BMW DTC P0996 – Transmission Fluid Pressure Sensor/Switch ‘F’ Circuit Intermittent
DTC P0996 meaning on BMW
DTC P0996 on a BMW indicates an intermittent issue with the Transmission Fluid Pressure Sensor/Switch ‘F’ Circuit. This fault code is triggered when the powertrain control module (PCM) detects a variation in the signal from the transmission fluid pressure sensor or switch, specifically in circuit ‘F’.
BMW DTC P0996 symptoms
Symptoms of DTC P0996 on a BMW may include erratic shifting behavior, transmission slipping, harsh shifting, transmission overheating, or the transmission going into limp mode. The vehicle’s check engine light may also illuminate.
BMW DTC P0996 causes

BMW DTC P0996 seriousness
DTC P0996 should be addressed promptly to prevent further damage to the transmission system. Ignoring this fault code can lead to more severe transmission issues and potentially result in costly repairs.
How to diagnose DTC P0996 on BMW
To diagnose DTC P0996 on a BMW, a mechanic would typically start by using a diagnostic scan tool to retrieve the fault code and any related data. They would then inspect the transmission fluid pressure sensor/switch, check the wiring and connectors in circuit ‘F’ for damage, and perform a transmission fluid level and condition check.
Additional diagnostic steps may include testing the transmission fluid pressure sensor/switch for proper operation, checking the PCM for any related codes or issues, and conducting a thorough inspection of the transmission system for any other potential faults.
How to fix DTC P0996 on BMW
Fixing DTC P0996 on a BMW may involve replacing the transmission fluid pressure sensor/switch if it is found to be faulty. The mechanic may also need to repair or replace any damaged wiring or connectors in circuit ‘F’, ensure the transmission fluid level is correct, and perform a transmission fluid flush and refill if necessary.
If the PCM is determined to be the cause of the issue, it may need to be reprogrammed or replaced. Once the necessary repairs have been made, the fault code should be cleared, and the vehicle should be test-driven to ensure the issue has been resolved.
How to erase DTC P0996 on BMW
To erase DTC P0996 on a BMW, a mechanic can use a diagnostic scan tool to clear the fault code from the PCM’s memory. After the repair has been completed and the issue causing the fault code has been resolved, the mechanic can perform a code clearing procedure to erase the DTC P0996 from the system.
