93 Intrepid will not start...Please Help - 9/5/2006 10:16:33 PM    ryanp77   Posts: 4 Joined: 9/4/2006 Status: offline Car began running very rough and after shutdown has not started since. Seems to turn over strong when cranking, but no real effort to start. Checked spark on two wires with no spark detected. Ran the OBD codes and I get Codes 13 and 54. I think that code 54 is in reference to the cam sensor but I read elsewhere on the forum that a bad cam sensor will not cause the car to not run altogether. The car has the 3.5 Liter 24 valve motor. Here are my Questions... 1: Is there a way to test the cam Sensor? Will the cam sensor have any visible signs that it has gone bad? (picture of sensor below) 2: With these particular Error codes, is there a quick easy diagnosis (I know, but I have to ask) 3: Where would be the best place to start troubleshooting from this point? Thanks to any help in advance. Not having this car running to get back and forth to work is gettting very old on my wife since she now has to drop off myself at work, my children at school and go to work herself all within 15 minutes every morning..hehe Thumbnail Image Attachment (1) < Message edited by ryanp77 -- 9/5/2006 11:38:01 PM > Post #: 1

Code 13- Indicates a problem with the MAP sensor pneumatic (vacuum) system. Code 54- No camshaft position sensor signal at PCM. Problem with the camshaft position sensor synchronization circuit. I admit I have no clue about what these really mean and how to fix them, but I hope that has been helpful. I'm not very good with "do it yourself" repairs. I'm not educated on the subject of sensor issues; therefore, I'm not very helpful in that area. I think some places like Autozone will do a free diagonis on this stuff or might be able to tell you more. BTW, when was the last time you had your spark plugs and wires done. Earlier this summer, my 3.5L started running very roughly and the check engine light went off (I didn't catch which codes it was giving me). I brought it in for the experts to look at it and they said it needed new spark plugs and wires. That solve it. Since you mentioned that two wires didn't have any detection of spark makes me wonder if they aren't getting old. Also how many miles do you have on this car? Good luck! < Message edited by 97 3.5 Intrepid -- 9/6/2006 12:17:15 AM > _____________________________ College Graduate B.S. in Marketing (in reply to ryanp77) Post #: 2

I am happy for conformation on the codes, the only OBD list I could find on the site seemed to be for a Neon and I wasn't sure if it would be the same. I am with you on the DIY level, most certainly a novice here! I can muddle and poke my way through most things, but it takes a little longer since I have to do alot of research! The car has about 110,000 miles on it, and the plugs and wires were replaced about 6 months before the car stopped running. (in reply to 97 3.5 Intrepid) Post #: 3

If you replaced the plugs and wires 6 months ago, then it probably isn't that. You should have plenty of good miles let at only 110,000 miles once you get this fixed.

If it is the cause of your demise, simply unplug the connector for the map sensor, the computer will set a default value for the "limp home mode" and see if the problem re-occurs. If not, buy a new sensor for about $50 and take about 1 min to install it. It is located on the intake manifold driver side fwd. It is a small square box threaded into the side of the manifold (you can usaly change it by hand) with one ele connector. Good luck (in reply to highline95jl) Post #: 7

RE: 93 Intrepid will not start...Please Help - 12/3/2006 1:42:14 AM    popimp   Posts: 3 Joined: 12/3/2006 Status: offline The engine will not start without a cam reference signal, the ASD relay will shut down spark and fuel to the car within a second if the PCM does not recieve a proper cam input signal. I would recommend leaving the battery unhooked for about a 30 minute period and then reconnecting. After this reset the TCM and PCM according to instructions at www.dodgeintrepid.net (yay more advertising). (in reply to kurts2) Post #: 8

If he recived a defective on then sure, but until he uses a OBD scan tool to reset the code, it will remain in memory for around 30 key cycles (I'm not sure of the #). If the sensor is a good one, it should start right up even with a fault in memory. As for the battery disconect, isn't that to erase the long term correction adjustments? (This can also be reset via the scan tool). (in reply to popimp) Post #: 10

RE: 93 Intrepid will not start...Please Help - 2/13/2008 5:58:52 AM    afmangel   Posts: 3 Joined: 2/2/2008 Status: offline Hello, I hope this may help you. I have a 94' Dodge Intrepid, I too was having problems with mine and just now got it fixed. First I have a question. When you changed the cam sensor did you take the negative battery cable off? That is a must, I changed mine and it was cranking, but later that evening it started not starting again, so I changed the crankshaft sensor. My car is actually running rather well now. I have a Chilton repair manual for the 93' - 97' model. The cam sensor will give the give 54, but the crankshaft sensor gave the code 11. You can use a voltemeter to check your sensors. The voltage needs to be between 8-9.5. If it is lower than 8 or higher than 9.5 then there is a problem in the wiring or related components. It also says than you can reset the codes by turning the key on and off at least 50 times. That should reset them. If you have unhooked the negative cable you should also be getting a code of 12 and the code 55 is the end of the test. (in reply to kurts2) Post #: 11
