Ω
at 20 °C (68 °F)
Pin-out:
1. Sensor (grey/white wire)
2. Sensor signal - (green/white wire)
3. Heater ground (white/yellow)
4. Heater power supply (white)
ELECTRICAL ERRORS
Check the air-fuel ratio / right Lambda probe P0130
- 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
Shorted to positive: excessive voltage at PIN 18 or PIN 12 of the control unit connector.
Circuit open or shorted to negative: interruption of the circuit or null voltage between control unit con-
nector PIN 18 and 12.
Troubleshooting
Shorted to positive:
•
Disconnect the control unit connector and the sensor connector.
•
Verify that there is no short to battery positive on sensor connector PIN 1 (corresponding to
control unit connector PIN 18); if there is a short, restore the cabling.
•
Verify that there is no short to battery positive on sensor connector PIN 2 (corresponding to
control unit connector PIN 12); if there is a short, restore the cabling.
The circuit is open:
•
Disconnect the control unit connector and the sensor connector.
•
Verify continuity of the cabling between the sensor connector and the control unit connector:
Control unit PIN 18 - sensor PIN 1 and control unit PIN 12 - sensor PIN 2. Restore the cabling
if necessary.
•
If the cabling is intact and the error persists, proceed with the following checks.
