Change Condition to Cause Response by Input
The purpose is to verify the sensor receives and responds to changes.
- Access, monitor, and record the appropriate sensor PID(s).
- Create the condition or cause the condition to change.
- 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.
