Across
- 2. Ensures the fuel system maintains the correct pressure for optimal fuel delivery
- 4. Measures the temperature of the engine coolant
- 5. Provides data for adjusting the air-fuel ratio, as air density varies with temperature
- 6. Ensures the correct air-fuel ratio for efficient combustion and low emissions
- 8. Detects ignition pre-detonation
- 9. Uses valve position to change ignition timing
- 12. Detects how much pressure in in the manifold
- 15. Measures the air-fuel ratio more accurately than a standard O2 sensor
Down
- 1. Ensures proper lubrication and alerts the driver to potential low oil pressure issues
- 3. Monitor the position/rotational speed of the crankshaft
- 7. Helps control and reduce evaporative emissions from the fuel system
- 9. Measures the speed of the vehicle
- 10. Monitors air pressure in the tire
- 11. Monitors the position of the throttle valve
- 13. Manage turbocharger operation in turbocharged engines
- 14. Measures the amount of air entering the engine
- 16. Helps manage boost levels and protect the engine from overboost conditions
