    Here is some info on cyl 3:
    http://www.obd-codes.com/p0303, as for 02s and egr I need the specific P code to give you more info and if you smell rotten eggs in the exhaust then you have a problem with the cat. Sorry but I would need to be there to check the reader. Pep Boys and Auto Zone will check codes for free.

    With regard to the reader, check for a blown fuse, they tell me that it may be on the circuit with the cigar lighter.

    07 Ram 1500 SLT 4X2 4.7 545RFE -

    Today I drove to the coffee shop two minutes down the road from work. I was in the coffee shop for like 3 minutes, and when I got back into my truck and tried to start it nothing happened. My truck has Tip-Start, and no matter what I tried to do, it wouldn't do anything... no crank at all. The yellow check engine light was illuminated, so I opened up the hood and checked all the fluid levels. This is the first time the truck has given me any trouble at barely 300 miles away from it's first 50K. As soon as I got back into the truck and tipped the ignition switch, it started right up as it normally does.

    Is it possible the relay that actually powers the starter is going to belly up and it's blowing a code because the ecm isn't sensing power when I tip the ignition switch to start the truck?

    Thanks!

    This happened to me a few times too on my 07. It simply wouldnt work for some reason? Started working again though and not sure what fixed it? Try disconnecting the battery for 10 minutes and re hook it up, that might reset the computer.

    I have a 2007 Dodge 2500 5.9lt diesel. Recently the ABS and Brake light come on and off intermittently. What is this caused from and can it be reset. When cycling the ignition no error code is displayed. :cry:

    If you also notice some fluctuation in your speedometer when the lights come on, it's likely your speed sensor (located on the rear differential). Usually a quick fix.

    I haven't noticed a fluctuation in the speedo. I'll have to keep on eye on it and see if does. Any idea what else it migh be. Thanks for the replay.

    If you're not noticing any brake issues and the brake fluid looks good, the sensor is the most likely culprit.

  • I have a Ram 1500 with a 4.7, it is and always has run very good. I have been very satisfied with my truck which I don't plan on parting with anytime soon. Well I got in it the other day and the check engine light came on. I took it to my wife uncle who scanned it and told me he had never seen this code before, it read
    601 Internal Control Module Memory Check-Sum Error. any ideas. The truck has about 168,000 miles on the clock.

    This code,means the pcm has gone bad. In some cases the dealer can reflash it and get it working properly but in most cases it will need to be replaced and reprogrammed. http://www.obd-codes.com/p0601

  • Thanks corkscrew, I really appreciate it! Am I talking about a lot of money here?

    The last few months my truck has had a mind of it's own. When I go to started it in the morning it will turn over but not start up. Last week going through a development gate it stalled I put it in neutral and tried to start it after the third attempt it started and I had no trouble until Monday morning would not start after many attempts. That afternoon it started up first try. Wed worked all day until 2:30 that afternoon driving down the highway and the rpms kicked up 10 mph and it shut off. I saw the no bus code for the first time, it did start up approx 10 mins later but shut off again I read that if I replace the pcm that would fix the problem. Does this really work ? Ol' Blue has 325K and drive her 120+ a day 5 days a week. I am extremly impressed the abuse it has taken with only minor repairs. I would really like to keep her as my work truck beings she knows her job !

    Could be a faulty crank sensor. Sometimes they act weird. Auto Zone, O'Reilly, etc can scan it (free) and tell you. bobwinner

    Have a problem with passenger front window on my 2003 Ram. Window works from main control panel on driver side but won't from passenger side. Replaced window switch on passenger side but didn't make any difference on making it work from there. Any ideas?
  • bobwinnerbobwinner Posts: 47
    I can tell you it probably is not the window , motor, track, etc.I have an 2003 Ram 4 door, and quiet often, without warning, I lose the ability to operate any of the three windows from their individual switches, although all operate from my drivers position. I own a repair shop, and have access to other Dodge parts. I have switched each motor, each switch, and the driver main switch. Nothing helped. Then I got a new transmission (yes, the main truck drive transmission) and EVERYTHING worked for 4 months. Now they are inop again. Dodge dealer suggested I open the door and wiggle the wires , but that does not help. Good luck. bobwinner

    I used to own a 2002 4door ram and I had the same problem. All windows would work from the drivers position but sometimes the passenger and rear windows would not work from their individual switches.
    This problem would occur when I used it during a rainy day. Once I pulled up on the lockout switch on the drivers door and reached over to the passengers window switch and the window went half way down and stopped.Another time I wiggled that switch while I pulled up on it and again I reached over to the window on the passengers side and it went down but not up. If I waited a few days all the windows would work normally. Hope this helps in some way.

    I have a 2004 Ram 1500 hemi. While driving the instrument panel goes crazy and air bag light goes on and off. Sometimes I have to crank it a few times to get it started. I checked and got a code of U0155 lost communication with IPC. What could be the problem? What is the solution?
  • KCRamKCRam Mt. Arlington NJPosts: 3,516
    If you're losing communication between the IP and the module, that's usually the initial sign of a failing computer.

  • I have a 2006 dodge ram 1500 with a magnum v8 i just bought. It has 60,000 miles on it. Tonight i started it up and the light for emision controls came on. Any ideas?
  • I had my 2006 dodge ram 1500 tested to find out what the light that came on was about. It came back transmission control module. It lets you drive only in 2nd gear. They told me that was a fail safe mode. to get it to the dealer. any idea on cost and how long that repair takes?
  • I have started getting an engine light indicator, the fuel gauge then drops to empty and the fuel warning light comes on. All of this despite having gas in the tank. The code I get is P0463. Any help to solving this problem would be great. Thanks
  • corkscrewcorkscrew Posts: 254
    Fuel level sending unit, volts too high. Failed tank float sensor or broken wire. Check sending unit connections first.

    Hey all....
    Have a 02 dodge ram 1500 and about a month ago my stereo stopped working but would come on and off periodically but now stopped working all together. Now I know your thinking then there is something wrong with the stereo but there is more. I now have a flashing red light on my dash that was never there before, and unless the truck is turned on my power windows and locks don't work. My check engine light is on and my rear lights stay on for about 30-45 seconds after I shut the truck off. oh and my interior lights won't work unless the truck is on. I am just wondering if might be fuses or wiring problems? Any answers would be greatly appreciated!!!!
  • i have a 2006 dodge 3500 with a diesel engine.i had a code poped up tonight.the code is 11
  • I have 06 cummins and I fired it up the other day and both of these dashlights came on. Any one know what the cause of these lights being on?
  • KCRamKCRam Mt. Arlington NJPosts: 3,516
    That usually means the computer has detected a fault in the ABS system and has disabled it. You still have regular service brakes, but they will now be susceptible to locking in a hard stop.
