I have four CEL codes

1) P1445 = Purge Flow Circuit high input

2) P0600= The PCM has determined that a malfunction exisits in the serial commmunication line between the PCM and other module in the system.

3) P0110= The PCM has determined that a malfunction exists in the electrical circuit for the intake air temperature sensor. Input reading are at the either at the extreme bottom or top of the scale, indicating a possible wiring problem.

4) P0500= The PCM has detemined that a malfunction exists in the electrical circuit for the vehicle speed sensor

Anyone have an idea of how to fix these i think they sound so complex that i may have to take her to the dealer... I thought i got this car on a gret deal... think i was wrong... would ahve of these precent me from passing the emisssions inspection for New York State...
Or any New York York Maxima Enthuisast think they can fix these for a reasonable price...?

Thanks

Those codes will be tough to fix w/o a good scan tool which will allow access to various tests. The big one is the p0600. There is a communication BUS in which the various modules (ABS, Trans Module, SIR, ETC) will communicate. This code is usually set by either a break in a BUS wire, or sometimes a module that went bad will bring it down. A scan tool can tell you with what module the problem lies, at least it will tell you which module the ECM is not seeing. The p0500 says there is a problem with the VSS signal (vehicle speed sensor). That can be part of the BUS failure code, a broken wire or a bad sensor. Same thing with the p0110 and the p1445. Those codes have potential to be very tough to find, and you really need all the wiring diagrams and test procedures to effectively fix it. If you have a service manual, you can try looking into it, but you may be better bringing it to a pro. HTH

any know one a ball park price range for this repair

That is a tough one to price out because there are a lot of unknowns. Wiring problems on their own can take a while to find, and if any modules are bad they are expensive. A dealer will charge you a fee to diagnose them, with that they should be able to give you a price that is far more accurate than anything anyone here can give. Good luck
