Where are the oxygen sensors on a 2005 Chrysler Town and Country?

What are the two sensors between the heater core and the thermostat housing on a 1994 Ford Escort LX Can they cause a low temp gauge and little or no heat. I replaced water pump and thermostat?
One is the temperature sending unit for the gauge and the other is the sending unit for the computer. The housing is called the water outlet. There is a plastic bypass valve that melts when the car overheats. It is inside the water outlet. If you changed your thermostat and still get no heat you need to replace this water outlet housing. There is no way to fix the plastic bypass. You have to replace the water outlet housing.

Which types of sensors are on the 2013 and 2010 aftertreatment paccar engine?
Specifically pertaining to the aftertreatment system, you have two NoX sensors.. one after the turbo, and one after the SCR outlet. Those will measure SCR catalyst conversion efficiency. There'll be three temperature sensors in the DPF itself, and there'll be the aftertreatment differential pressure sensor above the DPF, with two tubes going into the DPF. The system PACCAR uses is licensed from Cummins.
Where are the engine sensors on a 1992 Honda Accord located?

Where is the fan sensor on a 1998 Cavalier?

Should supply line coming out of hot water tank have a drop down leg in it to keep the tank from losing heat out the pipes?
No this is not necessary. Install the pipes as per usual. You can insulate the hot water pipes up to two meters or up to two yards from the hot water outlet from the hot water tank to prevent this.
