P3190 on Toyota
Poor engine power on Toyota and Lexus hybrids
Severity: Inspect soon
The code means the gasoline engine is not producing proper power, and Toyota bulletins pair it with failed engine starts. The car may run on the electric motor for a while but can lose power.
It gets more serious if:
- Stop: Stop in a safe place if the car loses power, will not start the engine, or shows hybrid system warnings.
