Crankshaft speed sensor
Removing
1. Disconnect the negative battery terminal.
2. Disconnect the crankshaft sensor wires from the harness at the connector located in the engine compartment behind the battery.
3. The sensor is located on the mating surface between the cylinder block and the gearbox bell housing above the starter opening. Loosen and remove the bolt, then remove the sensor from the gearbox housing. If present, remove the gasket.
Installation

Coolant temperature sensor
Removing
5. Refer to chapter 1 and partially drain the cooling system. Make sure the startup key is turned off.
6. The coolant temperature sensor is screwed into the upper wall of the cylinder head on the left side of the engine. Do not confuse it with the temperature gauge sensor.
7. Disconnect the sensor wire from the connector.
8. Turn out the gauge from a head of cylinders and remove a sealing ring.
Installation
9. Installation is made in an order the return to an order of removal. When finished, add fluid to the cooling system.
Electronic control unit
Removing
10. Electronic system control unit (ELR) located in the rear of the engine compartment behind a false panel.

16. Disconnect the negative battery terminal.
17. On non-turbo engines, refer to paragraph 2 and remove the air cleaner assembly.
18. Disconnect the drive wires at the connector.
19. Loosen and remove the two screws on the back of the drive. Remove the appropriate brackets.
