DTC P0130-00: Linear A/F Sensor circuit over-voltage
 
 
 
 
TECHNICAL DESCRIPTION
  • The ECM effects air-fuel ratio feedback control in accordance with the signals from the linear air-fuel ratio sensor.
  • If the linear air-fuel ratio sensor has deteriorated, corrections will be made by the heated oxygen sensor (rear).
 
 
DESCRIPTIONS OF MONITOR METHODS
If the air-fuel ratio detection signal has an abnormality although the linear air-fuel ratio sensor is sufficiently ready to operate, the DTC is set as a malfunction.
 
 
MONITOR EXECUTION
Continuous.
 
 
MONITOR EXECUTION CONDITIONS (Other monitor and Sensor)
Other Monitor (There is no temporary DTC set in memory for the item monitored below)
  • Linear air-fuel ratio sensor heater monitor
  • Misfire monitor
  • Fuel system monitor
Sensor (The sensor below is determined to be normal)
  • Mass airflow sensor
  • Engine coolant temperature sensor
  • Intake air temperature sensor
  • Barometric pressure sensor
  • Throttle position sensor
  • Fuel tank pressure sensor
 
 
DTC SET CONDITIONS
Logic Flow Chart
Check Conditions
  • 12V battery positive voltage is between 10.0 and 16.5 volts.
  • More than 180 seconds have passed since the engine starting sequence was completed.
Judgment Criteria
  • The Vs+ input voltage subtracted from the Ip+ input voltage is be lower than 0.6 volt or higher than 5.0 volts for 12 seconds.
 
 
FAIL-SAFE AND BACKUP FUNCTION
Does not control air-fuel ratio closed loop.
 
 
OBD-II DRIVE CYCLE PATTERN
Refer to Diagnostic Function, OBD-II Drive Cycle – Pattern 1 OBD- II DRIVE CYCLE.
 
 
TROUBLESHOOTING HINTS (The most likely causes for this code to be set are:)
  • Linear air-fuel ratio sensor failed.
  • Connector damage.
  • ECM failed.
 
 
DIAGNOSIS
Required Special Tools:
  • MB992744: Vehicle communication interface-Lite (V.C.I.-Lite)
  • MB992745: V.C.I.-Lite main harness A
  • MB992747: V.C.I.-Lite USB cable short
  • MB992748: V.C.I.-Lite USB cable long
1.STEP 1. Test the OBD-II drive cycle after replace the linear air-fuel ratio sensor.
After replacing the linear air-fuel ratio sensor and erasing the DTC, carry out test drive with the drive cycle pattern, and recheck the DTC.
(1) Replace the linear air-fuel ratio sensor (Refer to ENGINE, Engine, Motor and Emission Control – Emission Control – Exhaust Gas Purification System CATALYTIC CONVERTER REMOVAL AND INSTALLATION).
(2) Use scan tool (M.U.T.-III SE) to erase the DTC.
(3) Carry out test drive with the drive cycle pattern (Refer to Diagnostic Function, OBD-II Drive Cycle – Pattern 1 OBD- II DRIVE CYCLE).
(4) Use scan tool (M.U.T.-III SE) to recheck the DTC.
Q: Is DTC P0130-00 set?
Replace the ECM (Refer to ENGINE CONTROL MODULE (ECM) REMOVAL AND INSTALLATION).
The inspection is complete.
