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.

Intake Air Temperature Sensor Gradient Too High
DESCRIPTION
The Intake Air Temperature (IAT) sensor, mounted on the Mass Air Flow (MAF)
meter, monitors the IAT.
The IAT sensor has a built-in thermistor with a resistance that varies according
to the temperature of the
intake air. When the IAT becomes low, the resistance of the the ...
