P080B — 1-4 upshift (skip shift) solenoid circuit out of range

About P080B

P080B 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 P080B 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 P080B 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 P080B fault code is set when the Engine Control Module (ECM) or Transmission Control Module (TCM) detects that the circuit for the 1-4 upshift (skip shift) solenoid is operating outside of its expected range. This solenoid is responsible for controlling the transmission's ability to skip from 1st directly to 4th gear, a feature often found in manual transmissions for improved fuel efficiency under certain conditions. An 'out of range' condition can indicate issues such as abnormal voltage readings, resistance levels outside the normal specifications, or general signal inconsistencies withi...
