and the signal must be greater than 96% for longer than 50 ms.
^
TP sensor signal is less than the minimum threshold - the engine speed must be greater than 400 rev/min for longer than 2 seconds and the
signal must be less than 4% for longer than 50 ms.

Ratio of throttle position to mass of air flow - the calculated throttle angle must be outside limits when the engine speed is between 800
rev/min and 4000 rev/min, the engine load is between 2 and 6.5 and the coolant temperature is above -10 degrees C (14 degrees F).
Should a malfunction of the TP sensor occur the following fault codes may be evident and can be retrieved by Test Book.
