Air temperature sensor

Function

It tells the control unit the intake air temperature in

order to calculate oxygen presence so as to opti-

mise the petrol quantity necessary for correct com-

bustion.

Operation / Operating principle

NTC type sensor (resistance sensor, inversely

variable with temperature).

Level in wiring diagram:Temperature sensors

Location:

•

sensor: on the right side of the filter

casing, next to the control unit

•

connector: on the sensor

Electrical characteristics:

•

Resistance at 0°: 9.75 kΩ ± 5%

•

Resistance at 10°: 5.970 kΩ ± 5%

•

Resistance at 20°: 3.747 kΩ ± 5%

•

Resistance at 25°: 3.000 kΩ ± 5%

•

Resistance at 30°: 2.417 kΩ ± 5%

Pin-out:

•

Grey (cable harness side): Ground connection

•

Pink/black (cable harness side): 0-5 V signal

AXONE:PARAMETERS

Air temperature

In case of failure, the value set by the control unit is 20 °C (68 °F)

AXONE: ELECTRICAL ERRORS

air temperature sensor open circuit, shorted to positive / shorted to negative.

Error cause

•

If the circuit is open, shorted to positive: excessive voltage has been detected at PIN 18 of

the control unit connector.

•

If shorted to negative: voltage equal to zero has been detected at PIN 18 of the control unit

connector

Troubleshooting

•

If the circuit is open, shorted to positive: check sensor connector and Marelli control unit

connector; if not OK, restore cable harness; if OK, check sensor continuity; if it is not OK,

replace the sensor; if it is OK, check the continuity between PIN 18 of the control unit con-
