6.Set compression gauge to
one of the spark plug holes. 7.Crank the engine with the throttle valve fully open and measure the compression pressure. Standard value (at engine speed of 200 r/min): 1,470 kPa Limit (at engine speed of 200 r/min): Minimum 1,000 kPa 8.Measure the compression pressure for all the cylinders, and check that the pressure differences of the cylinders are below the limit. Limit: Maximum 98 kPa 9.If there is a cylinder with compression or a compression difference that is outside the limit, pour a small amount of engine oil through the spark plug hole, and repeat the operations in steps from 6 to 8. (1) If the compression increases after oil is added, the cause of the malfunction is a worn or damaged piston ring and/or cylinder inner surface. (2) If the compression does not rise after oil is added, the cause is a burnt or defective valve seat, or pressure is leaking from the gasket. 10.Connect the crank angle sensor connector. 11.Install the spark plugs and tighten to the specified torque. Tightening torque: 25 ± 4 N·m 12.Install the ignition coils. 13.Install the engine air intake pipe. 14.Use the M.U.T.-III to erase the diagnosis codes.
