Quick Guide for VDO Water/Oil Temperature Sensor
The Compatible VDO Temperature Sensor
Only the 50°C to 150°C temperature sensors made by VDO can be read by Aube's automotive gauges (SYL‐1813
and SYL‐1813‐MR). This category of VDO sensors are thermistors with negative temperature coefficient (NTC).
Their resistance values decrease from 323 ohm to 18 ohm as the temperature increases from 50°C to 150°C.
Auber's gauge will measure the resistance value of the VDO sensor and convert it to the corresponding
temperature value.
Wiring
1. Connect the VDO temperature sensor to Auber's automotive gauge as shown in Figure 1. For a VDO
sensor that has only one pole on the top, the sensors' shell serves as the common ground as well as the
other pole for measuring the sensor's resistance. Connect the top pole and the shell of the VDO sensor
to the gauge's terminal 7 and 8. There is no polarity in wiring to these two terminals.
Note: Some VDO temperature sensors have two poles. Please consult the sensor's manual for details.
2. Add a short piece of jumper wire between terminal 6 and 7 on the gauge.
3. Connect the gauge to a 12VDC power source. The gauge's terminal 1 should be connected to the
positive of the 12VDC power.

Settings on the Gauge
1. Change the sensor input type.
In the 0089 menu, change the sensor input type INTY (INTY) to VDO (VDO).
