  1. INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY Measure the resistance according to the value(s) in the table below. Standard Resistance Tester Connection Condition Specified Condition 1 - 2 20°C (68°F) 6.9 to 7.9 ohms If the result is not as specified, replace the camshaft timing oil control valve assembly. Check the operation. Connect a battery positive (+) lead to terminal 1 and negative (-) lead to terminal 2, and check the movement of the spool valve. *a Component without harness connected (Camshaft Timing Oil Control Valve Assembly) *b When Applied *c When Cut Off *d Spool Valve OK Condition Specified Condition Battery voltage is applied Valve moves in left arrow direction shown in illustration Battery voltage is cut off Valve moves in right arrow direction shown in illustration NOTE: Accumulation of foreign matter can cause minor pressure leaks. Minor pressure leaks in the intake side oil control valve will cause the intake camshaft to advance. Minor pressure leaks in the exhaust side oil control valve will cause the exhaust camshaft to retard. The inappropriate camshaft timing that results from these leaks will cause a DTC to be stored. If the result is not as specified, replace the camshaft timing oil control valve assembly.

  1. REMOVE FRONT NO. 1 CONSOLE BOX INSERT Refer to «PROCEDURE - Step 1»(ref-635616-S37412679762014070300000)
  2. DISCONNECT HEATED OXYGEN SENSOR CONNECTOR Remove the clip. Turn back the floor carpet. Disconnect the heated oxygen sensor connector.
  3. REMOVE FRONT CENTER FLOOR COVER LH Disengage the 5 clips to remove the front center floor cover LH.
  4. REMOVE HEATED OXYGEN SENSOR Disengage the clamp and remove the wire harness clamp bracket from the heated oxygen sensor. *1 Wire Harness Clamp Bracket Disengage the clamp and heated oxygen sensor grommet from the vehicle body. *a Grommet Using SST, remove the heated oxygen sensor from the front exhaust pipe assembly (TWC: Front and rear catalyst). SST: 09224-00010 NOTE: If the heated oxygen sensor has been struck or dropped, replace it.

  1. INSPECT HEATED OXYGEN SENSOR Measure the resistance according to the value(s) in the table below. *a Component without harness connected (Heated Oxygen Sensor) Standard Resistance Tester Connection Condition Specified Condition 1 (HT1B) - 2 (+B) 20°C (68°F) 11 to 16 ohms 1 (HT1B) - 4 (E2) Always 10 kohms or higher If the result is not as specified, replace the heated oxygen sensor.

  1. INSTALL HEATED OXYGEN SENSOR Using SST, install the heated oxygen sensor to the front exhaust pipe assembly (TWC: Front and rear catalyst). *a Length of SST 30 mm (1.18 in.) *b Length of Torque Wrench 260 mm (10.2 in.) SST: 09224-00010 without SST [Torque (N*m(kgf*cm, ft.*lbf))] Torque: 44 N*m (449 kgf*cm, 32 ft.*lbf) with SST [Reading of Torque wrench (N*m(kgf*cm, ft.*lbf))] Torque: 39 N*m (398 kgf*cm, 29 ft.*lbf) NOTE: If the heated oxygen sensor has been struck or dropped, replace it. HINT: This torque value is effective when SST is parallel to the torque wrench. The "with SST" torque value is effective when using SST with a fulcrum length of 30 mm (1.18 in.). The "with SST" torque value is effective when using a torque wrench with a fulcrum length of 260 mm (10.2 in.). If using a torque wrench with a different length, or connecting the torque wrench and SST at an angle, refer to the alternate torque values. Refer to «PRECAUTION [08/2013 - ]»(ref-635429-S26537304232014070300000) Engage the clamp and heated oxygen sensor grommet to the vehicle body. *a Grommet Install the wire harness clamp bracket to the heated oxygen sensor and engage the clamp. *1 Wire Harness Clamp Bracket
  2. INSTALL FRONT CENTER FLOOR COVER LH Engage the 5 clips to install the front center floor cover LH.
  3. CONNECT HEATED OXYGEN SENSOR CONNECTOR Connect the heated oxygen sensor connector. Install the floor carpet. Install the clip.
  4. INSTALL FRONT NO. 1 CONSOLE BOX INSERT Refer to «PROCEDURE - Step 9»(ref-635616-S39884561052014070300000)
  5. INSPECT FOR EXHAUST GAS LEAK
  1. INSPECT IG2 RELAY (IG2) Measure the resistance according to the value(s) in the table below. Standard Resistance Tester Connection Condition Specified Condition 3 - 5 Battery voltage not applied between terminals 1 and 2 10 kohms or higher Battery voltage applied between terminals 1 and 2 Below 1 ohms If the result is not as specified, replace the IG2 relay (IG2).
  2. INSPECT EFI-MAIN RELAY (EFI-MAIN) Measure the resistance according to the value(s) in the table below. Standard Resistance Tester Connection Condition Specified Condition 3 - 5 Battery voltage not applied between terminals 1 and 2 10 kohms or higher Battery voltage applied between terminals 1 and 2 Below 1 ohms If the result is not as specified, replace the EFI-MAIN relay (EFI-MAIN).
  3. INSPECT INJ RELAY (IGT/INJ) Measure the resistance according to the value(s) in the table below. Standard Resistance Tester Connection Condition Specified Condition 3 - 5 Battery voltage not applied between terminals 1 and 2 10 kohms or higher Battery voltage applied between terminals 1 and 2 Below 1 ohms If the result is not as specified, replace the INJ relay (IGT/INJ).
