Intake Valve Timing Control Position Sensor
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 primary cam sprocket
concave (in three places). The ECM provides feedback to the intake
valve timing control for appropriate target valve open-close timing
according to drive conditions based on detected cam position.

DTC Confirmation Procedure
EBS00LWR
CAUTION:
Always drive at a safe speed.
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.
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is between 10V and 16V at
idle.
PROCEDURE FOR MALFUNCTION A
With CONSULT-II
1.
Turn ignition switch “ON”.
2.
Select “DATA MONITOR” mode with CONSULT-II.
3.
Maintain the following conditions for at least 10 consecutive sec-
onds.
4.
Maintain the following conditions for at least 20 consecutive sec-
onds.
5.
If the 1st trip DTC is detected, go to
EC-151, "Diagnostic Procedure"
With GST
Follow the procedure “With CONSULT-II” above.
PROCEDURE FOR MALFUNCTION B
With CONSULT-II
1.
Turn ignition switch “ON”.
2.
Select “DATA MONITOR” mode with CONSULT-II.
3.
Maintain the following conditions for at least 10 consecutive sec-
onds.
4.
If the 1st trip DTC is detected, go to

Specification data are reference values and are measured between each terminal and ground.
Pulse signal is measured by CONSULT-II.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.
