2000 stratus, the batt light comes and goes.. the alt was checked and ok, the batt tested ok, wiring looked ok, so far every thing looks good, charges 14.2 -14.5 volts with the dvom..I know the VR is in the pcm, but would that totaly stop charging/overcharging if the pcm was bad? also will the IAT/map sensor cause the light to go on off? No engine light, or codes, will a batt temp sensor do this as well, anyone have test info?

can a resister be installed to bypass this sensor? does this can have a batt temp sensor?
