Check engine light after oil change
Today I had my oil changed, should have done it myself but I didn't have time so I let my father take it to get it done and one of those quick change places. Well, I get in my jeep and turn it on and the check engine light comes on. I have been looking for about 30 minutes and have no clue what the problem is. Any ideas?

Oil change, I have to turn key to on position (not start) pump gas pedal 10 times and turn the key back to off.- to get oil light to turn off.
Or just disconnect the battery for a few minutes

If you're referring to a code that an obd2 reader would give, no as I didn't get in the jeep until about 8 o'clock and don't own a reader. I was planning on having a diagnostic run tomorrow if I couldn't figure out the issue tonight

It could throw a code for using the wrong oil weight. It should a stored DTC if that's the case and just take it to the dealer to get the right oil and have them clear it.

To check your Jeep JK Wrangler’s DTC codes:
1. 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 logged any DTC’s, they will be displayed soon after the dashes appear. Write down the DTC(s).
3. If your Jeep JK Wrangler has not logged 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.

Here is how to do it without a reader. If you get the DONE message, with no codes, then try a reader, as the self method doesn't show all stored codes.

Ok. Just did that, got "P 0455" and a quick google shows that this is "evap leak monitor large leak detected" and people were saying that means the gas cap isn't on. Which I just checked and it is. Any more ideas?
