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.

PTS HYDROSYSTEM,BILLET TORQUE CONVERTER.

IF THERE IS LOTS OF DEBRIS IN PAN YOU
WILL NEED PTS KIT

P1746*
P0960

EPC, wiring, PCM

EPC solenoid open circuit Voltage through EPC solenoid is checked.
An error will be noted if tolerance is exceeded.
Open circuit causes maximum EPC pressure,
harsh engagements and shifts.
WIRING OR SUPER SOLENOID

P1747*
P0962

EPC, wiring, PCM

EPC solenoid circuit failure, shorted
circuit or output driver
Voltage through EPC solenoid is checked.
An error will be noted if tolerance is exceeded.
Short circuit causes minimum EPC pressure
(minimum capacity) and limits engine torque (alternate firm).
WIRING OR SUPER SOLENOID

P1760

EPC, wiring, PCM

EPC solenoid circuit failure, shorted
circuit or output driver
PCM detected a loss of EPC during
operation.
Unexpected reduction in engine torque. WIRING OR SUPER SOLENOID

P17811

4×4 Low switch

4×4 Low switch closed 4×4 Low switch closed or 4×4 Low
indicator lamp circuit open.
Failed on “” early shift schedules in
4×2 and 4×4 HI range. Failed off “” shifts delayed in 4×4 Low.1
WIRING OR 4X4 SWITCH

P0748**

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.
WIRING OR SUPER SOLENOID

P1729

4×4 Low

4×4 Low switch failure 4×4 Low switch failure during normal
vehicle operation.
Early shifts, harsh shifts, increase in
electronic pressure control valve.
WIRING OR 4X4 SWITCH

P1728

Trans

Transmission slip error The PCM has detected an excessive amount
of slippage during normal operation.
Transmission slippage erratic or no
torque converter clutch operation.
COMPLETE TRANSMISSION FAILURE
