1. O2 Sensor Issues: The XKR has multiple oxygen (O2) sensors, and a faulty sensor can trigger the check engine light.
2. Catalytic Converter Problems: A failing catalytic converter can cause an increase in emissions and illuminate the engine light.
3. Vacuum Leaks: Vacuum leaks can disrupt proper fuel and air mixture leading to an engine light.
4. Mass Airflow Sensor Issues: A faulty Mass Airflow Sensor (MAF) can cause incorrect fuel-to-air ratios, triggering the engine light.
5. Throttle body problems: A malfunctioning or dirty throttle body can lead to a check engine light.
6. Ignition Coil Failures: Failure in one or more of the ignition coils can cause engine misfires and activate the check engine light.
7. Coolant temperature sensor problems: A faulty coolant temperature sensor can lead to incorrect fuel mixture and an engine light.
8. Transmission problems: Issues within the automatic transmission can switch on the engine light in the XKR.
9. Fuel injector issues: Faulty or clogged fuel injectors can cause the check engine light to come on.
10. Evaporative Emission (EVAP) System Issues: Problems in the EVAP system can activate the engine light.
