Service Procedure
NOTE: Perform the sulfur removal procedure one time only. If the vehicle exhibits this condition again, proceed with the replacement of the catalytic converter(s).
1. Perform Pinpoint Test HF: Catalyst Efficiency Monitor And Exhaust Systems Steps HF1-HF6. Refer to the Workshop Manual (WSM), Section 309-00D Exhaust System – 3.5L V6 PowerBoost, Diagnosis and Testing, Catalyst System.
2. Is the concern still present?
(1). Yes – proceed to Step 3.
(2). No – this article does not apply.
3. Retrieve onboard diagnostics (OBD) mode 6 data from the Ford Diagnosis and Repair System (FDRS) and record oxygen storage values from both banks.
4. Perform the following sulfur removal cycle.
(1). Warm up the engine to its normal operating temperature.
(2). Identify an appropriate route to allow speeds around 70 mph (113 km/h).
(3). From 30 mph (48 km/h) or slower, accelerate at wide open throttle (WOT) until the vehicle reaches 65 mph (105 km/h).
(4). Place the transmission into manual (M).
(5). Select 4th gear.
(6). For at least 45 minutes, perform periodic, repeated medium (25%-50% throttle) acceleration / closed pedal (foot off throttle) deceleration events driving alternately between 60 mph and 70 mph (97 km/h and 113 km/h).
5. Take the transmission out of manual mode (M). Drive the vehicle normally at 55-65 mph (88-105 km/h) for 15 minutes.
6. Clear DTCs P0420 and/or P0430 stored in the PCM. This resets the mode 6 data to zero.
7. Run a catalyst monitor drive cycle. Refer to Pinpoint Test HF: Catalyst Efficiency Monitor And Exhaust Systems Step HF11 > On Board Diagnostics (OBD) Drive Cycle.
8. Retrieve OBD mode 6 data after the catalyst oxygen storage values have been populated. Have the oxygen storage values decreased from what was recorded in Step 3 and are they less than 0.3 on affected bank(s)?
(1). Yes – repair is complete.
(2). No – replace the catalytic converter(s) on the affected bank(s) that has a value greater than 0.3. Refer to the WSM, Section 309-00 > Exhaust System > Removal and Installation > Catalytic Converter.

NOTE: Perform the sulfur removal procedure one time only. If the vehicle exhibits this condition again, proceed with the replacement of the catalytic converter(s).
1. Perform Pinpoint Test HF: Catalyst Efficiency Monitor And Exhaust Systems Steps HF1-HF6. Refer to the Workshop Manual (WSM), Section 309-00D Exhaust System – 3.5L V6 PowerBoost, Diagnosis and Testing, Catalyst System.
2. Is the concern still present? (1). Yes – proceed to Step 3.
(2). No – this article does not apply.
3. Retrieve onboard diagnostics (OBD) mode 6 data from the Ford Diagnosis and Repair System (FDRS) and record oxygen storage values from both banks.
4. Perform the following sulfur removal cycle.
(1). Warm up the engine to its normal operating temperature.
(2). Identify an appropriate route to allow speeds around 70 mph (113 km/h).
(3). From 30 mph (48 km/h) or slower, accelerate at wide open throttle (WOT) until the vehicle reaches 65 mph (105 km/h).
(4). Place the transmission into manual (M). (5). Select 4th gear.
(6). For at least 45 minutes, perform periodic, repeated medium (25%-50% throttle) acceleration / closed pedal (foot off throttle) deceleration events driving alternately between 60 mph and 70 mph (97 km/h and 113 km/h).
5. Take the transmission out of manual mode (M). Drive the vehicle normally at 55-65 mph (88-105 km/h) for 15 minutes.
6. Clear DTCs P0420 and/or P0430 stored in the PCM. This resets the mode 6 data to zero.
7. Run a catalyst monitor drive cycle. Refer to Pinpoint Test HF: Catalyst Efficiency Monitor And Exhaust Systems Step HF11 > On Board Diagnostics (OBD) Drive Cycle.
8. Retrieve OBD mode 6 data after the catalyst oxygen storage values have been populated. Have the oxygen storage values decreased from what was recorded in Step 3 and are they less than 0.3 on affected bank(s)? (1). Yes – repair is complete.
(2). No – replace the catalytic converter(s) on the affected bank(s) that has a value greater than 0.3. Refer to the WSM, Section 309-00 > Exhaust System > Removal and Installation > Catalytic Converter. © 2023 Ford Motor Company All rights reserved.
