Ford Trucks Truck EGR Fault Solution
We solve power loss, black smoke and warning-light problems caused by the EGR valve and EGR cooler on Ford Trucks trucks and tractor units with ECU software. The cause of the fault is diagnosed first and the original software is backed up.
On trucks and tractor units EGR faults are common at high mileage. The symptoms are reduced pulling power on hills, black smoke, higher fuel consumption and frequent particulate filter regeneration; a faulty EGR also fills the DPF quickly.
The EGR system returns part of the exhaust gas to the intake. That gas carries soot; over time the valve, the cooler and the intake manifold become coated with it. When the valve sticks the engine cannot draw clean air: power drops, smoke increases, idle becomes unstable and the ECU stores a fault.
When the EGR cooler is perforated, coolant passes to the exhaust side and the engine starts losing coolant; in that case software alone is not the answer and the cooler has to be bypassed or replaced. We tell you which job is right after diagnosis.
When is it needed?
- EGR valve fault and soot build-up
- Rough idle, smoke, power loss
- Carbon build-up in the intake manifold
Typical duration: 1–2 hours
Ford Trucks EGR Fault Solution: supported control units
Control units for which our library holds a verified solution for this service on Ford Trucks: BOSCH EDC17CV41. The same model can carry a different ECU depending on build year and engine option; we confirm compatibility from a photo of the ECU label or from the file read out.
