You have a burned Oxygen sencer, and the transmission pressure sencer is bad also. Your heater has a bad switchover circuit. Hope this helps.

P1166 Negative feedback from the 02 control,in better terminology its taking in false air,and it cant control it,The solution your engine has a MAF (Mass air flow), inspect this air duct for looseness,or cracks that can cause false air into the intake, this include the intake manifold gasket, and even the air filter condition.Something that can cause a lean condition from false air to low fuel pressure.But mainly false air.The location go to the front where the main engine pulley is at. (Some engine are transversed). You have 2 valve cover gasket the closet one to you is the first bank ,the one farthest away from you is the second bank,rule of thumb where cylinder number one is that is bank one.And sensor 1,the first sensor.
