Engine Error Codes

I need to get my Jeep to pass emissions, I need it to not have a check engine light on. One of my errors from Autozone's test is:

P1492
APLSOL Solenoid Circuit Malfunction

Can anybody give me any details on this? Thanks

I have a 97 XJ, 4.0, automatic

This site says: "Ambient/Batt Temp Sen Volts Too High."
Whatever the heck that means.

What part of the emissions did you fail on?

he posted on ifsja.org that he failed because he has an "engine light on". visual inspection i guess.

They wouldn't pass it for the check engine light. When I checked the test myself, I got the batt temp, and other misc things. But when I had Autozone hook up thier computer, they gave me errors about my tranny and the APLSOL solenoid, which sofar, not one person in the world knows what it is.

my 98 had some odd codes about the trans when the backup lite fuse was blown, #10 i think the manuel was wrong about the fuse.

I asked my friend at the Jeep parts dept. about this. He had not heard of a aplsol solenoid, so he asked the service manager about the error code p1492. It is a failure in the battery temperature sensor. In some XJs there is a temperature sensor built into the bottom of the plastic battery tray. If the sensor went bad, or the cable to it is cut/damaged/unplugged, it will give that error code. It could even be a battery that is overheating and going bad. After the problem is fixed, you might need to have the error code reset with a scan tool again.

that's actually what it was. I hate autozone. I found the connector, reconnected it, and wow, no check engine light anymore. Thanks for your help
