5. Operate the throttle lever 1, and then
check the TPS 2 output voltage and throt-
tle valve opening angle at the fully open
position É.
NOTE:
The actual TPS output voltage and throttle
valve opening angle may vary according to
environmental conditions and engine tempera-
ture.
6. Operate the throttle lever 1 so that the
TPS 2 output voltage is at 4.5 V or less,
and then check the voltage difference
between TPS 1 and TPS 2.
Example:
If the TPS 1 output voltage is 2.5 V and the
TPS 2 output voltage is 4.5 V, then 4.5–
2.5 = 2.0 V.
2. Measure:
• TPS input voltage
Out of specification → Check the TPS
circuit.
Measurement steps:
1. Disconnect the throttle body assembly
coupler 1.
2. Push the unlock button, and then measure
the input voltage at the throttle body
assembly coupler terminals (wiring har-
ness end).
TPS 2 output voltage with throttle
lever fully open:
4.6–4.7 V
Throttle valve opening angle with
throttle lever fully open:
more than 70°
TPS output voltage difference:
1.9–2.1 V
TPS input voltage (reference data):
Orange (O) – Black/orange (B/O)
4.75–5.25 V
