Tightening torque 9 Nm
Attach ground cable to engine control unit - tightening torque 10 Nm / 7 lbf. ft.
Connect both wiring harness plugs to engine control unit and lock - ensure correct seating of wiring harness plugs.
Note. Before assembling components of the intake system (hoses, connections, etc.), they must be cleaned of any possible contamination (grease, oil, etc.). When tightening the hose clamps, be sure to observe exactly the tightening torque of 3.5 Nm / 2.6 lbf. ft.
Caution
It is only ensured that the intake system is free of leaks, thus ensuring operational safety of the engine, if the hose clamps are tightened correctly to the prescribed tightening torque.
