read by the control unit, but a recovery value is
displayed
Lambda correction
•
Example value with key ON: 0 %
•
Example value with engine on: -10% /
+10%
In closed loop, the value must be close to 1.00
(values not within the -15% / +15% interval indi-
cate a fault). In an open circuit, the lambda probe
signal is too low. Therefore, the control unit takes
it as a lean mixture condition and will try to enrich
it. The value read will be +25%: once this value is
reached and kept unchanged for a certain time, the
function diagnosis of the lambda probe is activated
with following deactivation of it.
This diagnosis is activated when the correction
constantly arrives -25%.
CAUTION
BEFORE CARRYING OUT ANY TROUBLESHOOTING,
CAREFULLY READ THE GENERAL TROUBLESHOOTING
CONCEPTS FOR ELECTRICAL DEVICES AT THE BEGIN-
NING OF THE CHECK AND CONTROL SECTION IN THE
ELECTRICAL SYSTEM CHAPTER.
DIAGNOSTIC TOOL: STATUSES
Lambda probe: Start-up_Lean_Rich_Fault due to rich titre_Fault due to lean air-fuel mixture
•
If the probe connector is disconnected (voltage almost equal to zero) it switches to the state
of Fault due to lean air-fuel mixture
Lambda check: Open loop/Closed loop/Rich in closed loop/Lean in closed loop/enriched
•
Closed loop indicates that the control unit is using the lambda probe signal to keep the
combustion is close as possible to the stoichiometric value.
DIAGNOSTIC TOOL: ACTIVATIONS
Lambda probe heater
•
The injection relay (No. 33 in the electrical circuit diagram, placed under the saddle next to
the battery positive, CHECK, however, the identification of the relay with the colour of the
cables) is energised and the heating circuit is closed to ground 5 times (pin 3 of the Lambda
probe connector). Electrical continuity is required in the wiring for the relay to activate cor-
rectly: no errors are generated in case of no activation.
DIAGNOSTIC TOOL: ELECTRICAL ERRORS
