Works fine on Dodge for parts

Replaced a faulty P0141 O2 sensor with a Bosh but got a different engine code this time P0138. I read that Dodges don't like Bosch O2 sensors so I used this Denso based on another reviewer. This works on a 2005 Dodge Durango 4.7.

Pros
  • good thing
Cons
  • functionality

Buy this brand if you have a 2005 Dodge Dakota

Works as it should. I originally bought Bosch sensors, but my 2005 Dakota didn't work well. Someone on the forum said they had the same problem and just decided to try the Denso brand and after that the truck worked fine. I have the same problem.

Pros
  • Absolute Legend
Cons
  • Poorly thought out

See packing list

If you have a Dodge Dakota this description is NOT complete. There is a left and a right side. To help people who may be in the same situation as me, part number 234-4756 is for Right Upstream (Gateway) and Left Downstream (Driver). Part number 234-4744 is for the lower right (passthrough) and upper left (driver) channels. Someone needs to update the list of these things.

Pros
  • Great for a small home
Cons
  • I vaguely remember

Short sensor cable

Fits my 2006 Chrysler Pacifica but the cable was a few inches shorter. After receiving the wrong sensor in the correct box I didn't want to waste any more time sending it back so I cut off the old sensor cable and connected the old connector to the new sensor to extend the cable. It was a bit of a shame to get something that said it would fit, but to save some money they made the cord a few inches shorter.

Pros
  • Best in the niche
Cons
  • Problem
