Upshift/Skip Shift Solenoid Control Circuit Range/Performance
What it means
P080B means the control circuit for the upshift/skip-shift solenoid isn't performing as expected. On manual-transmission cars this solenoid forces a 1st-to-4th "skip shift" for fuel economy under light load. A range/performance fault usually just disables that feature or turns on the light, without affecting how the car otherwise drives. Common causes are a faulty solenoid, wiring or connector damage, or an aftermarket skip-shift bypass.
Can I keep driving? Usually harmless to driving — the skip-shift (forced 1-to-4) feature may stop working or the light comes on; safe to drive and repair at your convenience.

How to diagnose & fix
Work through it in order
- Read freeze-frame data and confirm the code with a scan tool.
- Check whether an aftermarket skip-shift eliminator is installed — a common cause of this code.
- Inspect the solenoid connector and wiring for damage, shorts, or corrosion.
- Test the solenoid current draw and resistance against spec; replace if out of range.
- Check the related fuse and relay. Clear and retest.
