I think it's the sensor for an engine temp idiot light.
The sensor that disables the lambda system in late eightees cars when the motor is cold is in the right side chain case cover.
Left side chain case has the thermal time switch for the cold start valve. It's tied in with the starter motor and has it's own thermal heater to disable the cold start valve so it doesn't flood the motor in case the car won't start while somebody keeps on trying over and over again and again.. until the battery is dead or the starter motor says see ya.
