My MIL was on and I had a code that indicated that I needed to replace my Oil Pressure Sensor. I went to a non dealership mechanic who would allow me buy my own parts, because I also needed the L & R front wheel bearing hub assembly replaced; I refused to pay for the parts via the repair shop price. After getting my vehicle back, not only is the MIL still on, now my Oil Pressure Lamp is on.

I want to take my Jeep to a friend, whom I trust can trouble shoot and fix the problem; but, he lives 21 miles away. I am afraid to drive that far in the event it causes damage to my engine. I have limited my driving to only when I absolutely have to, at most I drive 2-5 miles a week, I am afraid driving short distances with these lights on will damage my engine.

I wonder if the guy who replaced the oil pressure unit damaged it when he did the repair? I thought to buy a new one and was going to go to AutoZone so I don't have to wait and pay a little as possible using my reward points. Auto Zone caused more confusion, they are asking is this with a gauge or with a light; I told them I have a light indicator, and they said I need the unit with only one thingy in stead of 3, but when I search for the part based on my VIN I am shown 05149062AB. The part I previously bought was 05149062AA. Is there a difference between Jeep parts 05149062AA & 05149062AB?

Any suggestions?

This might help https://www.jeepcommander.com/forums/9-problems-dealer-service/73563-oil-pressure-sender-part-number.html#post534811. If the engine does not get enough oil going to the bearings even 21 miles will kill it. I would not drive it unless I was sure that the sensor that was bad. The problem may be a loose/unhooked connector, if you can, double check that it is connected tight. Just to cover the basics, check that you have enough oil in the engine.

Thanks for the the link. :smile2: I did check the oil it has the required amount. The only symptoms I have noticed is there is oil all over the place on the under carriage of my Jeep. I have inspected the ground after parking, no obvious oil on the ground. I have only smelled oil, the smell lasting a few seconds, twice. I also happened across a youtube video discussing the tools needed to install a new Oil Pressure sender; it was suggested that not having the correct tool can break the Pressure sender, creating a leak. The video showed a under carriage that looked as if it could have been mine, and the person in the video claimed that a broken oil pressure sender made the mess.

I wouldn't be surprised if the mechanic was careless, when I got my Jeep back I was missing one lug nut; and, he put my lug nuts on so tight they were stripped.

Well that escalated quickly. I know it's a hard pill to swallow if this is your daily driver, but I would not be doing any driving until it gets a good look over. I take it this is the original engine in the 2006?
