SPIDER MAX 500
The intake air temperature sensor is fitted inside the lower part of the throttle body on the airbox side.
The sensor is NTC with the same operating diagram of the coolant temperature sensor.
This signal is used in order to optimise the engine operation but it remains a less important information compared to the
coolant temperature signal.
In case of failure of the circuit, the central unit switches the injection led on and enable the protections control thus
ensuring the engine operation.
In order to check the sensor and the circuit, proceed as follows:
Connect the diagnostic multimeter. Select the menu from the "ERRORS" function. Check the intake air temperature
sensor for anomalies.
The EMS system did not receive any temperature values not included within the possible
value range. In case of a reliable suspect that the temperature read is not correct, proceed
with the check indicated below.
Before performing the sensor and circuit check, we suggest to wait for the engine to cool down completely until
the motorcycle temperature reaches the room temperature.
Move the key switch to the "ON" position and the emergency switch to "RUN" and lift the side stand.
Select the menu from "PARAMETERS" on the diagnostic multimeter.
Check the following indications: coolant temperature - intake air temperature - room temperature indicated by
the digital instrument.
The three values should be equal or slightly differ (e.g.: 1° C).
The intake air temperature sensor may be reading a correct value.
Fit the diagnostic wiring. Do not connect the central unit connector.
