Code No. P0130: Linear A/F Sensor Circuit Over-voltage
FUNCTION
- The engine-ECU effects air/fuel ratio feedback control in accordance with the signals from the linear A/F sensor.
- If the linear A/F sensor has deteriorated, corrections will be made by the oxygen sensor (rear).
TROUBLE JUDGEMENT
Check Conditions
- Battery positive voltage is more than 10 V and is less than 16.5 V.
- More than 220 seconds have passed since the engine starting sequence was completed.
Judgement Criteria
- The Vs+ input voltage subtracted from the Ip+ input voltage is be lower than -2.1 V or higher than 2.3 V for 12 seconds.
- The pumping current is be lower than 0 mA or higher than 0 mA for 12 seconds.
FAIL-SAFE AND BACKUP FUNCTION
- Does not control air-fuel ratio closed loop.
PROBABLE CAUSES
- Failed linear A/F sensor
- Loose connector contact
- Failed engine-ECU
DIAGNOSIS PROCEDURE
STEP 1. Replace the linear A/F sensor
- After replacing the linear A/F sensor, reconfirm whether the diagnosis code is set.
Is the diagnosis code set?
Replace the engine-ECU.
Check end.
