It's for the EGR valve - exhaust gas recirculation

Thermostat? engine cooling?
2 engines, here, LYA adn LY7.
nobody here posts engine, why do that?
so ill post only for 1.
the LA1
here are the steps.
NO FSM Sux huh? nor an alldata.com account, why not that? 15 bucks?

sigh.....
why not log in to alldata.com
read the page then ask ques tons that are not clear.
and next time post the engine type.
above is just 1 engine.

I just seen this post..after i wrote on the other post..Check the two hoses on the DPFE sensor..They connect to a pipe that comes off the exhaust..If you have a broken hose it will set this code..If the hoses are fine take off the hoses and run a small peice of wire to unclogg the the lines on the pipe..After that crank the vehicle and see if you feel any exhaust come out..then reconnect the hoses...If the hose is broke,,replace it with silicone hose,,regular vacuum hose or fuel hose will not hold up

Check this procedure, according with the repair guide for...

2.3L and 2.4L Engines
(see Figure 9)

1. Disconnect the negative battery cable
   
2. Detach the oxygen sensor connector.
   
3. Properly drain the engine coolant into a suitable container. Remove the heater hose from the thermostat housing for more complete coolant drain.

If your shure that a hose is on wrong then there is a place it goesonto that is also wrong . Two wromgs. The only place that a hse could be on wrong is at the exhaust asperater tube that hooks the EGR vavle to the exaust manifold. The heater hoses hook next to each other behind the engine going though the firewall. Follow these hoses back to the motor and see that they don't connect to the pipe on the lower left side of the exaust manifold. If its doing that remove it and see if you can find another hose the same size that will reach the exhaust tube and connect it and vise versa connect the other hose there. The Hoses can be alright though and the engine has a bigger problem a blown head gasket or cracked head. On some models the catalist converter has a hose hooked to it remove it and see itf water comes out, if shouldn't but if it does follow it back to the engine and unhook it there. If water ( Coolant comes out ) ( You may Have to add coolant not water to the cooling system to tell ) then this connection should be connected to a heater hose that you found going thogh the firwall. If you still dont find the problem and the cooling system holds presure and the water coming out the tailpipe is coolant and the engine runs OK ( I dought it). All engines produce a little water when running mainly when run shortly and not warmed up, it will appear black in color and not smell like antifreze. A prankster could have put the garden hose or man hose up the tailpipe to worry you some suspect those that helped point out the water in the first place. The exhaust hoses hook up to the air cleaner housing and pipe and the water hoses hook to the firewall a pipe on the back of the block and a short pipe hooked to the water pump. Repair manuels have pictures of the hoeses in the cooling system chapters.
