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: 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. | |
 As you may have noticed, we are reorganizing the Forums to allow better focus and easier searching when you have a particular problem or comment about any given vehicle. Many of the large generic discussions (like this one) will be closed to new posts, and we ask that you continue in the more focused discussions that you can find at the Group page for the vehicle, linked below. This discussion will not be deleted, so you can still search for information in it. We recognize this is going to take some getting used to (for the hosts too!), so please bear with us. If you have any questions, you can always email the host of any discussion - the link is at the top of each page to the host who oversees that discussion. If you don't see a discussion in the group appropriate to your question or comment, start a new one, or send me an email, and I'll point you in the right direction! Thanks! kcram - Pickups Host Dodge Ram Group |
