SUBJECT:
SULFUR ODOR FROM EXHAUST

Exhaust sulfur odor does not necessarily indicate a vehicle concern, but is more likely to be directly related to the fuel. If the vehicle has an excessive
sulfur odor, check for any DTCs set in the PCM. If any DTC is set, diagnose as described in the service manual.
If no vehicle problem is found, recommend the owner try a different brand of fuel. DO NOT REPLACE ANY EMISSIONS COMPONENTS FOR
SULFUR ODOR. PARTS REPLACEMENT WILL HAVE NO EFFECT ON THE ODOR.
WARRANTY INFORMATION
This complaint is NOT considered a warrantable condition. Repairs or replacements of catalytic converters, oxygen sensors, or any other emissions
