• Install main bearing cap without main bearings insta lled, and tighten main bearing cap bolts to the specified
torque. Refer to EM-94, "
Disassembly and Assembly".
• Measure the inner diameter of main bearing housing using suitable tool.
• Measure the position shown [5 mm (0.20 in)] backward from main
bearing housing front side in the 2 directions as shown. The
smaller one is the measured value.
• If out of the standard, replace cylinder block and main bearing caps assembly.
NOTE:
Main bearing caps cannot be replaced individually, bec ause they are machined together with cylinder block.

round and taper at six different points on each cylinder. [(A) and (B)
directions at (C), (D), and (E)] [(A) is in longitudinal direction of
engine]
NOTE:

(d) at (a) and (b).
• If the measured value exceeds the limit, correct or replace crankshaft.
• If corrected, measure the bearing oil clearance of the corrected main journal and/or pin journal. Then select main bearing and/or connecting rod bearing. Refer to EM-125, "
Connecting Rod Bearing" and/or EM-124,
"Main Bearing".

< PRECAUTION >[HR16DE]
PRECAUTIONS
•
After performing each TROUBLE DIAGNOSIS, perform DTC
CONFIRMATION PROCEDURE or Component Function
Check. The DTC should not be displayed in the DTC Confir-
mation Procedure if the repair is completed. The Component
Function Check should be a good result if the repair is com-
pleted.
• When measuring ECM signals with a circuit tester, never allow
the two tester probes to contact.
Accidental contact of probes will cause a short circuit and
damage the ECM power transistor.
• Do not operate fuel pump when there is no fuel in lines.
• Tighten fuel hose clamps to the specified torque.
• Do not depress accelerator pedal when starting.
• Immediately after starting, do not rev up engine unnecessar-
ily.
• Do not rev up engine just prior to shutdown.

SYSTEM
*1: ECM determines the start signal status
by the signals of engine speed and battery voltage.
*2: This signal is sent to the ECM through CAN communication line.
SYSTEM DESCRIPTION
This mechanism hydraulically controls cam phases c ontinuously with the fixed operating angle of the intake
valve.
The ECM receives signals such as crankshaft position, camshaft position, engine speed, engine oil tempera-
ture and engine coolant temperature. Then, the ECM s ends ON/OFF pulse duty signals to the intake valve
timing (IVT) control solenoid valve depending on driving stat us. This makes it possible to control the shut/open
timing of the intake valve to increase engine torque in low/mid speed range and output in high-speed range.

SYSTEM DESCRIPTION
This mechanism hydraulically controls cam phases continuously with the fixed operating angle of the exhaust
valve.
The ECM receives signals such as crankshaft positi on, camshaft position, engine speed, engine oil tempera-
ture and engine coolant temperature. Then, the ECM s ends ON/OFF pulse duty signals to the exhaust valve
timing (EVT) control solenoid valve depending on driving stat us. This makes it possible to control the shut/
open timing of the exhaust valve to increase engi ne torque and output in a range of high engine speed.

scription

INPUT/OUTPUT SIGNAL CHART
SYSTEM DESCRIPTION
• The engine protection control at low engine oil pressure warns the driver of a decrease in engine oil pres-
sure by the oil pressure warning lamp a before the engine becomes damaged.
• When detecting a decrease in engine oil pressure at an engine speed less than 1,000 rpm, ECM transmits an oil pressure warning lamp signal to the combination meter. The combination meter turns ON the oil pres-
sure warning lamp, according to the signal.
