Toyota Sienna Service Manual: Inspection
1. INSPECT CRANKSHAFT POSITION SENSOR
- Using an ohmmeter, measure the resistance between the terminals.
Standard resistance
NOTICE:
- "Cold" and "Hot" mean the temperature of the coils themselves.
- "Cold" is from -10C (14F) to 50C (122F) and "Hot" is from 50C (122F) to 100C (212F).
If the resistance is not as specified, replace the crankshaft position sensor.
Removal
1. REMOVE COMPRESSOR AND MAGNETIC CLUTCH
2. REMOVE CRANKSHAFT POSITION SENSOR
Disconnect the crankshaft position sensor
connector.
Remove the bolt, and then remove the cranksh ...
Installation
1. INSTALL CRANKSHAFT POSITION SENSOR

DTC P011B Engine Coolant Temperature / Intake Air Temperature
Correlation
DESCRIPTION
The ECM calculates the difference between the readings of the coolant
temperature sensor and intake air
temperature sensor. If the difference is greater than 20C (68F), the ECM will
judge this as a malfunct ...
Compressor Solenoid Circuit
DESCRIPTION
In this circuit, the compressor receives a refrigerant compression demand
signal from the A/C amplifier.
Based on this signal, the compressor changes the amount of compressor output.
