I got hit with one (a failure) this past weekend totally out of left field with no forewarning at all till it died and left me on the side of the road wondering what the heck happened!
This is my story, luckily it has a happy ending.
Was driving home from work and CRD put me on the side of the road for a small spell. (*Very first time*) Going down the road ~40 mph and motor just died completely, no warnings at all. Coasted over to the side of the road, stopped, cycled key off to on several times and then tried to restart with no luck. I had NO DTC's (no check engine light)! Fuel pressure was holding ~14 psig (I have a gauge) so I got out, opened the hood and tried to pump up fuel head, it was already tight and very hard.
Fuel pressure was not the issue! I tried cycling the key to off and back to start several more times to see if it would make it start, no luck. Luckily I had my trusty code reader with me, so I plugged it in and it showed NO DTC’s set???? What the heck is going on here??? So, I told it to reset codes anyway just for the heck of it and walaa, then tried to start it and it cranked right up!!!! Drove it home and it ran like always…
On the way to work early the next morning when it was about half way through the warm up cycle to normal, it skipped a couple of times real quick (kinda bucked or hiccuped like) but did not stop running. FINELY IT SET A DTC on the second hiccup!!! a P0339
Drove it on to work and it never missed another lick.. Of course, when I got to work, I looked up the P0399 DTC on line.
“P0339 - Crankshaft Position Sensor Circuit Intermittent”
So I looked up a crankshaft sensor at AutoZone and they listed one for the CRD Jeep, I called my local AutoZone and gave them the part number and they informed me they would have to order it from who knows where and it would take several days to get it and I told them forget it…
I then called NAPA and he told me he could have one here by 2 pm of the same day, so I ordered it.
Got it and it was made in Germany, hopefully a quality OEM product?
Changed out the sensor the next day! Not a real bad job from underneath, just had to remove the big skid plate under the transmission and transfer case to get at it. 10mm socket to remove heat shied and CPS bracket & a 5mm allen to remove the sensor. It popped right out after I twisted it around a little bit and then pulled on it...
Runs like a sewing maching now and hopefully this saga is behind me???
Just very glad it happened while I was close to home and not on some road trip!!!!!!!!
