IDLE SPEED
INSPECTION
1. INITIAL CONDITIONS
(a) Engine at normal operating temperature
(b) Air cleaner installed
(c) All pipes and hoses of air induction system connected
(d) All accessories switched OFF
(e) All vacuum lines properly connected
HINT:
All vacuum hoses for EGR system, etc. should be properly connected.

(g) Ignition timing check correctly
(h) Transmission in neutral position
2. CONNECT TOYOTA HAND±HELD TESTER OR OBDII SCAN TOOL (See page EM±10)
3. INSPECT IDLE SPEED
(a) Race the engine speed at 2,500 rpm for approx. 90 seconds.
(b) Check the idle speed.
Idle speed: 700 ± 50 rpm
If the idle speed is not as specified, check the IAC valve and air intake system.
4. DISCONNECT TOYOTA HAND±HELD TESTER OR OBDII SCAN TOOL
