Main Throttle Sensor (Service Code 11)
If the output voltage is normal, check the wiring for conti-
Disconnect the ECU and sensor connectors.
Wiring Continuity Inspection
ECU Connector [A] ←→
Main Throttle Sensor Connector [B]
Y/R lead (ECU terminal 6) [C]
BR/BK lead (ECU terminal 22) [D]
If the wiring is good, 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 Removal/Installation).
Main Throttle Sensor Resistance Inspection
Turn the ignition switch to OFF.
Disconnect the main throttle sensor connector.
Connect a digital meter [A] to the main throttle sensor
Measure the main throttle sensor resistance.
Main Throttle Sensor Resistance
BL lead [C] ←→ BR/BK lead [D]
4 ∼ 6 kΩ
If the reading is out of the range, replace the throttle body
If the reading is within the range, but the problem still
exists, replace the ECU (see ECU Removal/Installation).
