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
P0150 Front bank lambda probe
Electrical diagnosis:
•
Short circuit to positive
Error cause:
•
Excessive voltage detected (battery voltage) at PIN 9 and 38 of the ENGINE connector.
Caution: the "lambda probe" parameter is not the actual read value but a recovery value is
displayed.
The instrument panel indicates this error by lighting up in a fixed manner the MI warning light.
Troubleshooting:
•
Short-circuit to positive: with key set to ON, disconnect the sensor connector and measure
PIN 1 voltage on the cable harness side (yellow/orange cable): if the voltage (5 or 12 V) is
present, restore the wiring harness, if the voltage is absent replace the lambda probe
P0155 Front bank lambda probe heating
Electrical diagnosis:
•
short circuit to positive/ open circuit, short circuit to negative
Error cause:
