System Description
Fan speed is automatically controlled by the temperature setting, ambient temperature, in-vehicle temperature, intake temperature, amount of sunload and air mix door position.
By pressing the AUTO switch, the blower motor starts to gradually increase airflow volume.
When engine coolant temperature is low, the blower motor operation is delayed to prevent cool air from flowing.

Starting Fan Speed Control
Start-up from COLD SOAK Condition (Automatic mode) In cold start-up condition where the engine coolant temperature is below 56C (133F), the blower does not operate for a short period of time (up to 150 seconds). The exact start delay time varies depending on the ambient temperature and engine coolant temperature.
In the most extreme case (very low ambient temperature) the blower start delay is 150 seconds, as described above. After this delay, the blower will operate at low speed until the engine coolant temperature rises above 56C (133F), and then the fan speed increases to the objective speed.
Start-up from usual or HOT SOAK Condition (Automatic mode) The blower will begin operation momentarily after the AUTO switch is pressed. The fan speed rises gradually to the objective speed over a time period of 3 seconds or less (actual time depends on the objective fan speed).

Inspection and Judgment
INSPECTION
Inspect the amount of engine oil. Replenish the
engine oil if necessary.
Drive for about 10 minutes to warm up the
vehicle so that the
CVT fluid temperature is 50 to 80C (122 to 176F). Inspect the
amount of CVT fluid. Repleni ...

P0550 PSP sensor
Description
Power steering pressure (PSP) sensor is installed to the power steering
high-pressure tube and detects a
power steering load.
This sensor is a potentiometer which transforms the power steering load into
output voltage, and emits the
voltage signal to the ECM. The ECM controls ...
