TROUBLE DIAGNOSIS - SPECIFICATION VALUE
DescriptionINFOID:0000000001161755
The specification (SP) value indicates the tolerance of the value that is displayed in “SPEC” of “DATA MONI-
TOR” mode of CONSULT-III during normal operation of the Engine Control System. When the value in “SPEC”
of “DATA MONITOR” mode is within the SP value, the Engine Control System is confirmed OK. When the
value in “SPEC” of “DATA MONITOR” mode is NOT within the SP value, the Engine Control System may have
one or more malfunctions.
The SP value is used to detect malfunctions that may affect the Engine Control System, but will not light the
MI.
The SP value will be displayed for the following three items:
 B/FUEL SCHDL (The fuel injection pulse width programmed into ECM prior to any learned on board correc-
tion)
 A/F ALPHA-B1 (The mean value of air-fuel ratio feedback correction factor per cycle)
 MAS A/F SE-B1 (The signal voltage of the mass air flow sensor)

P1111 IVT CONTROL SOLENOID VALVE
P1111 IVT CONTROL SOLENOID VALVE
DescriptionINFOID:0000000001161851
Intake valve timing control solenoid valve is activated by ON/OFF
pulse duty (ratio) signals from the ECM.
The intake valve timing control solenoid valve changes the oil
amount and direction of flow through intake valve timing control unit
or stops oil flow.
The longer pulse width advances valve angle.
The shorter pulse width retards valve angle.
When ON and OFF pulse widths become equal, the solenoid valve
stops oil pressure flow to fix the intake valve angle at the control
position.

CRANKSHAFT PIN JOURNAL DIAMETER
 Measure the outer diameter of crankshaft pin journal with a micrometer.
 If out of the standard, measure the connecting rod bearing oil clearance. Then use undersize bearing.
OUT-OF-ROUND AND TAPER OF CRANKSHAFT
 Measure the dimensions at four different points as shown in the
figure on each main journal and pin journal with a micrometer.
 Out-of-round is indicated by the difference in dimensions between
“X” and “Y” at “A” and “B”.
 Taper is indicated by the difference in dimension between “A” and
“B” at “X” and “Y”.
 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.
CRANKSHAFT RUNOUT
 Place a V-block on a precise flat table to support the journals on
the both end of crankshaft.
 Place a dial indicator (A) straight up on the No. 3 journal.
 While rotating crankshaft, read the movement of the pointer on the
dial indicator. (Total indicator reading)
 If it exceeds the limit, replace crankshaft.
CONNECTING ROD BEARING OIL CLEARANCE
Method by Calculation
 Install connecting rod bearings to connecting rod and cap, and tighten connecting rod bolts to the specified
torque. Refer to EM-101, "
Disassembly and Assembly".
 Measure the inner diameter of connecting rod bearing with an
inside micrometer.
(Bearing oil clearance) = (Connecting rod bearing inner diameter)
– (Crankshaft pin journal diameter)
 If the clearance exceeds the limit, select proper connecting rod
bearing according to connecting rod big end diameter and crank-
shaft pin journal diameter to obtain the specified bearing oil clear-
ance. Refer to EM-117, "
Connecting Rod Bearing".
Method of Using Plastigage
 Remove engine oil and dust on crankshaft pin and the surfaces of each bearing completely.
 Cut a plastigage slightly shorter than the bearing width, and place it in crankshaft axial direction, avoiding oil
holes.
 Install connecting rod bearings to connecting rod and cap, and tighten connecting rod bolts to the specified
torque. Refer to EM-101, "
Disassembly and Assembly".
CAUTION:Standard : Refer to EM-127, "

same as that described in the “Method by Calculation”.
MAIN BEARING OIL CLEARANCE
Method by Calculation

ified torque. Refer to EM-101, "
Disassembly and Assembly".
 Measure the inner diameter of main bearing with a bore gauge.

shaft main journal diameter)
 If the clearance exceeds the limit, select proper main bearing
according to main bearing inner diameter and crankshaft main
journal diameter to obtain the specified bearing oil clearance.
Refer to EM-119, "
MainBearing".
Method of Using Plastigage
 Remove engine oil and dust on crankshaft main journal and the surfaces of each bearing completely.
