| Schematic Diagram |

Inspection 1. After disconnecting the vapor hose from the PCV valve, remove the PCV valve. 2. Reconnect the PCV valve to the vapor hose. 3.
Inspection 1. Ignition "ON" 2. Using the scan tool. 3. Emit intensive light toward photo sensor using a lamp, and check the output voltage change. 4. The voltage will rise with higher intensive light and reduce with lower intensive light.
Description 1. The ambient temperature sensor is located at the front of the condenser and detects ambient air temperature. It is a negative type thermistor resistance will increase with lower temperature, and decrease with higher temperatures.
