Toyota Sienna Service Manual: Inspection
1. INSPECT REAR SPEED SENSOR
(a) Remove the seat cushion and seatback.
(b) Disconnect the speed sensor connector.
(c) Measure the resistance between terminals 1 and 2 of the speed sensor connector
OK: Resistance: 1.1 +- 0.2 kΩ at 25 +- 5 °C
(d) Measure the resistance between each of terminals 1 and 2 of skid control sensor connector and body ground.
OK: Resistance: 1 MΩ or higher
NOTICE: Check the speed sensor signal last (See page BC-10).

Knock Sensor 1 Circuit Low Input
DESCRIPTION
A flat type knock sensor (non-resonant type) has a structure that can detect
vibrations over a wide band of
frequencies: between approximately 6 kHz and 15 kHz.
Knock sensors are fitted onto the engine block to detect engine knocking.
The knock sensor contains a piezoelectr ...
