P080D — 1-4 upshift (skip shift) solenoid circuit too high

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

About P080D

P080D 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 P080D is stored, the module has detected a signal or supply voltage higher 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 P080D 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 P080D fault code is set when the Engine Control Module (ECM) or Transmission Control Module (TCM) detects a voltage in the 1-4 upshift (skip shift) solenoid circuit that is higher than the expected range. This solenoid is an integral part of the transmission system in vehicles equipped with manual transmissions, enabling the transition from 1st directly to 4th gear under certain driving conditions to enhance fuel efficiency. A high voltage condition in the solenoid circuit typically points to a short to power or an issue within the solenoid control circuitry, leading to abnormally high vol...
