Sensors

Logic of naming sensors in VW-group is simple it contains "G" (german "Geber") + sensor number. The sensor number is unique. Here you can find fitting location, connectors and pins description, some information about sensors signals.

To our mind, sensors information is reference, so there is only simple search by sensor number.

Left vent temperature sender -G150

2 - Left vent temperature sender -G150

3 - Central vent control motor -V102

 

The climate control is fully automatic, with separate temperature control for the left and right sides of the passenger compartment. The left vent temperature sender -G150 is always fitted in the air duct to the left dash panel vent. The air flowing out of the heater/air conditioner unit into the passenger compartment is recorded with a temperature-dependent resistance and so is available as an influencing variable in the temperature monitoring and control function of the Climatronic control unit -J255. The left vent temperature sender -G150 is designed as an NTC sensor. As the temperature falls the electrical resistance increases. The resistance is evaluated as a signal by the Climatronic control unit -J255, and is used to regulate the air distribution and the blower flow rate.

 

YZ Note:

Experience shows that temperature senders are the most frequent cause of temperature control faults. They do not usually fail immediately, but deliver false values to the control unit based on an additional wire resistance as a result of damage or corrosion in the connector contacts. Thus a comparison of the values of more senders (-G150 and -G151, -G263) in the relevant display zones is recommended for optimum diagnosis.
