Okay guys its smog time and im in california my car is throwin a few codes ill list em here so maybe you guys can help me i gotta get this this smogged and reg.

12 - Direct battery input to pcm disc in last 50 cycles. - I haven't disconnected anything.
31 - Evap purge flow monitor fail or evap solenoid circuit.
42 - Fuel pump relay or sumthin else i can't remember.

Is it possible to pass smog with these and also guys have any idea on what ima have to do to fix these?

Thanks in advance,
Tim.

 

42 could be any of these things...

42
P1282 Fuel Pump Relay Control Circuit
P1388 ASD Relay Control Circuit
P1389 No ASD Relay Output Voltage At PCM
P0460 Fuel Level Sending Unit & Circuit, No Change Over Miles
P0462 Fuel Level Sending Unit Voltage Out Of Limits, Too Low
P0463 Fuel Level Sending Unit Voltage Out Of Limits, Too High

so best bet would be to got to napa and barrow there obd2 tester to get the exact code...

how ever you would not be able to pass if you have the evap code... let alone the fuel code...

 

Thats what i was afraid of...
How would i go about fixin that evap

 

you need to trace the vac tube off the tb to the carcoal canister under the front bumper cover... then trace the lines back to the tank look for cracks and splits or rotting... then check the vacl lines around the evap purge sylinoid mounted on the passenger side motor mount... check the wires on the plug... thats about it... its not that complicated of a system...

as far as the 42 code your going to need to find out the exact code by getting a obd2 reader on it... then let us know and we can walk you threw that too...
