Hi rnc. It looks like it might be a low voltage warning code since you just changed the battery. It could be one of many related things but in your case I would first check that my battery terminals are tight; also the battery may have been installed before it was fully charged. I do not know if the check light will automatically go off when the battery is fully charged if that is the case. I'm quite sure others will have more insight and details about this after which I would probably refer to a Jeep dealer. Good luck.

 

If you know the battery is good, and it should be if it is new, then I would have the code cleared and see if the CEL comes on again. It probably won't. Let us know if it comes on again though.

 

The battery is new (is not MOPAR) . ¿how can clear the code?

 

You can do it with a handheld scanner or autozone can usually do it.

 

I do not know what happened, but the light turn off by itself. Everything is ok.

thanks everybody.

Crazy Jeep.

 

Could be, like has been said, that the new battery was not fully charged when installed.

 

Maybe they disconnected the positive cable first? With OBD II, most error codes will turn off by themselves if the fault is not detected again for so many key-on-off cycles.

 

Hey Guys,

So I am doing some research and I just purchased an 07 Pat. It had a CEL on, and the owner told me that it came on about 1 year ago, but the truck runs great and no problems. I had an OBDII scanner and pulled a 1607 code as well. Looking into it, I saw this thread and checked out the battery... sure enough the sticker said 1/14 on it...implying that it was purchased and installed January last year.

I cleared the CEL, and drove it around 100 miles. All checked out, and the truck ran great. The next day, I started the truck. (cold start... cold day) and the CEL came back on.

Ive had the truck for about 3 weeks now, and have probably put 1200 miles on it, but the CEL wont clear itself.

Any thoughts guys?

 

This is why I encourage everyone to invest $90 in a factory service manual CD. It will pay for itself in one use.

PM me if you want more info on the P1607 code.

 

Where do you get one of the electronic service manual?

 

chethro,

I bought mine out of Canada from this place: http://servicerepairmanuals.com/store/search_result.php ....Authorized Mopar manual distributor.

Prices range from $66 for the 2007 up to $90 for the 2014+.

This is the same disc sold in the US for about $135 at Mopar's Tech. Authority: https://www.techauthority.com/en-US...engine=2.4L+4+CYL+DOHC+16V+DUAL+V.V.T.&producttype=Service+Manuals&ptCatId=3083

My only criticism is that it should have a better searchable index to aid in searching for topics. Sometimes I have to dig through layers to find something specific, i.e. spark plug number.

 

Thanks, does it include wiring diagrams?

 

I see no wiring diagrams, but troubleshooting help. Nice!

 

Yes, it states no traditional wiring diagrams, but "wiring info" when you go through the diagnostics codes. Probably not much help.

I don't know for fact, but my Mopar dealer mechanic friend said his CD manuals cost in the hundreds of dollars ($300+/-) and I am thinking his version has everything: wiring diagrams, maybe part numbers, etc.. Just a hunch. There are $300 versions on Ebay, but their description is weak.

 

We don't use CD manuals. I can access service info via dealerconnect.com from any computer.

 

So have a question for everyone. My baby sitter went to jump her car hooked up cables wrong. Its a 2016 jeep patriot 2.0 engine. Ran a diagnostic on it is reading nothing. It will crank is sending fuel to injectors. Put a new crank shaft sensor in it replaces the pcm checked fuses and relays. There is no sparks coming out of thr coil packs. Running out of ideals of what it can be. I do know when starter cranks it does keep cranking when you let go of the key. Anyone have any ideals of why its not sending a spark to the coil packs?

 

I have a 2010 jeep patriot and the code is p1607, I'm unclear on it and I was told it has a new battery, should I be concerned

 

This is what I found:

------------------------
What are the Possible Causes of the DTC P1607 Jeep?

NOTE: The causes shown may not be a complete list of all potential problems, and it is possible that there may be other causes.

• Low battery voltage
• Faulty Alternator
• Engine cooling conditions that may set the code
• Engine coolant level
• Faulty Powertrain Control Module (PCM)

What Does the P1607 Jeep Code Mean?

The Powertrain Control Module (PCM) compares actual shutdown time to a calculated shutdown time value. The calculated shut down time value is based on the amount the ECT should drop after a completely warmed up engine is shut down for a minimum of 8 hours. If the difference between actual shutdown time and the calculated shut down time is greater than a maximum value, a one trip failure will set. The shutdown time is measured again after 1 hour of ignition off time following the next engine warm up cycle. The PCM compares the shutdown time to a calculated value. If the difference is greater than a maximum value, the MIL is illuminated and the P1607 code will set.
--------------------------
The first thing I would do would be to check all the the cable connections on both ends of the battery cables to ensure that they're clean and tight. Tighten as necessary. Then head to your local auto parts store the get the battery and alternator tested. They'll do that for free. And just so you know, a new battery does not equal a good battery, they can be bad straight from the factory.
