I dont know anything about cars...these are the codes and their meanings but i dont understand which parts i need to have checked please help these are the codes and their meanings i'm sure someone could help me know where to start. p1404-egr valve pintle stuck open
p0118- engine coolant circuit high input p0404- exhaust gas recirculation circuit range/performance p0405-egr sensor a circuit low p0452- evaporative emission control system pressure sensor low input p0453- evaporative emission control system pressure sensor high input
Exhaust Gas Recirculation System Is the main problem here. the other code P0118 may be a bad temprature sensor or your thermostate needs to be changed. Last it could be a weak water pump.
So what is an EGR system and how does it work? EGR stands for Exhaust Gas Recirculation, and as its name implies, this system allows exhaust gasses from your car to be re-circulated into the engine, helping to reduce emissions. These systems are mostly comprised of the EGR valve, a DPFE (Delta Pressure Feedback EGR) sensor, hoses, a vacuum regulator, some vacuum lines, wiring, the computer and the exhaust tube leading to the valve itself.
The car's wiring can be tested in the normal fashion by looking for broken and lose wire, and all vacuum lines can be checked easily for cracks, leaks and correct routing.
The last thing i would then check is the the EGR valve, EGR vacuum regulator and DPFE sensor (or similar flow sensor).
I hope this helps and good luck

Engine Coolant Temperature Circuit Low Input
have a evaporative emission control code going off do they have to remove gas tank to replace? or is it an easy fix
