Standard value: 5° BTDC+/-3°
4. Start the engine.
5. Run the engine at idle for 2 minutes.
6. Check the idle speed. Select item number 22 and take a reading of the idle
speed.
Curb idle speed: 680+/-100 r/min
7. If the idle speed is outside the standard value, refer to MULTIPORT FUEL
INJECTION (MFI) DIAGNOSIS
.
IDLE MIXTURE CHECK Required Special Tool:
MB991958: Scan Tool (MUT-III Sub Assembly)
MB991824: V.C.I. MB991827: MUT-III USB Cable MB991910: MUT-III Main Harness A
1. Before checks set the vehicle in the following condition:
Engine coolant temperature: 80 - 95°C (176 - 203°F) Lights and all accessories: OFF Transaxle: P range
NOTE: The idle speed is controlled automaticall
y by the idle air
control system.
NOTE: Vehicles for Canada, the headlight, taillight, etc. remain
lit even when the lighting switch is in "OFF" position

output signal of the heated oxygen sensor changes between 0 - 400 mV and
600 - 1,000 mV at idle.) Fuel pressures Injector Ignition coil, spark plug EGR system and EGR valve leak Evaporative emission system Compression pressure
COMPRESSION PRESSURE CHECK Re
