I keep getting this code B2264H and it says that It's a vertical position sensor.................I don't know what that means, can someone please tell me what that means and if it is serious? Thank you.

 

It means your posture is terrible

 

DTC B2264 Vertical Position Sensor Circuit

Circuit Description
The LH Door Control Module (LDCM) receives a vertical position signal from the LH mirror vertical position sensor. This signal is used by the LDCM for memory recall functions to determine the vertical position of the LH mirror. The LDCM commands the mirror memory settings based upon the voltage level the LDCM receives back from the vertical position sensor. The LDCM provides a 5 volt supply, a signal, and a ground to the vertical position sensor. The vertical position sensor is a variable resistor which the LDCM monitors the voltage level across. When a memory setting is recalled, the LDCM will command the LH mirror motor in the appropriate direction until the stored position sensor voltage level is achieved. The LDCM also monitors the LH mirror vertical position signal circuit and can determine if the voltage level received is out of range. If the voltage level is out of range, then a malfunction is present and a DTC will set.

Conditions for Setting the DTC
The LDCM detects LH mirror vertical position sensor signal voltage range under 0.1 volts or over 4.78 volts.
Condition must be present for 2 seconds.
Action Taken When the DTC Sets
Stores a history DTC B2264 in the LDCM memory.
This DTC can only be set as a history code even if the malfunction is current.
No driver warning message will be displayed for this DTC.
Conditions for Clearing the DTC
The LDCM detects the correct LH mirror vertical position sensor signal voltage range (0.1-4.78 volts) for longer than 2 seconds.
Use the IPC clearing DTCs feature.
Use a scan tool.
Diagnostic Aids
The following conditions may cause an intermittent malfunction:
There is an intermittent open or short (to ground or voltage) in LH mirror reference, signal, or ground circuit.
The LH mirror vertical position sensor is open or shorted internally.
If the LDCM is unable to determine the correct vertical position, manual power mirror functions will still operate, but the LDCM will not be able to recall the correct mirror memory settings.
Using a scan tool, select LDCM Data display and monitor the mirror vertical position data. Move the LH power mirror vertically in both direction while monitoring the vertical position sensor data. The voltage range should vary and stay between 0.1-4.78 volts depending on the direction of the mirror. This checks if the mirror vertical position sensor is open or shorted in different positions.
If the DTC does not reset after the code is cleared, then the problem may be intermittent. Perform the tests shown while moving related wiring and connectors. This can often cause the malfunction to occur. Refer to Intermittents and Poor Connections .
