Toyota Sienna Service Manual: Front Clearance Sonar Sensor RH Circuit
DESCRIPTION
An ultrasonic sensor consists of a sensor portion that transmits and receives ultrasonic waves and a preamplifier that amplifies them. The ultrasonic sensor outputs the ultrasonic waves and sends the reveiced signals to the clearance warning ECU.
WIRING DIAGRAM
INSPECTION PROCEDURE
1 INSPECT NO. 1 ULTRASONIC SENSOR
- Remove the No. 1 ultrasonic sensor.
- Measure the resistance according to the value(s) in the table below.
