Code Definition

P080C — 1-4 upshift (skip shift) solenoid circuit too low

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

About P080C

P080C 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 P080C 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 P080C 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 P080C fault code is triggered when the Engine Control Module (ECM) or Transmission Control Module (TCM) detects a voltage level in the 1-4 upshift (skip shift) solenoid circuit that is below the expected range. This solenoid is part of the transmission control system and is specifically designed to facilitate the vehicle's ability to skip from 1st to 4th gear under certain conditions, typically in manual transmissions for efficiency purposes. A voltage too low in this circuit often suggests a partial short, high resistance, or a fault in the wiring or connectors leading to reduced voltage ...
