1 (1598/11) + 16 (1598/12)

Left Vent Temperature Sensor G150

Ignition switched off

Measure temperature at sensor installation

Depending on temperature at sensor installation

Use wiring diagram to locate and eliminate short circuit, open circuit in wiring or contact resistance

Right Vent Temperature Sensor G151

Replace sensor

NOTE:

The wiring to these sensors terminates at different connectors. Use is therefore either to be made of a second Test Box V.A.G 1598A or the measuring instrument must be connected using a suitable test lead from the Connector Test Set V.A.G 1594C directly to the Adapter - 16 Terminals V.A.G 1598/12.
