Check engine light on for oil change?

So I have a 2009 JK Sahara and I start the car and it says "Change Oil" when I start it like it always does when it needs an oil change. But the check engine light is staying on and I don't remember it doing this before when I needed an oil change. Is it on because I need an oil change or is it something else?

No. Check engine lights do not illuminate because of maintenance. Pull the code and report back.

I think many auto parts stores will pull the code for you. Or buy an ODB II code reader, probably fairly cheap these days.

They won't do it in California, but I think anywhere else you can just go to an Autozone or other parts store and they'll pull the codes for free.

Instead of a dedicated OBDII reader (still surprisingly expensive) you can buy the torque app for an Android device ($5 or so, for tablet or phone) and buy a bluetooth OBDII transmitter for about $15 on Amazon. You can check and clear codes and gain access to a lot of powertrain data.

So your having trouble with your 2009 JK Sahara?
Or your car?
If your having problems with your Car, I would reccomend going and finding a forum for the make/model of your car and asking them.
If it's with your Jeep, then you can post here

The "change oil" message has nothing to do with the "check engine" light. Try this to see if there are any codes.

1. To check your Jeep JK Wrangler’s DTC codes, simply insert your key into the ignition, turn it to the ‘ON’ position but do not start the engine. Then, push the key into the ignition cylinder and while holding it in, turn it to the ‘OFF’ position and then back to the ‘ON’ position (3) times straight making sure to end with it in the ‘ON’ position. It is important to keep pushing in on the key to prevent it from catching at the different positions along the way.
2. If you do step #1 correctly, all your dash lights will illuminate and your odometer will show up as a series of (6) dashes. If your Jeep JK Wrangler has any logged in any DTC’s, they will be displayed soon after the dashes appear. Write down the DTC(s) and check it/them against the list to find out what they mean.
3. If your Jeep JK Wrangler has not logged in any DTC’s, the dashes on your odometer will be followed by the message ‘-done-’. Turn your key to the ‘OFF’ position and you will in fact be done.

First do this and re-set the oil change indicator.

To reset the oil change indicator system (after
performing the scheduled maintenance), refer to the
following procedure:
1. Turn the ignition switch to the ON position (Do not
start the engine).
2. Fully depress the accelerator pedal slowly three
times within 10 seconds.
3. Turn the ignition switch to the OFF/LOCK position.
NOTE: If the indicator message illuminates when you
start the vehicle, the oil change indicator system did not
reset. If necessary repeat this procedure.

I have a 2008 Jk Rubi, and the check engine light came on this morning. I went through the process of checking the codes but no code number appears. I see dashes for a moment and then it reads "Done". Any thoughts??

I've read that certain fault codes will not show when you do the key ON-OFF procedure. Places like Autozone and O'Reilly Auto Parts will do a free code check with their handheld scanner.

Wow, that doesn't sound good at all. I wonder why a particular code wouldn't appear. I'll take it and have the code checked today. Thanks.

Just went though this with my 2014. Couldn't get a code using the key on/off trick. Went to Autozone and they read the code for me. For me it was a code p0520, oil pressure switch, which was replaced at the dealership under warranty.

What's the fault code? Autozone or O'Reilly's will scan it for free.

Just had same code pop up today on my 2014. Guess this means a trip back to the dealer.

I also had a p06de. Did you have both? Or just the one?

ABS and Airbag codes will not show unless you have a more expensive reader that will read these codes.

The OBD-II engine codes should all be readable.

O'Reilly won't pull your codes here in California. I think it is somehow not legal for a parts store to do it - someone motivated to sell you car parts.

In my neck of the woods, the AutoZone folks will read the codes but are not supposed to clear codes. Some will let you push the button to clear, some will not. My theory is real codes will reset quick enough. My TJ had that theory validated a couple of times for ignition misfires (worn plugs). Anything under warranty goes to the dealer ASAP.
