14. CHECK FOR ENGINE OIL LEAKS

1. Start the engine, and check that there are no oil leaks after performing maintenance.

15. CHECK FOR ENGINE COOLANT LEAKS

CAUTION:

  Do not remove the radiator cap while the engine and radiator are still hot. Pressurized, hot engine coolant and steam may be released and cause serious burns.

1. Fill the radiator with coolant and attach a radiator cap tester.

1. Warm up the engine.

1. Using the radiator cap tester, increase the pressure inside the radiator to 118 kPa (1.2 kgf/cm2, 17.1 psi), and check that the pressure does not drop.
   If the pressure drops, check the hoses, radiator and water pump for leaks. If no external leaks are found, check the cylinder block and head.

16. INSPECT ENGINE IDLE SPEED AND IGNITION TIMING

1. Warm up and stop the engine.

   NOTICE:
     A warmed up engine should have an engine coolant temperature of over 80°C (176°F), have an engine oil temperature of 60°C (140°F), and the engine rpm should be stabilized.

1. Check the idle speed control system.

   1. Using SST, connect terminals TC and CG of the DLC3.

      SST
        09843-18040

   2. Start the engine at idle.

      NOTICE:
      1. Confirm the terminal numbers before connecting them. Connection with a wrong terminal can damage the engine.
      2. Turn off all electrical systems before connecting the terminals.
      3. When checking ISC function, the transmission should be in the neutral position.

   3. After connecting terminals (TC and CG), check that the engine speed changes to approximately 1,000 to 1,500 rpm for 5 seconds, and then returns to idle speed.
      If the result is not as specified, check the throttle body, DTC (Click here) and wire harness.

17. CHECK CO/HC

1. Start and warm up the engine.

1. Run the engine at 2,500 rpm for approximately 180 seconds and idle the engine.

1. Insert CO/HC meter testing probe at least 40 cm (1.3 ft.) into the tailpipe.

1. Check CO/HC concentration at idle.

   Idle CO concentration:
     0 to 0.5 %

   Idle HC concentration:
     Applicable local regulation

1. If the CO/HC concentration is not as specified, perform troubleshooting in the order given below.

   1. Check the heated oxygen sensor operation (Click here).

   2. See the table below for possible causes, and then inspect and repair the applicable causes if necessary.

   2. When pressing the accelerator pedal, check the operating sound of the running motor. Make sure that no friction noises emit from the motor.
      If friction noise is heard, replace the throttle body.

1. Check the throttle position sensor.

   1. Connect the intelligent tester to the DLC3.

   2. Turn the ignition switch ON.

   3. Under Current Data, check that the throttle valve opening percentage (Throttle Pos) is within the standard.

      Standard throttle valve opening percentage:
        60% or more

      NOTICE:
        When checking the standard throttle valve opening percentage, the shift lever should be in the N position.
      If the percentage is less than 60%, replace the throttle body.
