Kawasaki Ninja Service Manual: Intake Air Temperature Sensor Output Voltage Inspection

Kawasaki Ninja Service Manual / Self-Diagnosis System / Intake Air Temperature Sensor (Service Code 13) / Intake Air Temperature Sensor Output Voltage Inspection

NOTE

Be sure the battery is fully charged.

Special Tool - Measuring Adapter: 57001-1700

Intake Air Temperature Sensor Output Voltage Inspection


Intake Air Temperature Sensor Output Voltage Inspection


Intake Air Temperature Sensor Output Voltage Connections to Adapter: Digital Meter (+) → R (sensor R/BK) lead Digital Meter (–) → BK (sensor BR/BK) lead

Output Voltage Standard: About DC 2.44 ∼ 2.69 V at 25°C (77°F)

NOTE

The output voltage changes according to the intake air temperature.

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 main harness connectors.

Intake Air Temperature Sensor Output Voltage Inspection


Disconnect the ECU and sensor connectors.

Wiring Inspection ECU Connector [A] ←→ Intake Air Temperature Sensor Connector [B] R/BK lead (ECU terminal 37) [C] BR/BK lead (ECU terminal 13) [D]

If the wiring is good, check the intake air temperature sensor resistance (see Intake Air Temperature Sensor Resistance Inspection).
