- Faulty oxygen sensor
- Vacuum leak
- Fuel pressure regulator issue
- Malfunctioning fuel injector
- Wiring or connector problem
Symptoms of P2198 2010 Toyota Camry
- Decreased fuel efficiency
- Rough idling or stalling
- Engine hesitation or misfiring
- Check Engine Light illuminated
- Increased emissions
