NOTE

Modified temperature sensor for evaporator







A Modified temperature sensor
B Previous temperature sensor


If the modified temperature sensor (figure, version A) with metal tube is not yet installed in model 201, it must be renewed. (Production breakpoint June 1987)







Removing
1 Disconnect 2-pole connector (arrow). Test temperature sensor (B10/6) using ohmmeter. If the temperature sensor is faulty, release the cable straps on the cable harness.
2 Remove cover on air inlet Procedures







3 Pull temperature sensor (B10/6) out of guide tube.


Installing
Install in the reverse sequence.Test temperature sensor (B10/6) with ohmmeter beforehand.
