P0975 — Shift Solenoid B Control Circuit Range/Performance

System: Powertrain  |  Type: Generic (OBD-II Standard)  |  Make: Generic

About P0975

P0975 is a generic (obd-ii standard) powertrain diagnostic trouble code. It belongs to the P-prefix family of codes, which covers engine, transmission, emissions, or fuel-system faults.

When P0975 is stored, the module has detected a plausibility fault — the measured value is in the electrical range but is not consistent with expected operating behaviour.

Scanning & clearing: A generic OBD-II scan tool will usually read and clear powertrain (P) codes. For live data, freeze-frame capture, and bi-directional tests you may need a more capable scan tool that supports the vehicle's ECM protocol.

Because P0975 is a generic OBD-II code, its base definition is shared across manufacturers. The specific diagnostic steps, reference values, and repair procedures can vary by vehicle, and the TaT Diagnostic Assistant includes verified procedures submitted by working technicians.

Code Information

The P0975 fault code is set when the control module detects a range or performance issue in the control circuit of Shift Solenoid B. This solenoid is important in the functioning of automatic transmissions, where it controls the flow of hydraulic fluid for the engagement or disengagement of gears. A range or performance problem in this circuit suggests that the operation of Shift Solenoid B or its control circuit is either not within the expected parameters set by the manufacturer or is not performing effectively. This could be due to a malfunctioning solenoid, wiring problems, or issues withi...
