Throwing 3 codes...
My SES light came on so i had the codes scanned and they are P0122, P0452 and P1416.
P0122: TPS pedal position sensor cir. low input..... I'm sure this has something to do with my nitrous system i just installed. I had to get a TPS signal so i tapped into the TPS wire off the cars PCM.
P0452: Evap emission control system pre sensor low......I have no idea what this means.
P1416: Malfunction secondary air injection system bank #1 diag.....
Can you guys help me figure out how to fix these problems. The car runs good but i just would like to get these taken care of.
Thanks

secondary air is the air pump, its the thing under your car (if its lifted up) to the right of the air dam facing the front of the car, where there is the black plastic, something might be clogging it ..etc
evap is with the fuel tank/lines and such?? i think.... help me on this one

I had P1416 before, it was a clogged air check valve on the passenger side - easy to check/replace yourself. Don't know why the scanner said bank 1 diag, it's actually bank 2 - bank 1 would be P1415.

It's the black disc shaped valve in between the metal air tube coming off the exhaust manifold/then connects to the air hose, just above the #4 cyl coil. There's one just like it on the drivers side but further back towards the firewall. Disconnect the clamp, remove hose, then use two wrenches to unscrew it from the metal pipe. Some people replace both valves when one goes bad.

Well, you could look up the TPS and EVAP codes/diagnostics at gearchatter.com assumes you're stock though.
