P0219 Engine Overspeed Condition
What does P0219 mean?
P0219 — Engine Overspeed Condition. This is an OBD-II diagnostic trouble code a scanner retrieves when your vehicle's computer detects engine overspeed condition. The level of risk depends on how the vehicle is currently running and how long you've been driving with the light on.
Common causes of P0219
- Unintended engine revving caused by a stuck throttle
- Faulty vehicle speed or engine speed sensor readings
- Transmission slippage or torque converter issue
- PCM detecting an implausible high RPM event
How to fix P0219
