Change Input and Verify Output Response
WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2004 Ford RV Cutaway, 2004 Ford Pickup, 2004 Ford F550 Super Duty, 2004 Ford F450 Super Duty, and 2004 Ford Excursion. However, it is still accessible from the selected car via links, so may be relevant.
The purpose is to verify how the PCM and actuator circuit responds to sensor input.
- Select, view the appropriate sensor PID(s).
- Create condition to cause input condition to change.
- Observe change (response) in actuator PID or actuator signal circuit measured by a measuring device.
Example:
- Increase accelerator pedal position under load, observe RPM DSD PID and circuit change.
