Ok just drove home from DODGE and the truck ran like a dream, no check engine light... I just dont understand why one day it works fine, and another its bad... Im here in Nebraska and the weather is always changing... its like 30 today so its pretty warm, however its been really cold out? so im not sure if that has an effect....

Here are the codes it WAS pulling yesterday P0132 p0135 p0141... they all lead to a bad o2 or bad PCM, or jsut bad wireing... either way any 2 cents is welcomed here, thanks again....

 

It's a dodge, need i say more ? lol dude our trucks are like women you cant live with them and you cant live with out them

 

Do a search for closed loop and open loop. You might find some good info. It sounds like you've got a bad sensor and it is sending the computer screwy. Or maybe a bad connection or ground is causing a fault. Start checking those too.

 

Aubrey where the hell have you been, aint seen you on in a bit

 

Yeah, maybe his truck was just on it's period.

 

lol nate

 

I tried to get the NTKs for my truck even though they were a little more expensive. Problem was that my truck lists two different part #s, one for the left and one for the right, and no one stocked the left one, only the right one. Probably has to do with the wire length and not the actual sensor. When I saw that Denso was the OEM manufacturer, I figured I couldn't go wrong with them and they were about $9 each cheaper.

 

I didnt know that Denso was the OEM. Where did you see that?

See, I was gonna buy just a new front NTK sensor from Hughes Engines for $49. The Denso ones on Rock Auto are $32-$42. But there is about six of them. The NTK sensor for my truck is P/N 23151, and that cross refrences to Denso 234-4076 and 234-4077. The differences between them is the wires on one are 13 inches long and the other is 22 inches long. This is confusing! But I will just measure the wires this weekend. Thanks for the insight Rick!

 

Nate, I can't remember where I saw it because I looked at so many sites, but the Denso site confirms that they are an OEM supplier. The reason there is so many listsed is because A) there are pre- and post-cat part #s, B) there are some applications that have different left/right part #s, and C) they also sell universal part #s for pre- and post-cat fitment.

IMHO, the universals are not worth the small savings. These trucks use O2 sensors that are heated and vented through the wiring harness. It's not worth it to try and do your own connector unless you have some strange exhaust system where a standard length sensor won't work.

 

Yeah, I found out that the 4077 sensor is for a California truck that has a left sensor. The 4076 sensor is the one I want because it is the right sensor. My Federal emissions truck only has the right sensor.

Maybe when I change them I will do a simple DIY and have a huge cross refrence for both NGK and Denso sensors. That'll be fun to get all written down!

Universal sensors are a waste of time.
