Inspection And Adjustment Of Idle Speed Sfe

(See HINT on page FI-18)

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 vacuum lines connected

HINT: All vacuum hoses for EGR systems, etc. should be properly connected.

(e) EFI system wiring connectors fully plugged

(f) All operating accessories switched OFF

(g) Transmission in neutral range

2. CHECK ISC SYSTEM (See page FI-151)

3. CONNECT TACHOMETER (See page IG-21)

4. ADJUST IDLE SPEED

(a) Using SST, connect terminals TE1 and E1 of the check connector.

SST 09843-18020

HINT: Decrease the rpm after the engine maintains a speed of the 1,000 - 1,300 rpm for 5 seconds.

5. FURTHER CHECK IDLE SPEED

700 ± 50 rpm USA A/T 850 ± 50 rpm CANADA M/T 750 ± 50 rpm CANADA A/T

If the idle speed is not within these values, carry out either of the below listed procedures and then recheck the idle speed.

Carry out a driving test, including stop-go several times at a speed above 10 km/h, or start the engine, idle for 30 seconds and then turn the engine off repeatedly. By doing this, idle data will be stored in the ISC and the idle rpm will be at specified value.
