What it means
The clutch position has not been learned by the control system. This may occur when a required learn procedure has not completed successfully.
At a glance
- Usually lights the check-engine light
How it works
The transmission control module must learn the clutch position so it can match sensor readings to clutch movement. P080A sets when that learned position is missing or the required learning process has not completed successfully; a sensor, actuator, wiring, or module fault can prevent learning.
Common causes
Most likely first.
- Clutch position learn procedure not completed after service
- Learn procedure interrupted or unsuccessful
- Clutch position sensor or actuator fault
- Wiring or connector fault
- Control module calibration or circuit fault
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
How to diagnose it
- Scan the transmission module for related codes and save freeze-frame data and any recorded learn status before clearing codes.
- Check service history for recent clutch, actuator, sensor, or transmission work that may have left the position learn incomplete.
- Use a scan tool to check whether a clutch position learn is required, available, or recorded as unsuccessful.
- Inspect the clutch position sensor, actuator connectors, and wiring for damage, looseness, or corrosion before attempting a learn.
- If the learn fails again, compare sensor and actuator data with the manufacturer’s specification and diagnose the circuit or module fault indicated by related codes.
Common fixes
- Complete the required clutch position learn after confirming the transmission is ready for it.
- Repair wiring or connector faults affecting the clutch sensor or actuator.
- Replace a confirmed faulty clutch position sensor or actuator.
- Correct a verified module calibration or circuit fault, then repeat the learn.
Can I keep driving?
Avoid driving if the transmission shifts harshly, slips, or cannot engage gears, since the clutch control may not know the correct position. If shifting is normal, limit driving until the learn issue is resolved, as it can lead to poor engagement or a limited gear mode.
A code shows where the control module detected a fault, not always which part failed. Check the causes in order and confirm with a test before replacing parts. Have several codes? Check them together
This is a generic code: it means the same on every make. The car’s maker may add more detail in its own service information.
