Default Codes

B2721 and B2723.... i do have a small coolant leak that is running out the top of the coolant tank cap down the frame. could it possibly be shorting anything out?

anyone have the part number for a new coolant resevoir cap?? or know how much they cost?

Those codes have nothing to do with coolant or cooling system.
Are you getting a "no start" situation? Those codes have to do with your "PASS Key" (anti-theft) system. First try cleaning your ignition key (the resistor pellet) with alcohol and also carefully spraying a squirt of some contact cleaner into your ignition lock cylinder too. Work the key in/out and get everything dry, then see how it goes. I haven't looked up the codes in detail to see if they are indicating that your PASS key system may be inop or what.

BTW, if you've been in the habit (as many people do) of hanging a bunch of keys on your ignition key keyring, then don't. A lot of keys (i.e. weight) make life hard on an ignition lock cylinder from a wear and tear standpoint.

yes earlier today i couldnt get it to turn over. so best thing would be to try and clean the key with some rubbing alcohol? would it be better to possibly get a new key made?well on the way home tonight also the security light came on after about 40mins of driving but nothing happened.

There are a set of contacts in your ignition lock cylinder assembly that make contact with your resistor pellet on your key when you insert it. If those contacts are dirty, the PASS key system may not "recognize" your key and prevent you from starting the engine, just like it's supposed to do. It's just as important to clean the cylinder a bit with some contact cleaner (Radio Shack, etc) as it is to clean the key.
Try that and report back.

Man I was out yesterday too and got the B2723 C code, my car started and ran just fine after getting the code though. What is up with that? I plan to reset the code to clear it out, clean the key and see if it happens again.
