I don't believe it has a knock sensor.
The cam sensor on a 2005 Chrysler Town and Country is on the passenger side top of the engine next to where the motor mount bracket attaches.
It is located on the side of the engine block. The purpose of the knock sensor is to retard engine timing When there is an engine noise. It is a rare case that one ever goes bad.
The crank sensor is mounted on the top rear of the transmission bell housing.
The egr position sensor is part of the valve. It does not have a flow sensor.
The egr position sensor is on the egr valve which is above the alternator on the passenger side of the engine.
On the catalytic converter
It is on the throttle body, opposite of where the cables attach.
It is part of the egr valve on the front pass side of the engine.
a 2003 Chrysler Town and Country does not have a mass airflow sensor.
It measures how far open the EGR valve is. It is built on the valve.
A 1997 Chrysler Town and Country does not have a governor pressure sensor.
the Spark/Knock Sensor is under the intake manifold. Driver side. Approximately 5-7 hour job.
