electrical problems

i'm having a number of problems. first of all every sensor on the engine seems to be bad, according to the OBD2 tool. and the a/c seems to be bad. i can't believe every sensor would be going bad all at the same time. i suspect an electrical problem. if i have a bad ECM would that cause the issues?

...a bad scan tool maybe? If every sensor was shot the engine would not run. Possibly check for a loose/bad ground for the PCM or DLC.

check battery terminals for corrosion,loose fitting

perform a voltage drop test at all the grounds

got an alarm...or sound system...inspect the wiring

wiggle the key while scanning the pcm
