About P0758

P0758 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 P0758 is stored, the module has detected an electrical-circuit fault in the wiring, connector, or driver associated with the named component.

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 P0758 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 P0758 fault code is set when the Transmission Control Module (TCM) detects an electrical problem in the Shift Solenoid B circuit, also known as the 2-3 shift solenoid. This solenoid is responsible for controlling hydraulic fluid flow to actuate shifts between second and third gear in the transmission. An electrical issue in this circuit can be due to several factors, including a malfunctioning solenoid, issues with the wiring, or problems within the TCM itself. The presence of this fault can lead to symptoms like improper or failed shifting between second and third gears, harsh or erratic ...
