CHECKING THE ENGINE IDLING SPEED

TIP
Prior to checking the engine idling speed, the
throttle body synchronization should be adjusted
properly, the air filter element should be clean,
and the engine should have adequate compres-
sion.
1. Start the engine and let it warm up for several
minutes.
2. Check:
• Engine idling speed
Out of specification → Go to next step.
Engine idling speed
1250–1450 r/min
3. Check:
• ISC (idle speed control) learning value
"00" or "01" → Check the intake system.
"02" → Clean the ISC (idle speed control)
valve.
Refer to "CHECKING AND CLEANING THE
