WARNING: This page is about a different car, the 2011 Ford Pickup, 2011 Ford F550 Super Duty, 2011 Ford F450 Super Duty, and 2011 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
PCM INPUTS REFERENCE CHART
| Item | Affect | Description |
|---|---|---|
| Engine speed | Directly affects shift scheduling, Torque Converter Clutch (TCC) control, line pressure and transmission diagnostics. Indirectly affects shift pressure control. | Engine speed signal in rpm units, provided by the crankshaft position sensor |
| Engine torque estimate | Directly affects shift pressure control, TCC control and transmission diagnostics. Indirectly affects shift scheduling and TCC scheduling. | Engine torque estimate is based on engine load and is affected by several engine control sensors |
| Accelerator pedal position | Directly affects shift scheduling, TCC scheduling and transmission diagnostics. Indirectly affects TCC control and shift control. | |
| Commanded engine torque | Directly affects shift scheduling, TCC scheduling and transmission diagnostics. Indirectly affects shift control. | Commanded engine torque is engine torque estimate in comparison to accelerator pedal position (driver input) |
| Brake pedal position | Directly affects shift scheduling and TCC scheduling |
This transmission uses 2 types of solenoids, normally low and normally high. Normally low solenoids provide hydraulic pressure proportional to supplied current. A normally low solenoid will output very low pressure with low (50 mA) or no current, while it will supply high pressure with high current (850 mA). Normally high solenoids provide pressure inversely-proportional to supplied current. Normally high solenoids provide full output of pressure with low or no current (50 mA) and very low pressure with high current (850 mA).
