ON-VEHICLE SERVICE TSB Revision ENGINE MECHANICAL <2.4L ENGINE> 11A-9 WARNING Keep your distance from the spark plug hole when 5. Cover the spark plug hole with a shop towel etc., during cranking. After the engine has been cranked, check for 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 250 − 400 r/min): 1,275 kPa (185 psi) Minimum limit (at engine speed of 250 − 400 r/min): 959 kPa (139 psi) 8. Measure the compression pressure for all the cylinders, and check that the pressure differences of the cylinders are Limit: 98 kPa (14 psi) 9. If there is a cylinder with compression or a compression difference that is outside the limit, pour a small amount of (1) If the compression increases after oil is added, the cause of the malfunction is a worn or damaged piston ring and/ (2) If the compression does not rise after oil is added, the cause is a burnt or defective valve seat, or pressure is 10.Connect the crankshaft position sensor connector. 11.Install the spark plugs and spark plug cables. 12.Use the scan tool to erase the diagnostic trouble codes. NOTE: This will erase the diagnostic trouble code resulting MANIFOLD VACUUM CHECK M1111002700064 1. Start the engine and allow it to warm up until the temperature of the engine coolant reaches 80 − 95 ° C (176 −
203 ° F). 2. Connect a tachometer. 3. Attach a tee-fitting union to the vacuum hose between the fuel pressure regulator and the intake manifold plenum, and 4. Start the engine and check that idle speed is within specification. Then check the vacuum gauge reading. Idle speed: 700 ± 100 r/min Minimum limit: 60 kPa (18 in Hg) AKX01178 COMPRESSION AB AKX01179 VACUUM GAUGE AB |
