P0970 — Pressure Control Solenoid C Control Circuit Low

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

About P0970

P0970 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 P0970 is stored, the module has detected a signal or supply voltage lower than the expected operating range.

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 P0970 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 P0970 fault code is set when the control module detects a low voltage condition in the control circuit of Pressure Control Solenoid C. This solenoid is integral to the functioning of the automatic transmission, where it modulates hydraulic pressure for effective gear shifting and control of the torque converter clutch. A low voltage condition in this circuit suggests an electrical issue, such as a short to ground, reduced voltage supply, or a fault within the solenoid itself. Low voltage can result in inadequate operation of Pressure Control Solenoid C, potentially causing transmission pro...
