Hey All,
I have a 2008 jk. 127000 mi. Today my engine light came on and next to it a light came on that said “oil” ?
My oil is fresh and is up to proper level.
The book tells me that a “change oil” light will come on if the Jeep feels an oil change is needed.
My light just says “oil” only. Not “change oil” ?
My running temp is good.
Could the “oil” light really mean “change oil” ???
Or what else could it be ?
Thanks
Tom
 
Did you turn the ignition key on and press the accelerator pedal three times within 10sec to clear the oil light? My check engine light has been on for ten years( it is a Jeep) I do not bother with the code reader unless my ride is off. And I only panic if the MIL light goes off now. LOL

After I changed my oil change I reset the oil change message and then after about 100 miles the oil change message comes on all the time. It's just another one of those Jeep things.

I installed a real oil pressure gauge on my Jeep so that I know what my oil pressure is all the time.

This thread makes me think my sensor is broke…never reset after oil changes and it never comes on. :unsure:

Downstream driver side. Check your live data to see if it’s fluctuating properly on voltage. If it’s not, and you’re lucky, maybe your sensor just nutted out. Then it’s an easy fix. Good luck brother 🍺🍺
 
Not usually. Run the Jeep a little to warm the exhaust up some. I’ve had some turn right out before and I have had to put a small map torch on some to break loose. Make sure that your replacement has anti-seize on it.

Are the downstream and up stream sensors specific to thier location ?

You need to buy this Brand they are OEM, if you look them up I think the 2 front ones are different PN's and the rears are the same PN's.

U need the NTK 23159. Keep in mind that the downstream sensors only read the efficiency of your cats. The upstream controls the fuel to air ratio. Your ECU has a set parameters for the sensors. If u have a cat that is just starting to nut out even slightly out of that parameter it will throw that 158 code. Never hurts to change that sensor. A faulty injector will throw it also. If your Jeep is running fine and your fuel mileage is steady a failing cat can be fine for quite a long time. Keep in mind if you have no emissions testing in your state u can always get a set of O2 foolers online from Walmart and they will definitely shut that annoying CEL light off. I use them as well as a lot of other jeepers. Be happy to help u any way I can🍺🍺

Hey Tom, did you already do these things? I'm having a hard time reading replies so pardon me if this is a repeat:
To reset the change oil light on a 2008 Jeep Wrangler, follow these steps:

  1. Turn the ignition to the "ON" position without starting the engine. This is usually the second position in the ignition sequence.
  2. Press the gas pedal three times. Fully depress the accelerator pedal slowly three times within 10 seconds.
  3. Turn the ignition to the "OFF" position. Once you've pressed the gas pedal three times, turn the ignition off completely.
  4. Start the engine. Turn the ignition back on and start the engine to check if the oil change light has been reset.
If the light is still on, you may need to repeat the process. Make sure you are pressing the accelerator pedal fully and within the required time frame. If it still doesn't reset, there might be an issue with the vehicle's computer system, and you may need to consult a mechanic.

BigAL07, thanks for the info. After I replace the sensor, do I have to reset the engine light some how, or will it go off automatically?
 
Google up wrangler ecm reset and do that. If u leave it on it takes around 3 cold starts to shut it off. Must be cold starts First start of the day. Either way if it comes back on it could be another issue. Good luck. Let us know🍺🍺

How to Reset the ECU on a Jeep Wrangler JK

While there are folks that swear resetting your ECU does absolutely nothing, it's a common practice among automotive enthusiasts. The ECU (Electronic Control Module) "learns" your driving style and the parts in your ride by storing information in its memory, information that it gathers using a...

I'm not certain about 2008s. My vehicle, which is a 2016, has two indicators. One warns about low pressure, a small oil-can icon dripping oil. The message to change the oil happens when the motor is started and it makes a "ding" sound and displays a message. You might want to search for a copy of the manual if you don't have one.
