Problem Statement

Learn how to diagnose and fix engine hesitations in Renault Clio V (2019-Present). Step-by-step guide with symptoms, diagnostic steps, and repair instructions.

Affected Component

Engine

Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

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

Symptoms

•Engine stalling during acceleration
•Rough idling when the engine is cold
•Decreased throttle response
•Check engine light illuminated
•Poor fuel efficiency
•Unusual engine noises (e.g., sputtering or misfiring)

Diagnostic Steps

1
Scan for error codes using an OBD-II scanner to identify potential fault codes.
2
Inspect the air intake system for blockages or leaks (including air filter and intake hoses).
3
Check the fuel system for proper pressure using a fuel pressure gauge.
4
Examine the ignition system components (spark plugs, wires, and coils) for wear or damage.
5
Inspect the exhaust system for restrictions or leaks that may impact engine performance.
6
Test the throttle position sensor (TPS) for correct voltage output and operation.

Solution

💡 Expert Tip

For complex repairs like this, consider taking photos at each step. This helps if you need to reverse a step or consult with a mechanic. Also, keep all removed parts organized - you may need to reference them during reassembly.

Verification

After completing the repair, verify that the issue has been resolved:

✓Test the affected component to ensure it functions correctly
✓Check for any error codes or warning lights
✓Monitor the vehicle for a few days to ensure the issue does not recur

Prevention Tips

To prevent this issue from occurring again:

•Follow the manufacturer's recommended maintenance schedule
•Address warning signs early before they develop into major issues
•Use quality parts and fluids recommended for your vehicle
•Keep detailed records of all repairs and maintenance

Tools & Equipment Required

•OBD-II scanner
•Fuel pressure gauge
•Socket set
•Multimeter

Parts Required

•Air filter
•Spark plugs
•Ignition coils (if necessary)
•Throttle position sensor (if necessary)

Solution

1. Preparation

Tools Required: OBD-II scanner, fuel pressure gauge, socket set, multimeter.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Air Filter

Remove the air filter housing cover using a socket set.
Take out the old air filter and check for dirt or blockages.
Install a new air filter that meets OEM specifications.
Reassemble the air filter housing cover securely.

3. Fuel System Inspection

Connect the fuel pressure gauge to the fuel rail test port.
Start the engine and monitor the fuel pressure; it should meet the manufacturer’s specifications.
If pressure is low, check the fuel pump relay and fuel filter.
Replace any faulty components as needed.

4. Ignition System Repair

Remove the spark plug wires using a socket set and inspect for wear or corrosion.
Replace worn spark plugs with new ones that match the manufacturer's specifications.
Test ignition coils using a multimeter; replace any faulty coils.

5. Throttle Position Sensor (TPS) Testing

Locate the TPS on the throttle body and disconnect the electrical connector.
Use a multimeter to test the voltage output while moving the throttle plate.
If the readings are outside of specified range, replace the TPS.
