Kawasaki Ninja Service Manual: Intake Air Pressure Sensor #2 Output Voltage Inspection

Kawasaki Ninja Service Manual / Self-Diagnosis System / Intake Air Pressure Sensor #2 (Service Code 16) / Intake Air Pressure Sensor #2 Output Voltage Inspection

Measure the output voltage at the intake air pressure sensor #2 in the same way as input voltage inspection, note the following.

Disconnect the intake air pressure sensor #2 connector and connect the measuring adapter [A] between these connectors.

Intake Air Pressure Sensor #2 Output Voltage Inspection

Special Tool - Measuring Adapter: 57001-1700

Intake Air Pressure Sensor #2 Output Voltage Connections to Adapter: Digital Meter (+) → Y (sensor G/W) lead Digital Meter (–) → BK (sensor BR/BK) lead

Intake Air Pressure Sensor #2 Output Voltage Inspection

Measure the output voltage with the engine stopped and with the connector joined.
Turn the ignition switch to ON.

Output Voltage Usable Range: DC 3.80 4.20 V at
standard atmospheric pressure (101.32 kPa, 76 cmHg absolute)

NOTE

The output voltage changes according to the local atmospheric pressure.

Turn the ignition switch to OFF.

If the reading is out of the usable range, replace the sensor.

If the reading is within the usable range, remove the ECU and check the wiring for continuity between main harness connector.

Special Tool - Hand Tester: 57001-1394

Disconnect the ECU and sensor connectors.
