F-Series and E-Series Diagnostic Trouble Codes And Repair Procedures
Special thanks to Pat Barrett and the folks at Level Ten Products for this article. Many of the parts needed to repair the issues can be purchased from Level Ten Products and we recommend you visit their web site or give them a call at (973) 827-1000.
The E40D and 4R100 codes are for gas and diesel for 1996 – 2003 E and F-series Super Duty (250 350 450 550). In 2004 they changed to a 5R110 transmission and the codes are different. The codes for 4R70W and 4R75w are for F-150 and E-150 1996- 2006.

EPC solenoid |
EPC solenoid circuit failure |
Voltage through EPC solenoid is checked. An error will be noted if tolerance is exceeded. |
Short circuit results in minimum EPC pressure (minimum capacity) and limits engine torque (alternate firm). Not all gears present. Open circuit: maximum PC A pressure, harsh engagements and shifts. |
