Models with 2.0L SOHC engine – Bosch Motronic M1.5.4 system
Engine Control System Layout - 2.0L SOHC Engine
1. Idle speed control valve
2. Throttle potentiometer
3. Blow-off valve
4. Exhaust gas recirculation valve
5. Fuel pressure regulator
6. Ignition distribution module
7. Fuel pump relay
8. Fuel injection system relay
9. Electronic control unit
10. Crankshaft position sensor
11. Coolant temperature sensor
12. Fuel knock sensor
13. Air temperature sensor
14. Air flow sensor
These models are equipped with the Bosch Motronic engine management system. The system is controlled by an electronic control unit that receives information from various sensors.

2.5 and 3.0 liter engines – Bosch Motronic m².8.1 or 2.8.3 system
Location of engine control system components – 2.5L and 3.0L engines
1. Knock sensor for fuel combustion in cylinders located on the right side of the engine
2. Blow-off valve
3. Coolant temperature sensor
4. Ignition distribution module
5. Fuel pressure regulator
6. Solenoid valve
7. Switching flap
8. Idle speed control valve
9. Fuel pump relay
10. Fuel injection system relay
11. Electronic control unit
12. Knock sensor for fuel combustion in cylinders located on the left side of the engine
13. Camshaft position sensor
14. Air damper
15. Solenoid valve
16. Air flow sensor
17. Air temperature sensor
18. Exhaust gas recirculation valve
These models are equipped with the Bosch Motronic engine management system, similar to the Motronic system installed on models with a 2.0L SOHC engine. The main difference between this system and the Bosch Motronic system is the presence of a camshaft position sensor.
