STEP 1. Check the right bank linear air-fuel ratio sensor.
(1) Disconnect the right bank linear air-fuel ratio sensor connector.
(2) Measure the resistance between right bank linear air-fuel ratio sensor connector power supply line and terminal LHFR.Standard value: 2.3 - 4.2 ohms [at 20°C (68°F)]
Is the measured resistance between 2.3 and 4.2 ohms [at 20°C (68°F)]?
Go to Step 2. Replace the right bank linear air-fuel ratio sensor. Then go to Step 5.
STEP 2. Check of harness damage in power supply line between MFI relay connector and right bank linear air-fuel ratio sensor connector.
STEP 3. Check of harness damage in LHFR line between right bank linear air-fuel ratio sensor connector and ECM connector 34.
STEP 4. Check the trouble symptoms.
STEP 5. Test the OBD-II drive cycle.
(1) Carry out a test drive with the drive cycle pattern. Refer to Diagnostic Function - OBD-II Drive Cycle - Pattern 3 . (2) Check the diagnostic trouble code (DTC).
Is DTC P0053 set?
Retry the troubleshooting. The inspection is complete.
