Installation is the reverse of removal, with caution to tighten the mounting bolt to the correct torque.

On 2014 and earlier 2.4L engines, the knock sensor is located on the side of the cylinder block in front of the starter, under the in-take manifold. On 2015 and later models, it is located at the front of the engine block, under the exhaust manifold. On V6 engines, the knock sensors are located in the valley between the cylinder heads. 2.7L and 3.5L engines have one knock sensor; 3.6L engines have two. On 3.6L engines, the sensor nearest the front of the engine is Sensor no. 1 and the sensor nearest the rear of the engine is Sensor no.Due to the work involved, both knock sensors should be replaced at the same time. To replace the knock sensor(s), relieve the fuel system pressure and drain the cooling system. Disconnect the negative battery cable. On 2007 2.7L engines, remove the cylinder head from the rear cylinder bank. On 2008 and later 2.7L engines and all 3.5L and 3.6L engines, remove the lower intake manifold. On 3.6L engines, also remove the engine oil filter housing. On 2.4L engines, remove the intake manifold (2014 and earlier) or the exhaust manifold (2015 and later). Disconnect the electrical connector(s) from the knock sensor(s). Remove the mounting bolt(s) and detach the sensor(s) from the engine block. Installation is the reverse of removal. Tighten the knock sensor to the specified torque. On V6 engines, refill the cooling system.
