with new spark plugs according to the manufacturer's specifications.
Reinstall ignition coils and ensure they are seated securely.

5. Throttle Position Sensor Testing

Locate the throttle position sensor and disconnect its electrical connector.
Use a multimeter to check for proper voltage output while manually moving the throttle plate.
If the TPS is faulty, replace it and reconnect the electrical connector.

6. Exhaust System Inspection

Visually inspect the exhaust system for any visible cracks or holes.
Check for any blockages in the catalytic converter or muffler.
If there are blockages, replace the affected components.
