SENSOR DOCUMENTATION
Notes: Cylinder head thermocouple technical documentation, dimensions and pinout – Version 1.01
Introduction
Aim instruments can measure and record cylinder head temperature using a sensor (thermocouple)
positioned under the spark plug. The thermocouple presents a turn in the lower part to make
installation and disinstallation easier.
All Aim thermocouples are K-type sensors.
Installation notes
The head temperature sensor sits between the spark plug and the cylinder head. To keep the sensor
in contact with the cylinder head, it is necessary to remove the washer from the plug when
installing the thermocouple.
While running the thermocouple cable along the chassis, be careful to keep it as far as possible
from other cables (such as RPM or lap receiver cables) in order to minimize interferences between
the cables.
ATTENTION: Before screwing back the spark plug inside the cylinder head, ensure that the
sensor is firmly mated with the cylinder head and, when tightening and loosening the spark plug,
minimize movement of the sensor. Failure to observe this precaution may result in damage to the
sensor
For a correct installation, please watch Figure 2:
