Power Take-Off (PTO)
WARNING: This page is about a different car, the 2004 Ford Pickup, 2004 Ford F550 Super Duty, 2004 Ford F450 Super Duty, 2004 Ford Excursion, and 2004 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Failure to install the wire from the powertrain control module (PCM) pin 322 to pin 294 will result in low line pressure leading to PTO and transmission failure.
Some 6.8L and 6.0L SuperDuty vehicles have power take-off (PTO) capability. During stationary operation in PARK or NEUTRAL, the torque converter is locked up when the PTO is ON and the engine operates at 1200 rpm. The following schedule shows expected rpm and line pressure while driving with the PTO in use.
RPM AND LINE PRESSURE
| RPM | Line Pressure |
|---|---|
| 625 | 80 psi |
| 800 | 100 psi |
| 1000 | 150 psi |
| 1200 | 150 psi |
| 2500 | 150 psi |
