Inlet Air Temperature Removal/Installation

CAUTION

Never drop the sensor, especially on a hard surface.

Such a shock to the sensor can damage it.

•Remove the air filter (see Air Filter Removal).

•Disconnect the connector [A] from the inlet air tempera- ture sensor.

•Remove the inlet air temperature sensor [B] and washer.

•Install the inlet air temperature sensor and washer [A].

•Tighten:

Output Voltage Inspection

NOTE

○Be sure the battery is fully charged.

•Remove the ECU (see ECU Removal). Do not disconnect the ECU connector.

•Connect a digital voltmeter to the ECU connector, using needle adapter set.
