For the check, proceed as follows.
Connect the diagnostic tester to the vehicle. Select the «parameters» function. The following values
are reported:
THROTTLE OPEN. %
The displayed value refers to the valve opening percentage. Check that a progressive actuation of the
valve corresponds to an equal increase of the opening percentage value. A 0% percentage denotes
the minimum position (approx. 20% opening)
TPS1 OUTPUT = V
TPS2 OUTPUT = V
The displayed tensions refers to the TPS1 and TPS2 signals. Progressively open the valve and check
the following conditions:
TPS1 - Increases progressively
TPS2 - Decreases progressively
Set the valve opening to 50% and check that at this value the signals TPS1 and TPS2 are equal or very
close (a few hundreds volts difference).
N.B.
FOR A MORE PRECISE CHECK, PROGRESSIVELY OPEN THE VALVE DIRECTLY BY THE
THROTTLE BODY. USING A FLEXIBLE TRANSMISSION CAUSES AN IRREGULAR OPENING
TPS1 ZERO = V
TPS2 ZERO = V
TPS TO REST = (NO - YES)
The TPS signal reset function is used when signals TPS are efficient.
Select the errors function.
Check the following errors and relevant ISO codes:

Both TPS signals missing. Acknowl-
edgement occurs when voltages are
close to:
0V = short circuit
5V = open circuit
In the event of intermittent fault, the sys-
tem switches to the "occurred" status.
To reset the function, switch ON - OFF
- ON to allow switching to the stored sta-
tus.
