is displayed at the same time, this means that the blue/green cable common for both sensors
is shorted to positive.
NOTES No error is detected if the sensor does not work correctly or the control unit connector
or sensor terminals are rusty: then check through Axone if the temperature indicated is plausible
in relation to the ambient temperature. Check also that the sensor electrical characteristics are
observed: replace the sensor if not OK; if it is OK, check the sensor connector and the Walbro
control unit connector
