P080A: Clutch Position Not Learned
After a clutch replacement or sensor replacement the TCM has not run a successful clutch-position learn cycle. Without learned end-stops the TCM cannot accurately command engagement points, leading to slipping or harsh take-up. A scan-tool guided learn procedure must be performed.
What P080A means
P080A is a generic OBD-II powertrain code in the transmission group.

Symptoms
- Check engine or transmission warning light on
- Harsh, delayed, or missing shifts
- Possible limp mode (locked in one gear)
- Slipping or shuddering during gear changes

Can I drive with P080A?
Usually yes, for a short time.
The car will often drive normally, but get it diagnosed soon. If you notice rough running, warning lights flashing, overheating or a burning smell, stop driving.
Why we rate it moderate
- Turns on the check engine light
Severity is our rule-based rating from the code’s flags in OBDex and the system it affects, not an inspection of your car. If the check engine light is flashing, or you notice overheating, low oil pressure, or brake or steering problems, stop driving and get help.
How to diagnose P080A
- 1
Confirm the code and save freeze-frame data
Read the codes with an OBD-II scan tool and note every code, not just P080A. Save the freeze-frame data (speed, load, temperature when the fault set) before clearing anything; it tells you when the fault happens.
- 2
Check for related codes first
Look for P0805. Related codes often share a cause; a circuit or sensor code usually needs fixing before a performance code like this one.
- 3
Check live data
Watch the related sensor and actuator readings in live data (Clutch position sensor A, TCM) and compare them with expected values in the service information for your vehicle.
- 4
Test the likely causes in order
Start with the most likely cause and work down: Learn cycle not performed after service. Test before replacing parts.
- 5
Check for recalls and service bulletins
Look up recalls for your exact vehicle with its VIN, and ask a dealer about technical service bulletins (TSBs). Manufacturers sometimes issue software updates or extended warranties for known faults.
- 6
Clear the code and verify the repair
After the repair, clear the code and drive the car under the conditions in the freeze-frame data to confirm it does not return.

P080A FAQ
What does P080A mean?
P080A means “Clutch Position Not Learned”. After a clutch replacement or sensor replacement the TCM has not run a successful clutch-position learn cycle. Without learned end-stops the TCM cannot accurately command engagement points, leading to slipping or harsh take-up. A scan-tool guided learn procedure must be performed.
Is P080A serious? Can I keep driving?
We rate P080A as moderate severity. Usually yes, for a short time. The car will often drive normally, but get it diagnosed soon. If you notice rough running, warning lights flashing, overheating or a burning smell, stop driving.
What causes P080A?
The most common causes, from most to least likely: Learn cycle not performed after service. Test before replacing parts, because several causes can set the same code.
How much does it cost to fix P080A?
Typical labor is about $40–$125 at an assumed $125/hour shop rate, plus parts. That is an estimate, not a quote: labor times and rates vary by vehicle and region, and diagnosis may be billed separately.
Can I fix P080A myself?
DIY difficulty is moderate. Most owners leave this to a shop because it needs involved testing or specialist tools. Always confirm the cause before buying parts.
Will P080A clear itself?
If the fault was intermittent, the warning may go off once the computer stops seeing it, but the code stays in memory. Fix the cause; clearing the code alone doesn’t repair anything.
