3-38 FUEL SYSTEM (DFI)
Throttle Sensor (Service Code 11)
If the reading is within the standard, remove the ECU and
check the wiring for continuity between main harness and
sub harness connectors.
Disconnect the ECU and sensor connectors.
ECU Connector [A] ←→
Throttle Sensor Connector [B]
Y lead (ECU terminal 5) [C]
GY lead (ECU terminal 24) [D] ←→
BK lead [E]
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).
Throttle Sensor Resistance Inspection
Disconnect the throttle sensor connector.
Connect a measuring adapter [A] to the throttle sensor.
Special Tool - Measuring Adapter: 57001-1700
Throttle Sensor Resistance
Connections to Adapter:
Digital Meter (+) → R (sensor BL) lead
Digital Meter (–) → BK (sensor BK) lead
4 ∼ 6 kΩ
If the reading is out of the standard, replace the throttle
If the reading is within the standard, but the problem still
exists, replace the ECU (see ECU Removal/Installation).
