Hi i own a 2006 impala ss v8 has 70's klms on it . for the first time my engine light came on since ive bought it at the end of 2005 orginal owner i am . i went out and bought an obo coder and it came up with these three codes - P0443 -evaporative emission system purge control system valve circuit.
the second one was P0689 emc/pcm power relay sense circuit low.
and the last one was P1682- ignition swicth circuit 2.
now im not an mech but i still dont understand any of this i thought it would tell me something like your throttle body needs replacement but it turned out alil hard to understand i found this site and im looking for help on what these codes mean so i could repair the car.. im hoping somebody could help me understand what needs repaired and fixed so i could keep my car in good shape.

Do you have access to an enhanced scan tool that can get into the manufacture's side of the PCM?

If not, your going to have to take it to a shop, so they can look at the freeze frame records to see what the engine was doing when the P0689 and P1682 showed up. If they showed up when you were cranking the engine, you should have the battery tested. A weak battery can cause those codes to set. Usually if those code set while the engine is running, the ETC (electronic throttle control system) will be limited and the engine will run like crap because the PCM will also cut injectors off randomly.

The P0443 can be tested using a functionality test of the scan tool that can enable the purge valve solenoid. If you don't hear the solenoid clicking when the scan tool enables the valve, you need to check the electrical circuits using a DVOM or test lamp to be sure the PCM is turning it on. You also need the scan tool to monitor the desired and actual command percentage (duty cycle) when commanding the valve to see if they match.

I would clear them and see what returns, I imagine the last 2 codes were probably history, or you'd be having a few more problems
