Change Condition to Cause Response by Input

WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2005 Ford RV Cutaway, 2005 Ford Pickup, 2005 Ford F550 Super Duty, 2005 Ford F450 Super Duty, and 2005 Ford Excursion. However, it is still accessible from the selected car via links, so may be relevant.

The purpose is to verify the sensor receives and responds to changes.

  1. Access, monitor, and record the appropriate sensor PID(s).
  2. Create the condition or cause the condition to change.
  3. If the value changes appropriately, then it should be operating OK.

    Examples:

    • View the engine oil temperature (EOT) PID while the engine warms.
    • It should change from a higher voltage (2.6 volts) for a cold engine, to a lower voltage as the engine warms (0.6 volts).
    • Apply and release the accelerator pedal while monitoring the accelerator pedal position (APP) PID for a change of state.
    • Apply and release the brake pedal while monitoring the brake pedal position (BPP) PID for a change of state.
