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.
COMPRESSION PRESSURE INSPECTION
(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 (1 76-203°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 con- nector (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.

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):
Limit (at engine speed of 250-400 r/min): 1,350 kPa (192 psi)
min. 960 kPa (137 psi) (7) Measure the compression pressure for all the cylinders.
Verify difference between maximum and minimum read- ings 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.

of wear that in the timing belt. Caution Always turn the crankshaft clockwise.
(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 crank- shaft counterclockwise as it could cause inadequate belt tensioning.

INSTALLATION SERVICE POINTS F A 4 TIMING BELT INSTALLATION
(1) Align the timing marks on the camshaft sprocket and crankshaft sprocket. (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 pre- vent the belt from coming off when crankshaft is turned.
