   okay what is p0017,pood4, and p0018

2. wayoflife December 7th, 2007 10:52 am

   From what I can tell, both P0017 and P0018 are the same as P0016 - Crankshaft Position - Camshaft Position Correlation, except that 17 refers to “Bank 1 Sensor B” and 18 refers to “Bank 2 Sensor A”. Unfortunately, I do not know what P00D4 is. Sorry.

   Thanks for posting this! Hopefully I won’t need it for some time, but I’m sure this will definately be useful in the future

   If you take things literal, there is no “OFF” on the ignition switch. You have “LOCK”, “ACC”, “ON”, and “START”. Follow the instructions above, but cycle quickly between ACC and ON. Works for me every time.

   thanks for your help eddie

   OK I have tried this SEVERAL times and it does not work ! WTF ??
   Even when the key is pressed into the ignition I can still feel the detent positions between off (lock) and on….the key does not stop at the detents, it’s just that I can feel that they are there. Is some thing wrong with my ignition switch? Does this work on all JK’s? I have a 2007 2 door Rubicon 6 speed that I purchased in Feb-07. got any tips??

   Thanks, Paul

7. wayoflife December 13th, 2007 10:05 pm

   Hey Paul, feeling the positions is normal. Did you make sure to start from the on position (last spot just before your starter begins to crank) and did you make sure to do this rapidly? Also, did you try what AZJeeper suggested?

   Thanks SO much for this. I have had check engine lights come on no less than 10 times .._ this is quite annoying for a JEEP 6000 miles on it. CHECK ENGINE… what in the H_E Double_Toothpicks is that supposed to mean? This should be i the owners manual.

   Thanks Again. Ev

    Any way to clear out codes?

11. Ron February 2nd, 2008 2:49 am

    How do I reset the codes?

12. wayoflife February 2nd, 2008 12:29 pm

    To reset your codes, you can disconnect your negative battery lead for about 5-10 min. When you hook it back up, they will be gone and your computer will start learning again from there. Or, if you have something like a Hypertech Max Energy Power Programmer or ACCU-Pro, they can clear out your codes as well.

19. Snippy August 20th, 2008 4:28 pm

    I had a P0018 code, though all 5 of my tires are at 26psi (35″) and yet none of the low pressure DTC’s were shown on my Hypertech even though the TPMS dash light stays on every time I start the vehicle.

20. Khaiwi August 26th, 2008 4:51 am

    Hi, I connected the Hypertech power programmer and got U0154 LOST COMMUNICATION WITH OCCUPANT CLASSIFICATION MODULE …… wonder what should this mean????

    I have code …… and after 2 sec No bus -wonder what should this mean????

23. Redrock February 26th, 2009 11:55 pm

    I got 3500 miles on my 2008 Wrangler Unlimited X and it kept telling me to change the oil. I finally got a check engine light and changed the oil after that. Went through this procedure to find out why the check engine light came on. It seemed to work great and all it says is “change oil”…no code. Is that normal?

24. Curious March 2nd, 2009 2:35 pm

    I have several codes not on the list. All of them have the 3rd digit as ‘0′ which isn’t on the lists above. They are all ‘P00xx’. Is there a portion of the DTC list not printed here?

25. wayoflife March 2nd, 2009 3:20 pm

    sometimes if you have a reoccuring trouble code, the last digits indicate how many times the problem has been experienced.

26. brian russell March 6th, 2009 11:11 am

    i have a hypertech max energy power programer and the dtc code that can up was P0000 can you tell me what this means thxs

27. Tim Schroeder March 14th, 2009 7:22 pm

28. Tim Schroeder March 14th, 2009 7:26 pm

    LOST COMMUNICATION WITH CLUSTER/CCN - u0155 -2005 jeep rubicon - 6 cyl - 6 speed

29. J stone April 6th, 2009 3:52 pm

    P0562 System Voltage Low does this mean that I need to change the batteries on a 2007 4 door wrangler?

30. ken May 21st, 2009 12:15 am

    this is great news.

31. Jr July 29th, 2009 12:07 am

32. Isaac August 8th, 2009 1:18 pm

    Has anyone in this forum ever get codes P0203 and P0303 at the same time and how did you fix the problem? Thanks in advance.

33. gator August 11th, 2009 11:17 pm

    azjeeper’s suggestion worked for me.

    Start in the ON position. Then cycle back to ACC and up to ON three times fast (within 2 seconds or so), ending in the ON position.

    I’m having intermittent starter issues. They replaced the ECM (I think) a while back when it wouldn’t start at all, and now have ordered a WCM.

34. mark johnson November 2nd, 2009 1:40 am

    I had a hot oil warning after running in soft sand, I’m assuming it meant trans as the water was normal and that a extra cooler will keeping it from happening. again

35. leticia November 12th, 2009 1:11 am

    I just bought a 2009 wrangler and as soon as I got home a “hot oil” indicator light came on? I cannot find this issue in the manual…please help!!

36. wayoflife November 12th, 2009 1:26 am

    typically comes on when climbing a long hill and your tranny has to keep shifting. try shifting to 2nd or 1st next time.

37. Paul December 14th, 2009 12:13 am

    What if I get the —done— message but the CHECK ENGINE light remains on?? Thanks…

38. wayoflife December 14th, 2009 12:45 am

    disconnect your battery for about 15min. that should clear it.

39. cory December 18th, 2009 8:11 pm

    I got the p2504 code, which is charging system output high, I checked the output to the battery and it was sitting right below 14.4 volts which is right where it should be. Just wondering if i could get a little more info on this issue if at all possible. Thank you

40. greg January 17th, 2010 4:41 pm

    Hi Everyone,
    I have a problem with my instrument cluster. For no apparent reason, the cluster had no power to it one morning when I started up my 07 JK. I disconnected the neg terminal on the battery and waited approximately 10 minutes. Reconnected. Dome light came on, instrument cluster had power. As soon as the dome light timed out though, instrument cluster lost power again. Checked schematics and am down to the “immoblizer” circuit. Is this something that I have to take to the dealer to get checked out on thier diagnostics?

41. SmilinVamp March 31st, 2010 3:28 pm

    HOTOIL - part of a recall I just had to do. Turns out they’ve discovered that the Auto Transmission isn’t really good enough for the Jeep (Surprise). So instead of giving everyone a nice new Tranny cooler… they just added a fancy light to tell you the Tranny is hot.

    They include an addendum to the owners manual - when the HOTOIL indicator lights, pull over and idle in neutral until the light goes out. Then carry on… nice of them huh?? (I ain’t kiddin’)

42. tina April 22nd, 2010 11:03 am

    Hi guys I need your help- My baby is pulling the code P0016 crankshaft/camshaft timing misalignment (2005 Wrangler Sport) and we have replaced both the crankshaft and camshaft sensors ($70.00 later) and it continues to pull the same code. I have done the research and have found the there was a service bulletin issued (E05 or NHTSA Item# 10013784, Oil Pump drive gear may wear out prematurely and cause engine failure due to loss of oil pressure) but I have not have a problem with losing oil pressure. Can anyone tell me if an Oil Pump Drive Gear is the same as an Oil Pump. I am thinking that it is not and that the Oil Pump Drive Gear is probably located somewhere around the camshaft but I am not sure. Can someone please tell where it is located and how hard to replace on my own without having to take it to a shop. Thanks so much in advance for all of your help and experise

43. Jeep Tech May 14th, 2010 8:19 am

    The same gear that drives the oil pump also drives the Distributor/Cam sensor…

44. Dave May 18th, 2010 12:37 pm

    I’ve had the engine light come on about 4 times lately. Drive it for awhile and it goes of. Drive it again a couple times and it comes on again. Decided to check code this time. it is:
    P0057 O2 SENSOR 2/2 HEATER CIRCUIT LOW

    And this means…???

45. Briou July 10th, 2010 10:12 pm

    So both my battery and my alternator both went out on my 07 jeep jk…I thought? I replaced both of them and now I am getting all kinds of electrical trouble. When I am driving my cluster goes nuts…speedo and tach both start bouncing and every possible engine light comes on. I checked this with my Hypertech programmer and I got the following code, some of them are listed here but others are not. P0000, U0001, P30D1, P1330, U1403, B30D1, P0CB0, U110E. Please I need some help. Thanks

46. wayoflife July 11th, 2010 11:47 am

48. wayoflife July 25th, 2010 1:27 am

    sounds like you might have a bad wiring harness. there was a recall on this a while back if i remember correctly.

49. Scott August 8th, 2010 6:59 pm

    Hello. I just bought a 2001 Jeep and after 200 miles engine light is flashing. Diagnosed the following things: P0202, P0302, P1281. Is this reason for concern? What do I need to do? Do I need to bring it in for servicing already? Thanks!

50. HIDavid August 18th, 2010 1:44 am

    Hello, our 2006 Wrangler Sport will turn over but not start. The Fault code reads P0522, which is the Oil Pressure Sensor reading low. Suspecting the sensor might be bad, I replaced it, but the engine will still not start. Same fault code reads out. Am I missing something or am I really looking at a failed oil pump or failed oil pump drive? Should something be reset to allow the engine to start?

51. jeff August 29th, 2010 12:07 am

    I got some DTC’s that read P0000 and U3001, should I be concerned, thanks.
