The supplied evidence does not establish a specific failure mechanism, diagnostic threshold, or complete repair criteria for this code alone.
3. What system is affected?
High Flow Electric Oil Pump (HF EOP) / HP EOP motor-control-current diagnostic circuit or function, as described by Hyundai service communication 22-AT-009H.
4. How serious is this code?
Not yet established by verified evidence.
5. Symptoms you may notice
Not yet established by verified evidence.
6. Possible causes
- The verified service communication associates P1C2E4B with HP EOP motor control current and identifies the electric oil pump as the causal part in its warranty information. A more specific cause is not yet established by verified evidence.
7. Can I still drive the vehicle?
Not yet established by verified evidence.
8. Can I charge the vehicle?
Not yet established by verified evidence.
9. What you can safely do
