P0110 Air temperature sensor
•
open circuit, short circuit to positive / short circuit to negative
Error cause
•
If open circuit, short circuit to positive: an excessive voltage was detected at PIN 37 of the
ENGINE connector. If short circuit to negative: zero voltage detected. The instrument panel
indicates this error by lighting up in a fixed manner the MI warning light.
Troubleshooting
•
If open circuit, short circuit to positive: check the sensor connector and the Marelli control
unit connector. If they are OK, check sensor continuity: replace the sensor if not OK; if OK,
check continuity between the ENGINE connector PIN 37 and the sensor PIN 1: If continuity
is absent, restore the wiring harness; if ok reconnect the control unit connector and with key
ON check the continuity between PIN 2 of the sensor connector and vehicle ground: if OK,
it means that the error is caused by the cable being shorted to positive and it is necessary
to restore the cable harness between ENGINE PIN 37 and sensor PIN 1; check the sensor
connector and the Marelli control unit connector. If not OK, restore the cable harness. If OK,
check for continuity between the ENGINE connector PIN 6 or 17 and the sensor connector
PIN 2: restore the cable harness if there is no continuity. If there is, it means that the control
unit does not supply the ground connection and therefore should be replaced
•
If short circuit to negative, check the correct resistance of the sensor: if the resistance is null,
replace the sensor; if the resistance is correct, it means that the Green/Pink cable is groun-
ded: restore the cable harness
Lambda sensor
(FRONT CYLINDER)
Function
In charge of telling the control unit whether the mixture is lean or rich
Operation / Operating principle
The Marelli injection control unit reads and interprets a voltage generated by the difference in oxygen
content between the exhaust fumes and the ambient. It does not require an external supply source but,
in order to work properly, it should reach a high operating temperature: that is why there is a heating
circuit inside
Level in electrical circuit diagram:
Lambda probe
Position:
•
on manifold: left side of the vehicle
•
connector: on the ABS support modulator (4 way black connector)
