WEAK POINTS, SYSTEM BY SYSTEM
What fails on the 2020+ 6.7 Power Stroke, and how we fix it.
Tap a system to see what fails, what you’ll notice and how we fix it. Common = we see it often. Towing / tuned = shows up with heavy loads or added power. High miles = age and wear items.
Fuel system
CP4.2 pump wearCommon
You’ll notice: sudden stall or no-start, low rail pressure codes, metal in the filter.
Why: The CP4 can wear and send metal through the fuel system. Ford issued a recall on some 2020–2022 trucks.
Our fix: We check recall status, test the fuel system and repair it.
Water in the fuelCommon
You’ll notice: a water-in-fuel light, rough running.
Why: Water and bad fuel are hard on the CP4 and injectors.
Our fix: We drain and clean the system and change both filters on time.
DEF, DPF & EGR
DEF and NOx sensorsCommon
You’ll notice: a “Service DEF” message, a countdown to reduced speed, derate.
Why: DEF, NOx and other exhaust sensors fail with heat and age.
Our fix: We diagnose the system and replace the failed part, keeping it legal.
DPF and EGR sootHigh miles
You’ll notice: frequent regens, low power, EGR codes.
Why: Short trips and idling load the DPF and EGR with soot.
Our fix: We clean or replace emissions parts the legal way.
Soot on the MAP sensorCommon
You’ll notice: low power, boost codes.
Why: Soot builds up on the intake pressure sensor.
Our fix: We clean or replace it; a Banks MAP sensor kit helps it last.
10R140 ten-speed
Harsh or odd shiftsCommon
You’ll notice: clunky shifts, hunting for gears.
Why: Early trucks needed software updates, and old fluid and heat cause wear.
Our fix: We check for updates, service the fluid and diagnose the codes.
Front end & steering
Loose steering and death wobbleHigh miles
You’ll notice: wandering, play in the wheel, a shake after a bump.
Why: The heavy solid front axle wears out its tie rods, ball joints and track bar.
Our fix: We rebuild the front end with heavy-duty parts and set the alignment.

MAINTENANCE SCHEDULE
2020+ 6.7 Power Stroke service intervals.
These are Ford’s factory intervals from the owner’s manual schedule. The factory “severe” column covers towing, dusty roads, short trips and long idling, which describes most working trucks in Southern Arizona. Our recommendation follows the severe schedule, with oil every 5,000 miles and fuel filters every 10,000.
| Service | Factory, normal use | Factory, severe use | Our recommendation |
|---|---|---|---|
| Engine oil & filter | 10,000 mi or oil life monitor | 5,000 mi or oil life monitor | Every 5,000 mi |
| Fuel filters (both) | 22,500 mi or dash message | 15,000 mi / 6 months / 600 hours | Every 10,000 mi |
| Engine air filter & pre-filter | 45,000 mi | Inspect at every oil change | Inspect at every oil change |
| Coolant (both loops) | 105,000 mi / 6 years first, then 45,000 mi / 36 months | 60,000 mi first, then 45,000 mi / 36 months | 60,000 mi first, then 45,000 mi / 36 months |
| Crankcase vent (CCV) separator | About 100,000 mi on some trucks | — | About 100,000 mi on some trucks |
| 10R140 fluid & filter | 150,000 mi | 50,000 mi | 50,000 mi |
| Transfer case fluid | 150,000 mi | 60,000 mi | 60,000 mi |
| Front axle fluid | 150,000 mi | 50,000 mi | 50,000 mi |
| Rear axle fluid | 100,000 mi | 50,000 mi | 50,000 mi |
Always go by your owner’s manual for your exact truck. Factory figures are maximums, and the dash service reminder comes first when it shows sooner.
