HINT
After running the engine at 1000 to 1300 rpm for 5 seconds, check that it returns to idle speed.
(6) Disconnect terminals 13 (TC) and 4 (CG) of the DLC3.
(7) Inspect the ignition timing at idle.
Standard ignition timing:
0 to 16 degrees BTDC
(8) Confirm that the ignition timing advances when the engine rpm is increased.
Remove the timing light.
Install the No. 2 cylinder head cover Installation.
7. INSPECT ENGINE IDLE SPEED
(a) Put the engine in inspection mode Component Tests and General Diagnostics.
(b) Warm up and stop the engine.
(c) When using the Techstream:
(1) Connect the Techstream to the DLC3.
(2) Put the engine in inspection mode Component Tests and General Diagnostics.
(3) Turn the Techstream on.
(4) Enter the following menus: Powertrain / Engine and ECT / Data List / Engine Speed.
HINT
Refer to the Techstream operator's manual for further details.
(5) Inspect the engine idle speed.
Standard idle speed:
950 to 1050 rpm
NOTICE:
* Turn all electrical systems and the A/C off.
* Inspect the idle speed with the cooling fans off.
* When checking the idle speed, the shift position neutral (N) or park (P) should be selected.
(6) Turn the power switch off.
(7) Turn the Techstream off.
(8) Disconnect the Techstream from the DLC3.
(d) When not using the Techstream:

(2) Put the engine in inspection mode Component Tests and General Diagnostics.
(3) Inspect the engine idle speed.
Standard idle speed:
950 to 1050 rpm
NOTICE:
* Turn all electrical systems and the A/C off.
* Inspect the idle speed with the cooling fans off.

NOTICE:
The measurement must be done as quickly as possible.
HINT
* Noise may be emitted from the transmission. However, this is not a malfunction.
* Always use a fully charged battery to obtain an engine speed of 200 rpm or more.
Standard compression pressure:
813 kPa (8.3 kgf/cm2, 118 psi) or more
Minimum pressure:
617 kPa (6.3 kgf/cm2, 89.5 psi)
Pressure difference between each cylinder:
100 kPa (1.0 kgf/cm2, 14.5 psi) or less
NOTICE:
* Inspect the other cylinders in the same way.
* Measure the compression as quickly as possible.
(7) If the cylinder compression is low, pour a small amount of engine oil into the cylinder through the spark plug hole, then inspect it again.
HINT
* If adding oil increases the compression, the piston rings and/or cylinder bore may be worn or damaged.
* If the pressure stays low, a valve may be stuck or seated improperly, or there may be leaks from the gasket.
(e) Install the 4 spark plugs Installation.
NOTICE:

(e) Check the CO/HC concentration while idling and when the engine is running at 2500 rpm.
HINT
When doing a 2 mode (with the engine idling/ running at 2500 rpm) test, the measurement procedures are determined by applicable local regulations.
If the CO/HC concentration does not comply with the regulations, troubleshoot in the order given below.
(1) Check the DTCs Reading and Clearing Diagnostic Trouble Codes.
(2) See the table below for possible causes, then inspect the applicable parts and repair them if necessary.
