(or any value below 10%), if there is any fault in Driver Direction potentiometer. 

YES  

Go to TERMINAL AND CONNECTOR INSPECTION procedure. 

NO  

Fault is intermittent caused by poor contact in the sensor's and/or A/C controller's connector or was 
repaired and A/C controller memory was not cleared. Thoroughly check connectors for looseness, poor 
connection, bending, corrosion, contamination, deterioration, or damage. Repair or replace as necessary 
and then go to "VERIFICATION OF VEHICLE REPAIR" procedure. 

TERMINAL AND CONNECTOR INSPECTION 

Refer to DTC B1206. 

SIGNAL CIRCUIT INSPECTION 

1. Check for short in harness. 

1. Ignition "OFF"  

2. Disconnect Driver mode Actuator.  

3. Measure resistance between terminal "5" and "6" of Driver Direction potentiometer. 

Specification: Approx. infinity ohms

GENERAL DESCRIPTION 

Intake door located at heater unit controls the inlet of car. When driver operates the intake switch, A/C 
controller recirculation receives mode signal from intake switch and operates intake door actuator to turn intake 
door to intended position, (with fresh mode signal, intake door is closed and with fresh mode signal, intake door 
is opened). 

DTC DESCRIPTION 

The A/C controller sets DTC B1208 if there is an open circuit or poor connection in the intake potentiometer.
