02-21-6 DRIVEABILITY - EXCESSIVE SULFUR SMELL FROM EXHAUST
EXHAUST - EXCESSIVE SULFUR SMELL FROM EXHAUST

Publication Date: October 15, 2002

FORD: 2001-2002 EXPLORER SPORT
2002 EXPLORER SPORT TRAC
2002-2003 EXPLORER
MERCURY: 2002-2003 MOUNTAINEER


Article 02-16-6 is being republished in its entirety to update the Service Procedure and model years.

ISSUE:
Some vehicles may exhibit excessive sulfur smell from the exhaust under certain drive modes. This may be due to the highly active state of a new catalyst, calibration factors, underbody catalyst temperature, and amount of sulfur present in the fuel.

ACTION:
Identify year, model, and build date to identify appropriate service procedure. For applications that require installing exhaust wrap, use good quality stainless steel worm-drive hose clamps for best longevity, similar to what would commonly be used for exhaust heat shield rattle issues.

SERVICE PROCEDURE

2002-2003 4 DOOR EXPLORER/MOUNTAINEER 4.0L

Vehicles Built 1/14/02 Through 12/02/2002

At latest level for engine calibration.

Install Exhaust wrap on the pipes between the light-off and the underbody catalyst referring to the instruction sheet in the kit.
Refer to Drive Sequence heading to purge stored sulfur from catalyst.
See Contributing Factors heading for additional information.
NOTE: CONVERTER REPLACEMENT OR RECALIBRATION IS NOT NECESSARY.



Vehicles Built Before 1/14/02

Verify that WDS is at the latest level, B21.0 or higher.
Reprogram the PCM with the latest calibration.
Install Exhaust wrap on the pipes between the light-off and the underbody catalyst referring to the instruction sheet in the kit.
Refer to Drive Sequence heading to purge stored sulfur from catalyst.
See Contributing Factors Heading for additional information.
NOTE: DO NOT REPLACE THE CONVERTER.



2002-2003 4 DOOR EXPLORER/MOUNTAINEER 4.6L

Vehicles Built Prior To 12/02/2002

Install Exhaust wrap on the pipes between the light-off and the underbody catalyst referring to the instruction sheet in the kit.
Refer to Drive Sequence heading to purge stored sulfur from catalyst.
See Contributing Factors Heading for additional information.
NOTE: CONVERTER REPLACEMENT OR RECALIBRATION IS NOT NECESSARY.



2001-2002 2 DOOR EXPLORER SPORT 4.0L

7/24/00 Through 3/4/02 With 5R55E Transmission

Refer to 2001/2002 Explorer Sport/Sport Trac Workshop Manual, Section 309-00. Remove the old catalytic converter and install the revised converter 2L2Z-5E212-DA.
Verify that WDS is at the latest level, B21.0 or higher.
Reprogram the PCM with the latest calibration only.
See Contributing Factors Heading for additional information.
NOTE: DO NOT REPLACE CONVERTER MORE THAN ONCE.



2002 2 DOOR EXPLORER SPORT/SPORT TRAC 4.0L

Vehicles Built After 3/27/02

At latest level for engine calibration and converter, no service action will improve the situation.

See Contributing Factors Heading for additional information.
3/4/02 Through 3/27/02

Refer to 2002 Explorer Sport/Sport Trac Workshop Manual, Section 309-00. Remove the old catalytic converter and install the revised converter 2L2Z-5E212-AB only.
See Contributing Factors Heading for additional information.
NOTE: DO NOT REPLACE CONVERTER MORE THAN ONCE OR RECALIBRATE.



2002 2 DOOR EXPLORER SPORT/SPORT TRAC 4.0L M5R4 MANUAL TRANSMISSION

11/2/01 Through 3/4/02 With Manual Transmission

Refer to 2002 Explorer Sport/Sport Trac Workshop Manual, Section 309-00. Remove the old catalytic converter and install the revised converter 2L2Z-5E212-DA only.
See Contributing Factors Heading for additional information.
NOTE: DO NOT REPLACE CONVERTER MORE THAN ONCE OR RECALIBRATE.



2002 SPORT TRAC 4.0L 5R55E TRANSMISSION

11/2/01 Through 3/4/02 With 5R55E Transmission

Refer to 2002 Explorer Sport/Sport Trac Workshop Manual, Section 309-00. Remove the old catalytic converter and install the revised converter 2L2Z-5E212-DA.
Verify that WDS is at the latest level, B21.0 or higher.
Reprogram the PCM with the latest calibration.
See Contributing Factors Heading for additional information.
NOTE: DO NOT REPLACE CONVERTER MORE THAN ONCE.



DRIVE SEQUENCE AFTER REPAIRS COMPLETED

Check engine oil and coolant levels. Verify both are at specified levels before driving vehicle. Perform highway driving at normal highway speeds for 30 miles. The optimum engine speed for this drive sequence is 3,000 to 4,500 rpm, and this can be accomplished by manually selecting the transmission gear state. The goal of the drive procedure is to maintain a constant high temperature level in the exhaust system through the use of increased engine speed. The combination of increased temperature and driving will provide a sulfur cleaning environment for the catalyst system.

CONTRIBUTING FACTORS TO SULFUR SMELL

Factors outside of engineering control may lead to a sulfur odor. A large contributing factor is the amount of sulfur in the fuel. Replacing a Catalytic Converter multiple times will not alleviate the sulfur odor. Several catalyst replacements on the same vehicle may actually increase customer sensitivity to an exhaust odor concern. Based on some driving habits the converter does not get hot enough to burn out stored sulfur residue and can produce a sulfur odor. For example:

Extended Idle - Increase sulfur odor
Stop and go driving - Increase sulfur odor
Trailer Towing - Decrease sulfur odor
Heavy Loads - Decrease sulfur odor
Short trips - Increase sulfur odor
Abrupt accel/decel - Decrease sulfur odor
Hotter driving conditions - Decrease sulfur odor
Hilly terrain - Decrease sulfur odor
Canceling Overdrive - Decrease sulfur odor
Catalysts with 5,000-10,000 Miles (8,000-16,000 Kilometers) are likely to have a sulfur smell due to the highly active state of the new catalyst. Refer to symptom chart #22 of PCED for appropriate year. Additives in fuels (Ethanol, Methanol, ETC.) can cause sulfur odor, suggest using a different fuel source. Geographic variations on sulfur odor intensity are possible due to different refineries supplying fuel to different areas of the country. California regulated fuel will exhibit less sulfur odor.

Experiment with different fuel brands. Some contain more sulfur than others, which can lead to an increase in sulfur odor from the converter. Sulfur odors are an aromatic phenomenon and do not cause any durability or safety concerns with vehicle operation.

To summarize for the customer, explain that sulfur is in the fuel used and the catalyst system on their vehicle as a result of the fuel and driving environment which creates a condition where sulfur has been stored in their exhaust system. The service action performed allows the sulfur to pass through the exhaust system and to clean the existing sulfur deposits. During the initial cleansing of the catalyst it is expected that a sulfur odor may still be present, and this odor may change from the 'rotten egg smell' to that of a 'burning match'. The odor will cease with time.
