Are you sure it isn't P2146? If it is P2146 it is Injector-group A, supply Voltage-open circuit. Possible causes-Wiring, engine control (EC) relay, injector.

What do these codes mean: P 2146 P 0336 P 0251 P 0191 p 0299 P 020 p 0073


if you just need to know, then google is your friend. If your vehicle has all of these codes then they need to be erased and see which come back. I've seen this many codes of this nature only when I've disconnected all of these items and turned on the ignition and the computer didn't see them all so it set a bunch of codes like this. Has your installation been damaged? Have you recently disconnected all of your sensors?

How do you reset the security light on a 2005 chevy cobalt?


There is no reset , if security light is lit there is a problem with the anti-theft system .Should have it checked for DTC'S - diagnostic trouble codes . Could have 8 different B - codes
DTC B0685 DTC B2955 DTC B2960 DTC B3031 DTC B3033 DTC P1626 DTC P1630 DTC P1631
You would need a professional type scan tool to read these type codes , not an OBD 2 code reader .
