Problem Statement

Learn how to diagnose and repair the strong gasoline smell issue in your 2012 Volvo XC60. Follow our step-by-step guide for effective troubleshooting and solutions.

Affected Component

fuel system

Symptoms

•Noticeable gasoline odor inside or around the vehicle.
•Possible fuel leakage under the vehicle.
•Check Engine Light may be illuminated.
•Decreased fuel economy (in some cases).
•Possible symptoms of fuel vapor in cabin (headaches, nausea).

Diagnostic Steps

1
Visual Inspection: Check for any visible signs of fuel leaks under the vehicle, especially around the fuel tank, fuel lines, and fuel injectors. Inspect the fuel filler cap and ensure it is properly secured and not damaged. Examine the area around the fuel pump and fuel filter for any signs of leaks.
2
Fuel System Pressure Test: Use a fuel pressure gauge to check the fuel system pressure. Connect the gauge to the fuel rail service port and turn the ignition to the 'ON' position (do not start the engine). Note the pressure reading; it should be within manufacturer specifications (check the service manual for exact figures).
3
Check for Fault Codes: Use an OBD-II scanner to check for any stored trouble codes related to the fuel system. Pay attention to codes indicating evaporative emissions control system issues (e.g., P0440, P0441).
4
Inspect Evaporative Emissions System: Check the EVAP canister for any cracks or damage. Inspect the hoses connected to the EVAP system for leaks or loose connections. Perform a smoke test if necessary to identify any leaks in the EVAP system.

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

•Visual inspection tools (flashlight)
•OBD-II scanner
•Fuel pressure gauge
•Smoke machine (for EVAP system testing)
•Basic hand tools (screwdrivers, wrenches, pliers)
•Safety glasses and gloves

Solution

Problem: Strong Gasoline Smell in 2012 Volvo XC60

Tools Required:

Visual inspection tools (flashlight)
OBD-II scanner
Fuel pressure gauge
Smoke machine (for EVAP system testing)
Basic hand tools (screwdrivers, wrenches, pliers)
Safety glasses and gloves

Repair Instructions:

1. Fuel Leak Repair:

If a leak is detected:
- Replace any damaged fuel lines or components.
- Tighten any loose connections.
- Replace the fuel filler cap if it is cracked or not sealing properly.

2. EVAP System Repair:

If the EVAP canister is damaged, replace it by:
- Disconnecting the battery.
- Removing mounting bolts and disconnecting hoses.
- Installing the new canister and reattaching hoses.
- Reconnect the battery.

3. Fuel Pressure Issues:

If fuel pressure is outside specifications:
- Replace the fuel filter if clogged.
- If the fuel pump is faulty, replace it by:
  - Relieving the fuel system pressure.
  - Disconnecting the battery.
  - Removing the fuel pump access cover (usually located in the trunk).
  - Disconnecting the fuel lines and electrical connectors.
  - Removing the fuel pump assembly and replacing the pump.
  - Reinstalling all components in reverse order.

4. Clearing Codes:

After repairs, clear any trouble codes using the OBD-II scanner.
Test drive the vehicle and monitor for any reoccurrence of the gasoline smell.

Final Check:

After performing the repairs, conduct a thorough inspection once again to ensure that there are no more gasoline odors. Take the vehicle for a test drive to confirm that the issue has been resolved. If the smell persists, further investigation may be required, potentially involving professional diagnostics.
