I have a problem for all you experts out there. My 1999 Dodge Ram 1500 (5.2L Auto) got a check engine light two days ago. It had been fine the day before. In drive, the truck starts slowly (no power, torque converter?) up to about 10-15 mph and then drives normally there after. If I romp on it, I get power but it tachs out 1st gear until I let off the gas and then shifts into 2nd for a very short time. If I'm not going fast enough when I let off to force it into 2nd it will shift back into 1st at a very high RPM. After romping on it, it will behave this way (tach out 1st, short shift in 2nd, etc.) until I shut it off and restart it and then it goes back to having no power at takeoff but otherwise behaving normally. I had the code scanned at AutoZone and they got a "Manufacturer's Code". The guy there tried to reset it but it just came back. He then told me to unhook the battery and hold the cables together for thirty seconds and it should reset and run properly. I don't think he knew what he was talking about because even though this did reset it it just came back within 10 secs. Any help would be greatly appreciated.

Replying to: pegleg95 (Oct 11, 2006 11:57 am) A 'manufacturer's code' is a non-standard OBDII code and so cannot be identified by a generic OBDII reader. Any code is there to notify you of a problem.........the code itself isn't the problem. Resetting the computer to remove the code doesn't fix anything, as you've found out. You have to fix the problem that caused the code, then do a reset to remove it. You need to have the code read by a dealership, or an independent shop that's a Dodge specialist.

Last night for some reason my keyless entry quit working and when I put the key in the ignition, the truck will not turn over and the anti theft light starts blinking and keeps blinking for several minutes after you take the key out of the ignition. Do I have a problem with the anti-theft system |

Replying to: mac24 (Oct 11, 2006 12:10 pm) FYI - I knew that the kid at AutoZone was a moron but was willing to try anything because I am trying to sell this truck and don't want to sink a bunch of money into it first. I should have traded it in a week ago when I was at the dealer (and the truck was still trouble free) but I thought I could do better. |

I have a 2002 Ram 1500. My check engine light came on so I went out and bought one of those handy dandy readers. When I checked for codes it came up with P1491 which equates to Rad Fan Control Relay Circuit. I take it the Rad is for Radiator. But in looking online I came across this web page that said… “An occasional problem on this vehicle is the failure of the Condenser Fan Motor (4.7 VIN N and 5.9L VIN Z engines only). This problem may cause the Check Engine Light to illuminate.” This came off of autos.msn.com vehicle ratings page. I have had trouble with my AC the last few warm days that we have had. When the engine is idling the vent blows warm moist air, so I am thinking that I need a new compressor. My question is could the failure of the condenser fan motor or the compressor cause the P1491 code.  Thanks for the help.

Replying to: cpennison (Oct 16, 2006 7:09 am) Why assume the worst? It could just be low refrigerant.

Replying to: mac24 (Oct 16, 2006 7:27 am) I have already checked the refrigerant and it is fine. Only at first was I assuming that the compressor was going. Then the check engine light came on with a P1491 code (Rad Fan Control Relay Circuit) and I was wondering if that could case the AC too work only during normal driving. There was also the quote about the condenser fan motor, and I was wondering if that would also cause a P1491 code.

| Hope someone can help with this one. I have an 01 1500 series with overdrive and transmission always appears to want to take off in third gear. The code comes up on the scanner as a P-1762 govenor pressure sensor. | |
