OBD / OBD II

[bunkercowboy]

This morning noticed at some point the OBD sensor came on. Not flashing, car seems to be running as normal. I did check gas cap, seems fine. Have started car one or two more times today and conducted some test in the manual, light still on. I do recall my 2006 Jeep doing same but in 2-3 days light went off.

something I should concern myself with or see if it magically goes away in 2-3 days. The car will probably get parked tonight and not move for ? 1.5-2 weeks.

I would want to know the cause. Get a low cost code reader...or, go to AutoZone and ask them to read it for you.

+1, go to autozone and get the code

 

[bunkercowboy]

humm, good idea. I just called Autozone, will run by there and get back to ya'll.

it showed definition EVAP/ small leak / no flow condition

Prob cause?
Defective or loose fuel cap - checked it, seems fine
EVAP canister or hose cracked - not connected - not seeing any hoses off?
pure or vent solenoid defective ?
Vaccum leak at engine - autozone guy checked a few, saw nothing

Car seems to run fine?

Pretty common codes on cars in general. I'd clear it and watch.

Swap the fuel cap and make sure the seating surfaces are clean. I agree w/ Steve-Indy. Clear it and see if it comes back. Also, sometimes a purge valve leak only occurs in cold weather at first.... Other sources are: gas cap, fuel lines, vac. lines, as you know.

If it returns the system needs to be tested properly by a service tech. with the right tools. There are timed tests preformed by the cars computer, measuring vacuum decay etc... Small evap leaks can be a PIA!

to clear it i need to buy my own code reader i guess? The guy at autozone said he couldn't clear it

 

[bunkercowboy]

How about this one? IT would clear it right?
