DORSODURO 1200 ABS - ATC
Location:
•
on the vehicle: exhaust end behind the
rear head
•
connector: on the right side, at the back
of the filter box
Electrical specifications
•
Heater circuit: 7-9Ω at Ambient temp.
Pin out:
1. Sensor signal + (black wire)
2. Sensor signal - (grey wire)
3. Heater ground connection (white cable)
4. Heater power supply (white cable)
DIAGNOSIS INSTRUMENT: PARAMETERS
Lambda probe
•
Example value with key ON: 0 mV
•
Example value with engine on:
100--900 mV
If there is a short circuit at + 5 V or above, the
lambda probe parameter is not equal to the value
read by the control unit; a recovery value is dis-
played instead
Lambda correction
•
Example value with key ON: 1.00 mV
•
Example value with engine on: 0.90 -
1.10mV
In closed loop, the value must be close to 1.00
(values not within the 0.90 - 1.10 interval indicate
a fault): for example, value 0.75 corresponds to
+25% with respect to the reference injection time;
1.25 corresponds to -25%. In an open circuit, the
lambda probe signal is too low. Therefore, the con-
trol unit takes it as a lean combustion condition and
will try to enrich it. The value read will be 0.75: once
this correction has been tried, the value shifts to
1.00 fixed and the Lambda probe error is signalled
CAUTION
BEFORE CARRYING OUT ANY TROUBLESHOOTING,
