Unlock clip from sensor. Remove overheating/flame sensor. Cable harness for overhear/flame sensor clip Checking the overheating / flame sensor Observe a maximum temperature of 320° C for checking the sensor Overheating sensor Check the overheating sensor with a digital multimeter. If the resistance value is outside the set point indicated in the values, on pg.22 then the sensor must be replaced Flame Senor Check the flame sensor with ta digital multimeter. If the resistance value is outside the set point indicated by the values table on pg 22, then the sensor must be replaced. Installing the overheating / flame sensor Special tool - only for AIRTRONIC D2 Overheating sensor / flame sensor For AIRTRONIC D2 (Assembly without using purpose made tool) Mount the special tool on the sensor Place the sensor on the heat exchanger using the special tool. The special tool slides on the heat exchanger until the sensor meets the collar (installation site of the sensor) Lock the sensor in place and remove the purpose made tool. It is then vital to check that the sensor sits flat on the heat exchanger. If necessary use a mirror and lamp to aid correct assembly. Route the cable harness sensor along the clip eyelet to the control unit and connect.
