DTC P2014 TUMBLE CONTROL VALVE POSITION SENSOR





Component Description











Tumble control valve position sensor is built into the tumble control valve actuator (3).

The sensor consists of a permanent magnet and Hall IC. It senses the valve shaft movement and feeds the voltage signals to the ECM.




CONSULT-III Reference Value in Data Monitor Mode

On Board Diagnosis Logic









DTC Confirmation Procedure

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 more than 11 V at idle.
1. Start engine and let it idle for 5 second.
2. Check 1st trip DTC.
3. If 1st trip DTC is detected, go to SEE Diagnosis Procedure.




Wiring Diagram





Specification data are reference values and are measured between each terminal and ground.
Pulse signal is measured by CONSULT-III.

CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in damage to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.









Diagnosis Procedure
1.CHECK GROUND CONNECTIONS
1. Turn ignition switch OFF.





2. Loosen and retighten ground screws on the body. For California.
