Dorman 904-6030 Nitrogen Oxide (NOx) Sensor Compatible with Select Ram Models

It’s a hit or miss with this brand sensor. I got one about a year and a half ago and worked fine for about a year and a half…. I just ordered this new one and it worked fine for a couple days and now the code it is back! The frustration is not even with the defective part… it’s with the ability to reach the part and remove and replace it! It’s a crappy spot, remove wheel well cover, remove tire and use special socket made for this things and man oh man it’s pain in the neck!!! Ugh. I’m returning it and just getting it done at a local shop, I rather pay more money than have to reinstall another one again. Oh, and it should last more than a year and half. It’s an expensive part, why does it go out after a year and a half!? And the fact this this one only worked for a couple days is worse. UGH, SO FRUSTRATING!!!!Update: I used the item for a couple weeks before returning. I had to plug and unplug every few days. Code kept coming back. Save yourself the headache and get another item.

Great replacement product for the value, recommend professional install unless ypu are will to tackle the task. This price bears the dealers price all day

This is NOT the downstream NOx Sensor. The rear / downstream NOx Sensor is a flat 4 pin connector, this is a 4 pin square connector.

Seems good so far

I ended up buying this sensor for my 2014 ram 6.7 Cummins because my factory one failed at 63000 miles. Installed Doorman nox sensor and after the truck ran all it's diagnostic monitors the check engine light came back on. Contacted doorman they couldn't really do anything but possibly exchange it. I couldn't wait any longer cause my smog was gonna be due so I purchased the factory mopar unit at three times more the cost but it solved my issues. I dont know why the doorman wouldn't work on my truck. The fitment was great but would not function correctly. Possibly defective.

I'm giving 2 stars because the sensor will not work on my 2013 Ram 2500 with the 6.7. I had a Nox code after 54k miles. Dealer wanted $1300 for sensor. I found the cross reference number for Dorman and bought it for alot cheaper. Apparently Cummins computer doesn't recognize after market parts so it coded again. Took to dealer and had OEM sensor put on and everything works fine. Nothing against Dorman, but some things you have to buy original. I did get to return part for refund.

Perfect match. Works great

Died immediately. Do not waste your money on this product, I ended up spending 1000 to buy an OEM part to replace this.
