i have a 1996 chevy 2500 extended cab, long bed that has been running fine but the service engine light has just come on. the codes that were processed out are as follows; PO157, Bank sensor 2 (PO700), P1192 (transmission control sensor) and it said "sensor circuit, low voltage". if anyone knows what any of these codes mean please help!
Thanks,
Big C

 

157 is right side downstream sensor (behind the cat) (why GM uses multiple sensors, O2, crank ect. is for aftermarket thief sales imo) The other is transmission, any issues with the truck?

 

no it runs fine, they were driving about 630 miles and then the light came on about 450-500 miles through.

 

Auuuuuuu,might be wrong here.BUT-I thought this was a section for problems with the web site.Hold on here,let me check for ya................................Yep-that is what it is for.LOL.
