IGNITION TIMING CHECK
M1111001700113
Required Special Tool:
MB991502: Scan Tool (MUT-II)
1. Before inspection, set vehicles in the following condition:
•
Engine coolant temperature: 80
−
95
°
C (176 - 203
°
F
)
•
Lights and all accessories: OFF
•
Transaxle: Neutral (P range on vehicles with A/T)
CAUTION
To prevent damage to scan tool MB991502, always turn the
ignition switch to the "LOCK" (OFF) position before
connecting or disconnecting scan tool MB991502.
2. Connect scan tool MB991502 to the data link connector.
3. Set up a timing light.
4. Start the engine and run it at idle.
5. Check that the idle speed is approximately 700 r/min.
6. Select scan tool MB991502 actuator test "item number 17."
7. Check that basic ignition timing is within the standard value.
Standard value: 5
°
BTDC
±
3
°
8. If the basic ignition timing is not within the standard value,
check the following items:
•
Diagnosis output
•
Timing belt cover and crankshaft position sensor installation
conditions
•
Crankshaft sensing blade condition
CAUTION
If the actuator test is not canceled, the forced drive will
continue for 27 minutes. Driving in this state could lead to
engine failure.
9. Press the clear key on scan tool MB991502 (select forced
drive stop mode), and cancel the actuator test.
10.Check that the actual ignition timing is at the standard value.
Standard value: Approximately 15
°
BTDC
NOTE: Ignition timing fluctuates about
±
7
°
Before Top Dead
Center, even under normal operating condition.
NOTE: It is automatically further advanced by about 5
°
to
15
°
Before Top Dead Center at higher altitudes.

°
BTDC
±
3
°
4. Start the engine and increase the engine speed to 2,500 r/
min for 2 minutes.
5. Set the CO, HC tester.
6. Check the CO contents and the HC contents at idle.
Standard value:
CO contents: 0.5% or less
HC contents: 100 ppm or less
7. If the CO and HC contents do not remain inside the standard
value, check the following items:
NOTE: Replace the catalytic converter when the CO and HC
contents do not remain inside the standard value, even
though the result of the inspection is normal for all items.
•
Diagnosis output
•
Closed-loop control (When the closed-loop control is carried
out normally, the output signal of the heated oxygen sensor
changes between 0
−
400 mV and 600
−
1,000 mV at idle.)
•

COMPRESSION PRESSURE CHECK
M1111002600067
1. Before inspection, check that the engine oil, starter and
battery are normal. Also, set the vehicle in the following
condition:
•
Engine coolant temperature: 80
−
95
°
C (176
−
203
°
F
)
•
Lights, and all accessories: OFF
•
Transaxle: Neutral (P range on vehicles with A/T)
2. Disconnect the spark plug cables.
3. Remove all of the spark plugs.
4. Disconnect the crankshaft position sensor connector.
NOTE: Doing this will prevent the engine control module
from carrying out ignition and fuel injection.
WARNING
Keep your distance from the spark plug hole when
cranking. Oil, fuel, etc., may spray out from the spark
plug hole and may cause serious injury.
5. Cover the spark plug hole with a shop towel etc., during
cranking. After the engine has been cranked, check for
foreign material adhering to the shop towel.
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):
824 kPa (119 psi)
Minimum limit (at engine speed of 250
−
400 r/min):
575 kPa (83 psi)
8. Measure the compression pressure for all the cylinders, and
check that the pressure differences of the cylinders are
below the limit.
Limit: 98 kPa (14 psi)
