wsm L3301 - Exhaust Temperature Sensor

ELECTRICAL SYSTEM
L3301, L3901, L4701, WSM
9-S50
(10) Exhaust Temperature Sensor
NOTE
• Since it is not possible to do unit checking for this sensor, judge the sensor is damaged if the relating
electric circuit is normal.

Connector Voltage
1. Disconnect the connector, and turn the main key switch "ON"
position.
2. Measure the voltage with a voltmeter across the terminals
shown in the table below.
3. If the reference value is not indicated as shown in the table
below, check the relating electric circuit.

Sensor Resistance (for Reference)
1. Measure the resistance with an ohmmeter across the terminals
shown in the table below.
2. If the reference value is not indicated, the exhaust temperature
sensor is damaged.
