(13)Stop the engine, remove the jumper wire from the ignition timing adjustment connector (brown), and return the connector to its original condition. (14)Star-l the engine and check that ignition timing is at the standard value. Actual ignition timing: approx. 10"BTDC NOTE 1. Ignition timing is variable within about f7", even under normal operation. 2. And it automatically advances by about 5" from 10" BTDC at higher altitudes. CURB IDLE SPEED INSPECTION J 110003016 (1) Before inspection and adjustment verify in the following conditions: 0 Engine coolant temperature: 80-95°C (176-203°F) 0 Lights, electric cooling fan and all accessories: OFF 0 Transaxle: Neutral (P range on vehicles with NT) (2) Check the basic ignition timing. Adjust if necessary. Standard value: 5"BTDCk 2' (Except 1996 models and 1995 models for California) 5"BTDC f 3" (1996 models and 1995 models for California) (3) After turning the ignit'on switch to OFF, install the tachometer or connect the scan tool to the data link connector (white). For the method of installing the tachometer, refer to P.11A-10. (4) Start the engine and'run it at idle. (5) Run the engine at idle for 2 minutes. (6) Check the idle speed. Curb Idle speed: 750 k 100 r/min NOTE The idle speed is controlled automatically by the idle air control (IAC) system. (7) If there is a deviation from the standard value, refer to GROUP 13 - Check Chart Classified by Problem Symptoms, and check the MFI components. IDLE MIXTURE INSPECTION 110003017 (1) Before inspection, set the vehicle in the following condition. 0 Engine coolant temperature: 80-95°C (176-203°F) 0 Lights, electric cooling fan and accessories: OFF 0 Transaxle: Neutral (P range on vehicle with AlT) 11A-12 1.5L ENGINE - Service Adjustment Procedures (2) Make sure that the basic ignition timing is at a standard value. Standard value: 5"BTDC k 2" (Except 1996 models and 1995 models for California) 5"BTDC f 3" (1996 models and 1995 models for California) (3) After turning the ignition switch OFF, set a tachometer or connect the scan tool to the data link connector. NOTE For tachometer setting procedure, refer to P.1lA-10. (4) Start the engine and run at 2,500 r/min forapprox. 2 minutes. ( 5 ) Set the CO tester and HC tester. (6) Check the CO concentration and HC concentration with the engine at idle. Standard value: CO concentration: 0.5% or less HC concentration: 100 ppm or less (7) If the standard value is exceeded, check the following items. # 3. Diagnostic output Closed loop control (If closed loop control is performed normally, heated oxygen sensor output signals change within a 0-400 mV range and a 600-1,000 mV range.) Fuel pressure Injectors Ignition coil, spark plug cables and spark plugs Leaks in EGR system and EGR valve Evaporative emission control system Compression pressure NOTE If CO and HC concentrations exceed the respective standard values despite the fact that the results of the inspection made on all items are normal, replace the three-way catalyst. - a COMPRESSION PRESSURE INSPECTION 110003018 (1) Before inspection, check that the engine oil, starter and battery are normal. Also, verify to the following conditions: a Engine coolant temperature: 80-95°C (176-203°F) a Lights, electric cooling fan and all accessories: OFF a Transaxle: Neutral (P range on vehicle with A/T) (2) Remove all of the spark plugs. (3) Disconnect the 6-pin distributor connector (except 1995 models for California) or crankshaft position sensor connector (1995 models for California). NOTE Doing this will prevent the engine control module from carrying out ignition and fuel injection. (4) Cover the spark plug hole with a shop towel etc., and after the engine has been cranked, check that no foreign material is adhering to the shop towel. 1TSB Revision _ - . .- 1.5L ENGINE - Service Adjustment Procedures - . ...,. . 11A-13 Caution 1. Keep away from the spark plug hole when cranking. 2. During a compression test, if water, oil, fuel, etc., . has come from cracks inside the cylinder, these materials will become heated and will gush out from the spark plug hole, which is dangerous. (5) Set compression gauge to one of the spark plug holes. (6) Crank the engine with the throttle valve fully open and measure the compression pressure. Standard value (at engine speed of 250-400 rlmin): 1,350 kPa (192 psi) Limit (at engine speed of 250-400 r/min): min. 960 kPa (137 psi) (7) Measure the compression pressure for all the cylinders. Verify difference between maximum and minimum readings do not exceed the limit. Limit: max. 100 kPa (14 psi) ..-- (8) 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 (6) and (7). a. 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. b. 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. (9) Connect the distributor connector (except 1995 models for California) or crankshaft position sensor connector (1995 models for California). (1O)lnstall the spark plugs and spark plug cables. (11)Use the scan tool to erase the diagnostic trouble codes, or disconnect the battery ground cable for more than 10 seconds and reconnect it. NOTE This will erase the diagnostic trouble code resulting from the distributor connector being disconnected. MANIFOLD VACUUM INSPECTIONN 110003019 (1) Verify the following conditions before inspection. 0 Engine coolant temperature: 80-95°C (176-203°F) 0 Lights, electric cooling fan, and all accessories: OFF 0 Transaxle: Neutral (P range on vehicles with PJT) (2) Install the tachometer or connect the scan tool to the data link connector (white). (3) Disconnect the vacuum hose from the fuel pressure regulator. 1 TSB Revision I 11A-14 1.5L ENGINE - Service Adjustment Procedures ’ I (4) Connect a three-way vacuum tee between the removed 1 vacuum hose and the nipple and connect a vacuum gauge to the vacuum tee as shown. (5) Start the engine and check that idle speed is within the I standard value range. (6) Check the manifold vacuum. I Limit: 60 kPa (18 in.Hg) min. 1 1 I TIMING BELT TENSION ADJUSTMENT iiooo3ozo I The timing belt has an automatic tension adjusting mechanism. Adjustment can be made by the following procedure.

(8) Turn the crankshaft clockwise to bring the No. 1 cylinder piston to top dead center on the compression stroke. Caution For aligning the timlng marks, never turn the crankshaft counterclockwise as it could cause inadequate belt tensioning. 1 (9) Loosen both pivot side and slot side tensioner bolts and tension the belt, making use of the tensioner spring force. (10)Turn the crankshaft clockwise by two teeth of camshaft sprocket. ZlENC550 1 TSB Revision I 1.5L ENGINE - Service Adjustment Procedures 11A-15 (11) Push the timing belt tensioner inthe'direction of the arrow to check that each sprocket is kept in firm and complete engagement with the belt cogs. After this check, release hand pressure so that only the tensioner spring acts on belt and tighten the slot side bolt and then the pivot side bolt to fix the tensioner in position. - .. . -. . .. . .__ . . (12)Check the timing belt tension. Hold the timing belt tensioner and timing belt together by hand and give the belt a slight thumb pressure at a point level with tensioner center.

Caution Turn the crankshaft clockwise. 4 B b CAMSHAFT SPROCKET REMOVAL (1) Use the special tool to remove the camshaft sprocket with the timing belt attached. (2) Tie the camshaft sprocket and timing belt with a wire so that the position of the camshaft sprocket will not move with respect to the timing belt. 4 C b CYLINDER HEAD ASSEMBLY REMOVAL Using the special tool, loosen the bolts in the order shown in the illustration (in 2 or 3 steps), remove them and then remove the cylinder head assembly.

(Now the piston in No. 1 cylinder is at the top dead center on the compression stroke.) (2) Set the timing belt first on crankshaft sprocket and then keeping the tension side of belt tight, set on the camshaft sprocket. Caution If the timing belt is re-used, install so that the arrow marked on it at time of removal is pointing in the clockwise direction. (3) Apply counterclockwise force (in the direction B) to the camshaft sprocket to give tension to the belt on tension side and make sure that all timing marks are lined up. (4) Install the crankshaft pulley temporarily. This is to prevent the belt from coming off when crankshaft is turned. b B 4 TIMING BELT LOWER COVER /TIMING BELT UPPER COVER INSTALLATION Note that the timing belt lower and upper cover attaching bolts differ in size from one place to another.
