•
Check the sensor connector PIN 3 ground insulation. In the absence of insulation restore
the cabling.
•
If PIN 3 is insulated from ground and in the absence of other errors (fuel pump, injector, coil),
this means that the control unit is most likely faulty.
LEFT LAMBDA
Level in electrical circuit diagram:
Left lambda
probe
Location:
•
sensor: right exhaust pipe
•
connector: adjacent to the filter box, left
side
Electrical specifications:
Heater circuit: 12 -14
Ω
at 20 °C (68 °F)
Pin-out:
1. Sensor (pink wire)
2. Sensor signal - (green/white wire)
3. Heater ground (violet/white)
4. Heater power (red/brown cable)
ELECTRICAL ERRORS
Check the air-fuel ratio / right Lambda probe P0136
- short to positive / open circuit, short to negative
or carburetion excessively lean / signal not plausible for abnormal title correction or probe signal fault.
Error cause
Short-circuit to positive: excessive voltage at PIN 11 or PIN 12 of the control unit connector.
Open circuit or short-circuit to negative: interruption of the circuit or null voltage between control unit
connector PIN 11 and 12.
Troubleshooting
Short-circuit to positive:
