26 | EXHAUST SULPHUR SMELL
--- | ---
DESCRIPTION | Rotten egg smell (sulphur) from exhaust
POSSIBLE CAUSE | • Electrical connectors are disconnected or connected poorly • Charcoal canister malfunction • Vacuum lines are disconnected or connected improperly. • Improper fuel pressure • Poor fuel quality Warning The following troubleshooting flow chart contains fuel system diagnosis and repair procedures. Read following warnings before servicing fuel system: • Fuel vapor is hazardous. It can easily ignite, causing serious injury and damage. Always keep sparks and flames away from fuel. • Fuel line spills and leakage are dangerous. Fuel can ignite and cause serious injuries or death and damage. Fuel can also irritate skin and eyes. To prevent this, always complete "BEFORE REPAIR PROCEDURE" and "AFTER REPAIR PROCEDURE" described in this manual. (See BEFORE SERVICE PRECAUTION [L3 Turbo].) (See AFTER SERVICE PRECAUTION [L3 Turbo].) Caution • Disconnecting/connecting the quick release connector without cleaning it may possibly cause damage to the fuel pipe and quick release connector.

Diagnostic procedure

STEP | INSPECTION | RESULTS | ACTION
--- | --- | --- | ---
1 | Are any driveability or exhaust smoke concerns present? | Yes | Go to the appropriate flow chart.
No | Go to the next step.
2 | Inspect for the following: • Electrical connections • Vacuum lines • Fuel quality Are all items normal? | Yes | Go to the next step.
No | Service if necessary. Repeat Step 2.
3 | Connect the WDS or equivalent to the DLC-2. Turn the ignition switch to the ON position (Engine off). Retrieve any DTCs. Are there any DTCs displayed? | Yes | DTC is displayed: Go to the appropriate DTC test.
No | No DTC is displayed: Go to the next step.
4 | Access and monitor FUEL_PRES PID. Is the FUEL_PRES PID value within the specified? (See Using the WDS or Equivalent.) | Yes | Go to Step 8.
No | Go to the next step.
5 | Is vehicle accelerate performance normally? | Yes | Go to the next step.
No | Go to Step 7.
6 | Inspect the fuel pressure sensor. (See FUEL PRESSURE SENSOR INSPECTION [L3 Turbo].) Is the fuel pressure sensor normal? | Yes | Go to Step 8.
No | Go to the next step.
7 | Replace the high pressure fuel pump. Monitor FUEL_PRES PID. Is the FUEL_PRES PID value within the specified? (See Using the WDS or Equivalent.) | Yes | Troubleshooting is completed. Go to Step 9.
No | Go to the next step.
8 | Inspect the charcoal canister for fuel saturation. Is excess amount of liquid fuel present in canister? | Yes | Replace the charcoal canister.
No | Inspect the fuel tank vent system. If fuel tank vent system is normal, suggest trying a different brand since sulfur content can vary in different fuels. If fuel tank vent system is not normal, repair or replace the malfunctioning parts.
9 | Verify test results. • If normal, return to the diagnostic index to service any additional symptoms. • If a malfunction remains, inspect the related Service Bulletins and/or On-line Repair Information and perform the repair or diagnosis. - If the vehicle is repaired, troubleshooting is completed. - If the vehicle is not repaired or additional diagnostic information is not available, reprogram the PCM if a later calibration is available. Retest.le. Retest.
