hey i just purchased my first Galant, its a 2002 LS V6.
i paid an unbelievable price and for the most part i love the car so far...
the check engine light is on and i have a reader, codes are as follows
P0141 - HO2S-12 (Bank 1 Sensor 2) Heater Circuit Malfunction
p0431 - Warmup Catalyst Efficiency Low (Bank 2)
P0403 - EGR Control Solenoid Circuit Malfunction.
so i bought the bank 1 sensor 2 o2 the other day have yet to install, but is it possible the egr could be causing the 02 codes? or vice versa. i just dont wanna replace a part thats not broken.
also for the p0403, will i need an egr or just the egr vacuum solenoid??? autozone sells the solenoid for half the price of the egr valve
any help would be appreciated...
