2004 galant cat converter replaced now engine knocks

compression test cyclinder may have cracked head or warped head .I think that car has an Astron motor from my memory which has an alloy head that can warp or crack if the engine has been overheated ?

O2 sensors are always after the cat converter and HO2S sensors are always before the cat converter.
p0135 refers to heated oxygen sensor(HO2S) 1 bank 1-heater control--circuit malfunction
If it is a straight 6 cylinder engine with 2 cat converters it will be the sensor before the cat converter that connects to the manifold from pistons 1.2.3
If it is a V6 it will be the sensor that is in front of the cat converter that connects to the rear bank pistons 1.2.3. Use the special socket when removing/replacing the sensors to prevent wiring damage

code p0733 refers to gear 3 -incorrect ration===causes---wiring---TR sensor/switch--shift solenoids---transmission mechanical fault
code p0420 refers to catalytic converter system -bank 1---efficiency below threshold===causes--cat converter--wiring--HO2s 2
code po430 refers to cat converter system bank 2--efficiency below threshold===causes--cat converter--wiring ---HO2s 2
code p0328 refers to knock sensor (KS) 1 bank 1--high input===causes--wiring short to positive--KS incorrectly tightened--KS---ECM

basically replace the cat converters as they are blocking the exhaust system and preventing your over 45mph problem
replace the TR sensor/ switch as you have not mentioned a transmission problem
Rectify the problem with the KS as it controls the air/fuel mixture setting which contributes to the car getting hot.

code p 0432 is main cat converter bank 2 --efficiency below threshold ===causes -- cat converter---wiring heated oxygen sensor (HO2S ) in the bank 2 manifold before the cat converter
ave a compression test done to determine inlet valve seat insert loose
if you have a problem with it there should be a bit of a miss, or it should change with rpm
could be a cam lobe failing and the noise should change with rpm

Solenoid is your problem, the solenoid is connected to the (EGR) exhaust gas resirculation, when the solenoid fail, the EGR don't work right, and your O2 sensor on the cat is reading to much exhaust gases in the cat, so your catalytic converter is failing, solution go to a junkyard and get one from other engine or similar the looks clean and replaced, run your car for more than 10 miles and your service soon engine light should go off, if that don't append your O2sensor on the cat is no good.

this would be the top sensor before the cat closer to the engine back by the firewall

Bank one sensor is going to be in the front of your catalytic converter and bank two will be to the rear of it. This way your ECM knows how well the cat is working. It will read the oxygen content before the cat and then after.

this code relates to catalytic converter efficiency, could be a bad o2 sensor, bad cat , prob gonna need a mechanic to diagnose, if you do decide to replace o2 sensor you want to change the one behind cat, tghis one monitors cat function

There are 2 catalytic converters on Sedonas, it sounds like the rear one is failing. These can be replaced with generic universal ones that can be found on ebay, don't let the dealership tell you otherwise. Any number of shops would install it for you if you brought it in to them, if you don't want to install it yourself.

Despite the fact that it may be running fine right now, It sould be replaced, however. A faulty catalytic converter will result in the vehicle's computer adjusting fuel/air mixtures, timing, etc. etc. in an effort to rectify what is percieves to be an inefficient engine operation.

I have an '01 Galant ES USA. I got an engine code & quot;P0135 O2 Sensor Heater Circuit (Bank 2 Sensor 1) & quot;P0443-Evap Emiss Control System. Purge Control Valve Ciro. I need a good service centre that can fix this for me and do the servicing of the engin. Can anyone give me a hint?
