DTC P1140, P1145 IVT CONTROL POSITION SENSOR
Component DescriptionINFOID:0000000001326879
Intake valve timing control position sensors are located in the front of
cylinder heads in both bank 1 and bank 2.
This sensor uses a Hall IC.
The cam position is determined by the intake camshaft sprocket con-
cave (in four places). The ECM provides feedback to the intake valve
timing control for appropriate target valve open-close timing accord-
ing to drive conditions based on detected cam position.

NOTE:
If DTC Confirmation Procedure has been previously conduc ted, always turn ignition switch OFF and wait at
least 10 seconds before conducting the next test.
WITH CONSULT-III
1. Turn ignition switch ON.
2. Select “DATA MONITOR” mode with CONSULT-III.
3. Start engine and drive vehicle under the following conditions for at least 10 seconds.
4. Check 1st trip DTC.
5. If 1st trip DTC is detected, go to EC-1023, "
Diagnosis Procedure".
WITH GST
Follow the procedure “WITH CONSULT-III” above.

CYLINDER HEAD
2. Ream cylinder head recess diameter for service valve seat.
 Be sure to ream in circles concentric to valve guide center.This will enable valve to fit correctly.
3. Heat cylinder head to 110 to 130 °C (230 to 266 °F) by soaking in
heated oil.
4. Provide valve seats cooled well with dry ice. Force fit valve seat into cylinder head. WARNING:
Cylinder head contains heat. When working, wear protecti ve equipment to avoid getting burned.
CAUTION:
Avoid directly touching cold valve seats.
5. Using the valve seat cutter set (commercial service tool) or valve
seat grinder, finish seat to the specified dimensions. Refer to
EM-149, "
Standard and Limit".
CAUTION:
When using the valve seat cutter, firmly grip cutter handle
with both hands. Then, pr ess on the contacting surface all
around the circumference to cu t in a single drive. Improper
pressure on with cutter or cutting many different times may
result in stage valve seat.
6. Using compound, grind to adjust valve fitting.
7. Check again for normal contact. Refer to "VALVE SEAT CONTACT".
VALVE SPRING SQUARENESS
 Set a try square along the side of valve spring and rotate spring. Measure the maximum clearance between the top of spring and try
square.
 If it exceeds the limit, replace valve spring.

VALVE SEAT REPLACEMENT
When valve seat is removed, replace with
oversized [0.5 mm (0.020 in)] valve seat.
1. Bore out old seat until it collapses. Boring shoul d not continue beyond the bottom face of the seat recess
in cylinder head. Set the machine depth stop to ensure this. Refer to EM-266, "
Standard and Limit".
CAUTION:
Prevent to scratch cylinder head by excessive boring.
2. Ream cylinder head recess diameter for service valve seat.
 Be sure to ream in circles concentric to valve guide center.This will enable valve to fit correctly.
3. Heat cylinder head to 110 to 130 °C (230 to 266 °F) by soaking in
