Throttle body issue?

[squirrel30668]

I have a 2004 ram 1500 with the 5.7 hemi and a this morning I was driving and the check engine light came on along with the flashing red lightning bolt. Truck was still idling smooth but had absolutely no throttle response. Pulled over and even when I was stopped the idle was higher than it was supposed to be so I put it in park and turned it off. Immediately started back up and ran fine the rest of my trip. Pulled the check engine code and it's p2175. The other day I also had code p0440 pop up which is emission related. Cleared it and it hasn't come back yet. Anyone know what I may be looking at? So far I'm reading everything from dirty throttle body to map sensor. Anyone have any insight on this?

Right off the bat I would check the air filter to make sure it's not packed full. If it's dirty it should be replaced but it would have to be pretty bad to cause this issue, use your judgment if you think it's the cause. Second, I would pull the intake hose to get access to the throttle valve. Rams are known to clog up the throttles so it's very possible, and a couple minutes with a rag should get it clean enough.

If those don't work, its possible its a MAF issue. The wire that you have to disconnect to get the intake hose off, that wire goes to the MAF. They can get dirty and sometimes cleaning them will help, but they are cheap and easy to replace so its worth a shot.

Last, the throttle position sensor could be getting flaky, I don't know that I've heard of it happening before but it's always a possibility.

So from what I know my truck don't have a maf sensor but does have a map sensor. The tps is built into the throttle body. I went ahead and ordered the throttle body with tps built in to kill 2 birds with one stone. Truck only has 120,000 miles on it and has sat a good bit in the last few years as is was owned by an 80 yr old vet who had bought it new.

Good looking truck I think
