Frequently asked questions about B0120
What does B0120 mean?
Fluid Reservoir Level Sensor E. The control module detected a fault associated with the Fluid Reservoir Level Sensor E circuit or function; the stored code identifies the affected component rather than a single failure mode.
Is B0120 generic or manufacturer-specific?
B0120 is a generic OBD-II code: it has the same meaning on every make and model that follows the SAE standard.
Can TuningBot remove B0120 at file level?
Not guaranteed. Powertrain (P) codes can be reliably disabled in the ECU calibration, but body, chassis and network codes depend on the specific control unit and how the fault is implemented - some can be handled, some cannot. Ask for a quote and our engineers will check your file and tell you, free of charge, whether B0120 is removable in your case.
