CO/HC
INSPECTION
HINT:
This check is used only to det ermine whether or not the idle CO/
HC complies with regulations.
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 systems, etc. should be properly
connected.
(f) SFI system wiring connectors fully plugged
(g) Ignition timing set correctly
(h) Transmission in neutral position
(i) Tachometer and CO/HC meter calibrated by hand
2. START ENGINE
3. RACE ENGINE AT 2,500 RPM FOR APPROX. 180 SE-
CONDS
4. 4.INSERT CO/HC METER TESTING PROBE AT LEAST
40 cm (1.3 ft) INTO TAILPIPE DURING IDLING
5. IMMEDIATELY CHECK CO/HC CONCENTRATION AT IDLE AND/OR 2,500 RPM
HINT:
When doing the 2 mode (2,500 rpm and idle) test, follow the
measurement order prescribed by the applicable local regula-
tions.

IGNITION TIMING
INSPECTION
1. WARM UP ENGINE
Allow the engine to warm up to normal operating temperature.
2. CONNECT TOYOTA HAND −HELD TESTER OR OBD II
SCAN TOOL
(a) Remove the fuse cover on the instrument panel.
(b) Connect the TOYOTA hand−held tester or OBD II scan tool to the DLC3.
(c) Please refer to the TOYOTA hand−held tester or OBD II scan tool operator’s manual for further details.
3. CONNECT TIMING LIGHT TO ENGINE
4. CHECK IDLE SPEED
(a) Race the engine speed at 2,500 rpm for approx. 90 se- conds.
(b) Check the idle speed. Idle speed: 650 ± 50 rpm
5. INSPECT AND ADJUST IGNITION TIMING
(a) Using SST, connect terminals TE1 and E1 of the DLC1. SST 09843−18020
(b) Using a timing light, check the ignition timing. Ignition timing: 3 ° BTDC @ idle
(Transmission in neutral position and A/C OFF)
(c) Loosen the hold−down bolt, and adjust by turning the dis-
tributor.
(d) Tighten the hold− down bolt, and recheck the ignition tim-
ing.
Torque: 18 N·m (180 kgf·cm, 13 ft·lbf)
(e) Remove the SST from the DLC1. SST 09843−18020
6. FURTHER CHECK IGNITION TIMING Ignition timing: 2 − 13° BTDC @ idle
(Transmission in neutral position and A/C OFF)
HINT:
The timing mark moves in a range between 2 ° and 13° .
7. DISCONNECT TIMING LIGHT FROM ENGINE
8. DISCONNECT TOYOTA HAND −HELD TESTER OR
OBD II SCAN TOOL
