hey if you truely think it is your egr valve unhook it and if that is the problem then when it is unhooked it should run better and the codes should not come up. hey if you cahnged the 1 o2 sensor and not the other you probably made the code for the one u repalced come up again. i would recommened that you change both of the o2 sensors at the same time. try checking if your catalatic convert is plugged. how you do this is take a dollar bill and hold it at the end of your tail pipe while it is idleing and if the dollar bill stays still you have a plugged catalatic converter.

SOURCE: How many sensors does a 1999 Saturn have

There is no "cam" sensor. The ignition module detects the timing of the cam based on spark demand from he cylinders. The common fix for this is to remove the ignition module, located under the ignition coils, and clean the mating surface on the transmission with a brillo pad until clean and smooth. Then reinstall the module.

I’m happy to assist further over the phone at

Code 452 is for a low voltage signal coming from the pressure sensor. The computer sends voltage to the sensor and expects a return voltage within a certain range.
If you have replaced the pressures sensor and the problem continues, it may be in the wiring between the computer and the sensor.

O2 sensor won't stop coming on.. All are replace but the bank2 sensor 2 keeps coming back on.. That sensor was replaced with OEM sensor but it's saying there high voltage as well.. Please help!!

The problem is not the o2 sensor.

-Check for misfire. (some partial fuel is not completly burn, so it go
pass the sensor) Tha's why it keep sending signal.
