DTC B1468/68 Rear Passenger Side Room Temperature Sensor Circuit

Use the Data List to check if the rear room temperature sensor RH*1 or LH*2 is functioning properly.

• HINT:

• *1: for LHD

• *2: for RHD

• OK:
• The display is as specified in the normal condition.

for LHD

Remove the rear room temperature sensor RH ().

for RHD

Remove the rear room temperature sensor LH ().

Measure the resistance according to the value(s) in the table below.

• Standard Resistance:

• Tester Connection	Condition	Specified Condition
  1 (+) - 2 (-)	10°C (50°F)	3.00 to 3.73 kΩ
  	15°C (59°F)	2.45 to 2.88 kΩ
  	20°C (68°F)	1.95 to 2.30 kΩ
  	25°C (77°F)	1.60 to 1.80 kΩ
  	30°C (86°F)	1.28 to 1.47 kΩ
  	35°C (95°F)	1.00 to 1.22 kΩ
  	40°C (104°F)	0.80 to 1.00 kΩ
  	45°C (113°F)	0.65 to 0.85 kΩ
  	50°C (122°F)	0.50 to 0.70 kΩ
  	55°C (131°F)	0.44 to 0.60 kΩ
  	60°C (140°F)	0.36 to 0.50 kΩ

• NOTICE:

• Even slightly touching the sensor may change the resistance value. Be sure to hold the connector of the sensor.

• HINT:

• As the temperature increases, the resistance decreases (see the graph).
