bear with me, this is a long one - I want to describe what lead up to the issue I'm having.
our Liberty has had a miss to it and a lack of power on acceleration since we bought it about 6 months ago , the engine would develop a nasty miss when you gave it any throttle, but it never threw any codes, just had a bad miss, so a few weeks ago I changed out the crank position and cam timing sensors. (I bought those sensors off ebay, dirt cheap, something like 20 bucks each) it ran worse when I put those new sensors in it, the miss got terrible to the point that it wouldn't want to accelerate at all, it would idle fine, but wouldn't accelerate, it would just die out, this time the check engine light came on but at that moment I did't have my code reader with me to see what the code was it was throwing (more on that later)
at that point, I thought that maybe I had bought a bad cam timing sensor, so I put the old one back in it, reset the computer, and it ran fine, except for a slight miss that I felt like was probably the spark plugs.
our Liberty has been running fine for the past few weeks except for that intermittent miss that I associated with the spark plugs, so about 2 weeks ago, I put new plugs in it and the miss went away and it's been running fine.
ok, up to this point, I have new plugs, new crank sensor (I bought off ebay dirt cheap) but I'm still using the old cam position sensor.
the weather started getting hot here in Oregon over the weekend and Saturday while we were out with our Liberty that check engine light came on, (again I don't have my code reader with me) the car died, got it started again, ran like crap, I nursed it off the highway into a parking lot, disconnected the battery, reset the computer (which clears the codes), then fired it up and it ran fine the rest of the 20 mile trip home, drove it Sunday with no issues, (now I have the code reader with me, but now it's running fine, go figure) my wife took it to work (30 miles away) on Monday and it did fine, got off work when the weather was way hot, and it did it again, she pulled over and reset the computer, did this 3 times trying to get it home, the third time she couldn't get the check engine light off, so she nursed it up someones driveway and (with their permission) left it there.
so at this point, I'm thinking, that the only new part I have in the car is that crank position sensor and it didn't start running this bad until after I put that sensor in it - (remember, the cam timing sensor up to this point is still the original) so in my head I'm thinking maybe that dirt cheap sensor I bought off ebay was a bad idea ....
I showed up at the Jeep with my code reader and checked it - it's spitting out P0335 .... the crank position sensor.
seems like it's an intermittent problem because you can reset the computer and it will run fine for a little bit, then boom! ...it trips the check engine light again and everything goes to pot.
as of this point, the car has been sitting for 24 hours with the battery disconnected, so I'm going to hook it back up, hope the code is gone, and see if I can nurse it that last mile to my house.
if I can get it home, I am then going to go to the dealer and buy a crank sensor (which I'm showing two parts numbers for with two different prices, one 80 bucks and the other one is 45 bucks) both of they say they are for my 2005 Liberty with the 2.4L powertech engine.
so which one is it? 056041552AD or 05269873AD?
I'll keep you posted - this is driving me nuts.
