Jeep Patriot 2009 check engine light help plz

[SoccerDude]

Hey gents

I was wondering if anyone could help me out.

Yesterday, on my jeep patriot i removed a plastic cover to get to the battery, so i could boost my honda civic who's battery died.

I installed the plastic cover back in it's place. Yet this morning, i got a check engine light on my patriot. I did the 5 seconds on off trick. On my odometer, it wrote DONE.

So what do i do to make the check engine light go away? or is it possible that something is wrong even though the odometer says DONE.

thanks in advance

Try going to one of the local auto parts stores that'll read codes for free. There's not much around the battery cover/air intake that could cause a check engine light. See if you can get the code then report back.

Could be coincidental,
Or the jump could have just caused a spike/surge in voltage somewhere.
If someplace reads codes for free use that,
If your due for an oil change soon, wait and ask them to check it when getting the oil change.
Did disconnect the battery at all? As low voltage from disconnecting the battery can also throw a code

Agreed! I would suggest NEVER using your Patriot to jump another vehicle as the risk of damage to your car/computer is just too great! For about $40, you can get a rechargeable start box (battery in a box) from Harbor Freight that'll handle jumps.

Thank you for the help guys
Funniest thing, the check engine light suddenly disappeared after driving for about an hour. I turned off the car at the gas station, turned it back on and it just suddenly disappeared. Don't know if it will come back or not. Sure hope not.

Thank again gents

I've probably jumped close to 30 vehicles with my Patriot so far, and the one guy I helped hooked his end up backwards. Them cables got hot in a hurry!

OBDII vehicles will reset themselves for most codes if the fault goes away. There is still a code stored in memory though, so you could still get it retrieved. But if it stays off...

Dealer will charge around $80 for the scan, even if during other mait.

My light came on twice, first time the engine blew, second time not long after that, took it in right away and they fixed under warranty. But, if the repair was not warranty they would have charged for the scan.

One of my favorite Amazon purchases of all time....(I got for $15..now it's a tad more)

I like to scan my codes right away just in case....


It just tells ya the code # and you have to look it up online. Also is capable of deleting the code and the check engine light.
