Error codes what do they mean

[gill2001]

I was driving my car and the ce light turn on and stayed on. I got the codes from the computer but what do they mean.
235
335
122
157
648
please help. My cars idle is too high when parked and when I rev it in park it soars and stays where I took off my foot off the gas. I just changed the MAF. I fixed a broken vacuum hose on the egr. I thinks it a green hose. I also bought a TPS and I put it on and it gave me the same results. I took off the new TPS and put the old one and it seem to do better. Sorry for the essay but i need to knwo what is happening. Please help the SHO FOOL shoot

235 seems to be an invalid code.

DTC 335
Exhaust gas recirculation valve pressure sensor voltage higher or lower than expected during KOEO self-test.

DTC 122
Throttle position sensor circuit below minimum voltage.

DTC 157
Mass air flow sensor circuit below minimum voltage.

DTC 648
Incorrect gear ratio obtained for fourth gear.

I would rerun the test to double check all the codes, write them all down and then reset the computer. If the codes come back than there will be a need to troubleshoot each sensor for the proper parameters.
