•
If shorted to positive: excessive voltage has been detected at PIN 1 of the BLUE connector.
•
If the circuit is open, shorted to negative: voltage equal to zero has been detected at PIN 1
of the BLUE connector.
Troubleshooting
•
shorted to positive: disconnect the probe connector and check the sensor correct resistance:
replace the sensor if not OK; if it is OK, restore the cable harness.
•
circuit is open, shorted to negative: check the continuity from probe connector (PIN 3 and
4) towards the probe: if not OK, replace the probe; if it is correct, check the sensor connector
and the Marelli control unit connector. If not OK, restore. If OK, and with key set to ON and
sensor connector disconnected, check if there is battery voltage at PIN 4: se non ok verificare
cavo rosso/nero (lato cablaggio) tra connettore sonda e relè iniezione secondario (n°37 dello
schema elettrico, posizione lato sinistro anteriore del motociclo, primo relè a sinistra vicino
alla bobina, VERIFICARE comunque l'identificazione del relè con il colore dei cavi), se pre-
senti anche errori bobine e iniettori verificare il relè stesso e la sua linea di eccitazione e
potenza; se tensione al PIN 4 presente verificare isolamento da massa del cavo rosa/mar-
rone, lato cablaggio (PIN 3): se non ok ripristinare cablaggio, se ok verificare continuità del
cavo rosa/marrone, lato cablaggio (tra PIN 3 del connettore sensore e PIN 1 connettore
BLU) e ripristinare il cablaggio.
LOGIC ERRORS
Lambda sensor P0140 -
voltage without variation.
Error cause
•
An abnormal behaviour of the voltage at PIN 31 of the BLUE connector has been detected:
the voltage, that should vary over time, keeps a constant value instead.
Troubleshooting
•
check circuit continuity of the lambda sensor connector (PIN 1 PIN2) toward the probe:
replace the lambda sensor if there is no continuity; if there is continuity, check the sensor
connector and the Marelli control unit connector: If not OK, restore. If OK, check continuity
between the BLUE connector PIN 31 and PIN 21 and restore the cable harness.
