WARNING: This page does not describe the selected car, but rather 31 other vehicles, including the 2018 Lincoln Navigator, 2018 Lincoln MKZ, 2018 Lincoln MKX, 2018 Lincoln MKT, and 2018 Lincoln MKC. However, it is still accessible from the selected car via links, so may be relevant.
- DTC: P050E Cold start engine exhaust temperature too low
- Monitor execution: Once per driving cycle, during the first 15 seconds of a cold start
- Monitor sequence: None
- Monitoring duration: Data gathering occurs during the first 15 seconds of a cold start. The decision to set P050E is made 300 seconds after start. This delay gives time for other diagnostics (for example, misfire monitor) to determine if another DTC should set instead of P050E.
