NOTE
Be sure the battery is fully charged.
Harness [B] Water Temperature Sensor [C]
Special Tool - Measuring Adapter: 57001-1700
Water Temperature Sensor Output Voltage Connections to Adapter: Digital Meter (+) → R (sensor O) lead Digital Meter (–) → BK (sensor BR/BK) lead
ECU Intake Temperature Sensor Throttle Body Assy Connectors
Output Voltage
Standard: About DC 2.80 2.97 V at
20°C (68°F)
NOTE
The output voltage changes according to the coolant temperature in the engine.
If the reading is within the standard, check the ECU for its ground, and power supply (see ECU Power Supply Inspection in the Fuel System (DFI) chapter).
If the ground and power supply are good, replace the ECU (see ECU Removal/Installation in the Fuel System (DFI) chapter).
If the reading is out of the standard, remove the ECU and check the wiring for continuity between harness connectors.
Special Tool - Hand Tester: 57001-1394
Disconnect the ECU and sensor connectors.
Wiring Continuity Inspection ECU Connector [A] ←→ Water Temperature Sensor Connector [B] O lead (ECU terminal 23) [C] BR/BK lead (ECU terminal 13) [D]
If the wiring is good, check the water temperature sensor resistance (see Water Temperature Sensor Resistance Inspection).
