Nissan Altima 2007-2012 Service Manual: P2014 tumble control valve position sensor
Description
Tumble control valve position sensor is built into the tumble control valve actuator (2).
1 : Intake manifold adapter
3 : Tumble control valve
The sensor consists of a permanent magnet and Hall IC. It senses the valve shaft movement and feeds the voltage signals to the ECM.

DTC CONFIRMATION PROCEDURE
1.PRECONDITIONING
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 11V at idle.
>> GO TO 2.
2.PERFORM DTC CONFIRMATION PROCEDURE
1. Start engine and let it idle for 5 seconds.
2. Check 1st trip DTC.
Is 1st trip DTC detected? YES >> Go to EC-414, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis Procedure
1.CHECK GROUND CONNECTION
1. Turn ignition switch OFF.
2. Check ground connection E9. Refer to Ground Inspection in GI-45, "Circuit Inspection".
Is the inspection result normal? YES >> GO TO 2.
NO >> Repair or replace ground connection.
2.CHECK TUMBLE CONTROL VALVE POSITION SENSOR POWER SUPPLY CIRCUIT-I
1. Reconnect ECM harness connector disconnected.
2. Turn ignition switch ON.
3. Check the voltage between tumble control valve actuator harness connector and ground.
Is the inspection result normal? YES >> GO TO 8.
NO >> GO TO 3.
3.CHECK TUMBLE CONTROL VALVE POSITION SENSOR POWER SUPPLY CIRCUIT-II
1. Turn ignition switch OFF.
2. Disconnect ECM harness connector.
3. Check the continuity between tumble control valve actuator harness connector and ECM harness connector.
Is the inspection result normal? YES >> GO TO 4.
NO >> Repair open circuit.
4.CHECK TUMBLE CONTROL VALVE POSITION SENSOR POWER SUPPLY CIRCUIT-III
Check harness for short to power and short to ground, between the following terminals.
Is the inspection result normal? YES >> GO TO 5.
NO >> Repair short to ground or short to power in harness or connectors.
5.CHECK COMPONENTS
Check the following.

DTC DETECTION LOGIC
With the Air/Fuel Mixture Ratio Self-Learning Control, the actual mixture
ratio can be brought closely to the
theoretical mixture ratio based on the mixture ratio feedback signal from the
A/F sensors 1. The ECM calculates
the necessary compensation to correct t ...
P0137 HO2S2
Description
The heated oxygen sensor 2, after three way catalyst (manifold),
monitors the oxygen level in the exhaust gas on each bank.
Even if switching characteristics of the air fuel ratio (A/F) sensor 1
are shifted, the air-fuel ratio is controlled to stoichiometric, by the signal
from t ...
