Code P1416 & P1637 How to Fix? I just bought my wife a 99 Trans Am ,Getting Codes,HP Tuners says P1416 Secondary Air Injection (AIR)System Bank 2 and P1637 Generator L-Terminal circuit. How do I fix these and are they any thing to worry about?
Thanks For the Help....

P1416 is nothing big...easiest way to "fix" it is remove the AIR system from the car, and turn the codes for it off.
P1637 though is the alternator...possibly some damage to it's wiring, or possibly something wrong with the alternator, or it could be the wrong alternator for the car.

BTW,.. Just a bit more info on my issue. (P1637 code) ... Battery has a charge. All the lights for the gauge cluster still light up, alarm works & headlamps raise and lower at normal speed. .... I can't hear the starter 'click' when I turn the key. .... Starter Fuse isn't blown... SHE JUST WON'T START!

Update: ... Removed the alternator and battery today. Took them to Autozone for testing. Both in good shape. Went down to the dealer, bought an exciter wire ($54.40!!!) and cut and spliced it in.... CAR STILL WON'T START!!! ... Still throwing the same damn code too (P1637) ... God Damit!!!!

The Duratester at AutoZone will not test the L Circuit wire if I understand how the L Circuit works correctly. I would advise you to buy the AutoZone alternator put it in, see if it works and if the code comes back simply pull the alternator clean it and return it. As far as it seems that shouldn't keep it from starting?
