P134A86 — Invalid network signal values
Quick answer
P134A86 indicates that the motor controller received invalid data on the vehicle network, so motor output may be limited.
What to check first
- Read all stored fault codes with a scan tool and deal with related codes first.
- High-voltage system: do not open or disconnect high-voltage components. Refer the car to a technician qualified for high-voltage work.
Can I still drive?
Have it inspected before further driving. If in doubt, park the car and ask a technician — a fault that limits power or shuts the high-voltage system down will not clear by itself.
