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 camshaft sprocket con-
cave (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.
CONSULT-II Reference Value in Data Monitor ModeNBS0042P
Specification data are reference values.
On Board Diagnosis LogicNBS0042Q
FAIL-SAFE MODE
When the malfunction is detected, the ECM enters fail-safe mode.

DTC Confirmation ProcedureNBS0042R
CAUTION:
Always drive at a safe speed.
NOTE:
If DTC P0011 or P0021 is displayed with DTC P0075, P0081, P1140 or P1145, first perform the trou-
ble diagnosis for EC-851
or EC-1159 .
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 1st trip DTC is detected, go to EC-830, "
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 1st trip DTC is detected, go to EC-830, "
Diagnostic Procedure"
.
With GST
Follow the procedure “With CONSULT-II” above.
