TROUBLE DIAGNOSIS - SPECIFICATION VALUEPFP:00031
DescriptionUBS00QBR
The specification (SP) value indicates the tolerance of the value that is displayed in “DATA MONITOR (SPEC)”
mode of CONSULT-II during normal operation of the Engine Control System. When the value in “DATA MONI-
TOR (SPEC)” mode is within the SP value, the Engine Control System is confirmed OK. When the value in
“DATA MONITOR (SPEC)” 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
MIL.
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 cor-
rection)

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)
Testing ConditionUBS00QBS

Vehicle driven distance: More than 5,000 km (3,107 miles)

Barometric pressure: 98.3 - 104.3 kPa (1.003 - 1.064 kg/cm2 , 14.25 - 15.12 psi)

Atmospheric temperature: 20 - 30°C (68 - 86°F)

Engine coolant temperature: 75 - 95°C (167 - 203°F)

Transmission: Warmed-up
–A/T and CVT models: After the engine is warmed up to normal operating temperature, drive vehicle until
“FLUID TEMP SE” (A/T or CVT) fluid temperature sensor signal) indicates more than 60°C (140°F).
–M/T models: After the engine is warmed up to normal operating temperature, drive vehicle for 5 minutes.

Electrical load: Not applied
–Rear window defogger switch, air conditioner switch, lighting switch are OFF. Steering wheel is straight
ahead.

Engine speed: Idle
Inspection ProcedureUBS00QBT
NOTE:
Perform “DATA MONITOR (SPEC)” mode in maximum scale display.
1. Perform EC-70, "
Basic Inspection" .
2. Confirm that the testing conditions indicated above are met.
3. Select “B/FUEL SCHDL”, “A/F ALPHA-B1” and “MAS A/F SE-
B1” in “DATA MONITOR (SPEC)” mode with CONSULT-II.
4. Make sure that monitor items are within the SP value.
5. If NG, go to EC-134, "

DTC P0075 IVT CONTROL SOLENOID VALVEPFP:23796
Component DescriptionUBS00QCT
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.

Specification data are reference values.
On Board Diagnosis LogicUBS00QCV
DTC Confirmation ProcedureUBS00QCW
NOTE:
If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and
wait at least 10 seconds before conducting the next test.
WITH CONSULT-II
1. Turn ignition switch ON.
2. Select “DATA MONITOR” mode with CONSULT-II.
3. Start engine and let it idle for 5 seconds.
4. If 1st trip DTC is detected, go to EC-176, "
Diagnostic Procedure"
.
WITH GST
Following the procedure “WITH CONSULT-II” above.

CONNECTING ROD BEARING OIL CLEARANCE
Method by Calculation

Install connecting rod bearings (2) to connecting rod (3) and
connecting rod bearing cap (1), and tighten connecting rod bolts
to the specified torque. Refer to EM-81, "
ASSEMBLY" for tight-
ening procedure.

Measure the inner diameter of connecting rod bearing with an
inside micrometer.
(Bearing oil clearance) = (Connecting rod bearing inner diame-
ter) – (Crankshaft pin journal diameter)

If clearance exceeds the limit, select proper connecting rod bearing according to connecting rod big end
diameter and crankshaft pin journal diameter to obtain specified bearing oil clearance. Refer to EM-88,
"HOW TO SELECT 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 speci-
fied torque. Refer to EM-81, "
ASSEMBLY" for the tightening procedure.
CAUTION:
Never rotate crankshaft.

Remove connecting rod cap and bearing, and using the scale
(A) on the plastigage bag, measure the plastigage width.
NOTE:
The procedure when the measured value exceeds the limit is
same as that described in the “Method by Calculation”.
MAIN BEARING OIL CLEARANCE
Method by Calculation

Install main bearings (3) to cylinder block (1) and main bearing
cap (2), and tighten main bearing cap bolts to the specified
torque. Refer to EM-81, "
ASSEMBLY" for the tightening proce-
dure.

Measure the inner diameter of main bearing with a bore gauge.
(Bearing oil clearance) = (Main bearing inner diameter) – (Crank-
shaft main journal diameter)
A : Example
B : Inner diameter measuring direction
Standard : 0.037 - 0.047 mm (0.0015 - 0.0019 in)

If clearance exceeds the limit, select proper main bearing according to main bearing inner diameter and
crankshaft main journal diameter to obtain specified bearing oil clearance. Refer to EM-91, "
HOW TO
SELECT MAIN BEARING" .
Method of Using Plastigage

Remove engine oil and dust on crankshaft main journal 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 main bearings to cylinder block and main bearing cap, and tighten main bearing cap bolts to the
specified torque. Refer to EM-81, "
ASSEMBLY" for the tightening procedure.
CAUTION:
Never rotate crankshaft.

Remove main bearing cap and bearings, and using the scale (A)
on the plastigage bag, measure the plastigage width.
NOTE:
The procedure when the measured value exceeds the limit is
same as that described in the “Method by Calculation”.
MAIN BEARING CRUSH HEIGHT

When main bearing cap is removed after being tightened to the
specified torque with main bearings (1) installed, the tip end of
bearing must protrude (B). Refer to EM-81, "
ASSEMBLY" for
the tightening procedure.

If the standard is not met, replace main bearings.
CONNECTING ROD BEARING CRUSH HEIGHT

When connecting rod bearing cap is removed after being tight-
ened to the specified torque with connecting rod bearings (1)
installed, the tip end of bearing must protrude. Refer to EM-81,
"ASSEMBLY" for the tightening procedure (B).

If the standard is not met, replace connecting rod bearings.: 0.012 - 0.022 mm (0.0005 - 0.0009 in)
