Please help me start looking in the right area....?

1996 Plymouth Grand Voyager 3.8L FWD:





I installed a new battery over a month ago and put on 3000 miles, but I have these OBDII codes that won't let me pass smog. everything passes.





OBDII Failing Monitors:


Catalyst (not ready)


Evaporative System (not ready)


Oxygen Heater Sensor (not ready)


Exhaust Gas Recirculation System (not ready)





MIL code(ignition light diagnostic):


12 = Battery disconnected within the last 50 key-cycles


55 = completed test|||could be an egr prob|||Take it to Autozone or some car parts place that will throw it on the diagnostic computer for free. A new battery has nothing to do with not passing smog.





You have a bad sensor and running the diagnostic will tell you which sensors/switches need replacing.|||This is going to be a bit of a pain, but you need to restart the van repeatedly until the system resets.





After you start the van a few doxen more times, it shoud read ok!|||You are apparently not completing the required drive cycle required for the obd 2 test environments. try driving down the highway for 10 or 12 miles, then decelerate without using brake and do some city driving on the way back, and quit clearing the codes( if you are)|||these are not obd codes. get correct codes for obd you'll make repairs much easier|||I have no idea, but am really interested to see what actually works. Here's a star.
