Functional Description:
●
Use ECU provided DC 5V power supply, has the three-pin coupler, one
for the power supply pin; one for a voltage output pin; one for a
grounding pin.
●
Its main component is a sophisticated type of variable resistor.
●
Installed on the throttle body beside the throttle through (the
accelerator) rotates, the output of linear voltage signal provided ECU
perception and judgment then throttle position (opening), and in this
signal with have the most appropriate fuel injection and ignition timing
control.

Testing Procedures:
1. Sensor connected properly (using the probe tool), or can be removed
connector to voltage measurements (direct measurement).
2. Opened the main switch, but do not to start engine.
3. Use "voltage meter" DC stalls (DCV) to check sensor voltage.
4. Confirmed working voltage:
●
Voltage meter negative access to the inlet pressure sensor third pin
(Green / Red).
●
Voltage meter positive access to the inlet pressure sensor first pin
(Yellow / Black).
5. Throttle output signal recognition (using the probe tool)
●
Voltage meter negative access to the sensor third pin (Green / Red).
●
Voltage meter positive access to the sensor first pin (white / Brown).
●
Measurements were full throttle at full throttle closed the values of
the output voltage.
Cautions
●
Attentions to the tools required close to the probe wire waterproof
apron penetrate skin and internal terminal before measurements to
the correct value.
Detection judge:
