Problem Statement

Learn how to diagnose and repair the strong smell of gasoline in your 2010 Volvo XC60 with our step-by-step guide.

Affected Component

fuel system, EVAP system

Symptoms

•Noticeable gasoline odor inside or outside the vehicle.
•Possible fuel leakage under the car.
•Decreased fuel efficiency.
•Check Engine Light (CEL) may be illuminated.

Diagnostic Steps

1
Check for Fuel Leaks: Look under the vehicle for any signs of fuel pooling or wet spots.
2
Inspect Fuel Lines and Connections: Examine the fuel lines leading from the tank to the engine for cracks, wear, or loose connections.
3
Examine the Fuel Tank: Inspect the fuel tank for corrosion or damage.
4
Inspect EVAP Canister: Look for cracks or damage; this component captures fuel vapors.
5
Examine EVAP Hoses: Ensure all hoses connected to the EVAP system are intact and not cracked or disconnected.
6
Scan for Codes: Use an OBD-II scanner to check for any codes related to the fuel system or EVAP system.
7
Check Fuel Trim Values: Analyze long-term and short-term fuel trim values for any irregularities that might indicate a fuel delivery issue.
8
Connect Fuel Pressure Gauge: Attach a fuel pressure gauge to the fuel rail to measure the system's pressure.
9
Compare Readings: Ensure the pressure readings are within the manufacturer’s specifications.

Solution

Solution

Problem Diagnosis: Strong Smell of Gasoline in 2010 Volvo XC60

Tools Required:

OBD-II Scanner
Fuel Pressure Gauge
Basic Hand Tools (screwdrivers, wrenches, etc.)
Safety Goggles and Gloves
Shop Towels or Rags
Flashlight

Repair Instructions:

Step 1: Address any Fuel Leaks

If any fuel leaks are detected:
- Tighten Loose Connections: Use appropriate tools to tighten any loose clamps or fittings.
- Replace Damaged Lines: Cut out any damaged sections of fuel line and replace with new line, ensuring proper fittings.

Step 2: Repair or Replace EVAP Components

If the EVAP canister or hoses are damaged:
- Remove and Replace EVAP Canister: Disconnect the hoses, unbolt the canister from its mount, and replace with a new unit.
- Replace EVAP Hoses: Cut and replace damaged hoses with new, OEM-spec hoses.

Step 3: Solve Fuel Pressure Issues

If fuel pressure is outside specifications:
- Replace Fuel Pump: If the pressure is low, the fuel pump may be failing. Remove the rear seat or access panel, disconnect the battery, relieve fuel pressure, and proceed to replace the fuel pump.
- Replace Fuel Filter: If restricted, replace the fuel filter according to the service manual.

Step 4: Clear Codes and Test Drive

After repairs are completed:
- Clear OBD-II Codes: Use an OBD-II scanner to clear any fault codes.
- Test Drive the Vehicle: Monitor for any return of the gasoline smell and check for any illuminated warning lights.

Final Check:

After the test drive, perform a final visual inspection for any remaining leaks and ensure everything is functioning correctly. If the smell persists, further diagnostics may be necessary to check for less common issues such as injector leaks or faults in the engine management system.

Important Note:

Always prioritize safety when working on fuel systems. Work in a well-ventilated area and keep fire extinguishers handy. If unsure or if the problem persists after DIY efforts, consult a professional technician for assistance.
