FUEL SYSTEM (DFI) 3-53
Main Throttle Sensor (Service Code 11)
NOTE
○
The standard voltage refers to the value when the volt-
age reading at the Input Voltage Inspection shows 5V
exactly.
○
When the input voltage reading shows other than 5V,
derive a voltage range as follows.
Example:
In the case of a input voltage of 4.75 V.
0.65 × 4.75 ÷ 5.00 = 0.62 V
3.90 × 4.75 ÷ 5.00 = 3.71 V
Thus, the valid range is 0.62
∼
3.71 V
If the output voltage is within the standard range, check
the ECU for its ground, and power supply (see ECU
Power Supply Inspection). If the ground and power
supply are good, replace the ECU (see ECU section).
If the output voltage is far out of the standard range (e.g.
when the wiring is open, the reading is 0 V), check the
output voltage again at the sensor connector.
