P1092 INFINITI Possible Causes
- Faulty VVEL control shaft position sensor, bank 2
- VVEL control shaft position sensor, bank 2 harness is open or shorted
- Poor electrical connection in the VVEL control shaft position sensor circuit, bank 2
- Faulty VVEL control module
How to Fix P1092 INFINITI Code?
Start by checking the “Possible Causes” listed above. Visually inspect the corresponding wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector pins.
Possible Symptoms
Engine Light On (or Service Engine Soon Warning Light)
Symptoms:
- Malfunction Indicator Lamp (Check Engine Light) illuminated
- Loss of power
- Rough idle
- Engine stalling
Causes:
- Faulty VVEL position sensor
- Faulty sensor wiring
- Problem with the VVEL control module
- Problem with the ECU (Engine Control Unit)
Diagnostic:
Diagnosing the P1092 code requires an OBD-II scan tool and a multimeter. A mechanic can use the scan tool to read the fault codes and view live data from the VVEL sensor. The multimeter can be used to test the voltage and resistance of the sensor and wiring.
Repair:
Repairing the P1092 code depends on the cause of the problem.
- Faulty VVEL position sensor: The sensor must be replaced.
- Faulty sensor wiring: The wiring must be repaired or replaced.
- Problem with the VVEL control module: The control module must be replaced.
- Problem with the ECU: The ECU must be reprogrammed or replaced.
Tips:
- If you have the P1092 code, it is important to have it diagnosed and repaired as soon as possible.
- Not fixing the problem can lead to more serious engine damage.
- You can find more information about the P1092 code on online forums and automotive repair websites.
P1092 INFINITI Meaning
VVEL (Variable Valve Event & Lift) is a system that continuously controls the valve event and valve lift. The rotational movement of the drive shaft equipped with an eccentric cam is transmitted to the output cam via the rocker arm and two types of links to push the intake valve down. The Engine Control Module (ECM) decides the target valve lift based on driving conditions and sends the control signal to the VVEL control module. The VVEL control module controls the rotation of the control shaft using the VVEL actuator motor and changes the movement of the output cam by moving the link pivot point. As a result, the valve lift changes continuously to improve engine power and response.
The VVEL control shaft position sensor (1) is placed on the VVEL actuator sub-assembly and detects the position angle of the control shaft. A magnet is pressed into the arm on the edge of the control shaft.
The magnetic field changes as the magnet rotates with the arm, causing a change in the sensor’s output voltage. The VVEL control module detects the actual position angle via the voltage change and sends the signal to the ECM.
