Hey guys, I was driving home before and all of sudden may check engine light came on so i pulled over and got the codes. I need some help with this. Im confussed.

1. code 12- Direct Battery input to PCM disconnected within last 50 ignition key-on cycles. Normal if battery has been disconnected, otherwise check battery power and ground connections.

2. code 25- A short is detected in one or more of the idle air motor circuits

3. code 15- No signal received from the vehicle speed sensor during road load operation ( which i dont get because its still working. )

4. code 42- Open or short in the ASD relay wiring or connectors

can someone tell me what the hell went wrong. the truck still drives fine. [sm=headbang.gif][sm=helpout.gif]
