Kind of odd to get 2 different readings on codes but i got a P0432 on 3 key turn ,an a p2000 on my Elm tool.
02 readings dont look too off .
What should i look at with 02 ST bank 1 reading... .had-3.9..short term b1 long term b1 an b2 stayed steady an on same range ..or maybe test cat ,etc?
Its 01 3.9 2wd ...I hope I wont need a new cat !
thankfully next year no more emission testing here..lol [ got 2 months to fool with it]
O x trap...odd but elm read that

 

I wasn't aware these trucks even monitored NOx...... Interesting. How many cats does the truck have?

 

Yea this is odd for dodge ..
Saw 2 cats there at engine w the 4 sensors an individual cat before muffler [ 02 sensors not near last cat before muffler .]
02 before an after on both sides at engine ..

 

Think I would clear the codes, and drive it for a bit, see if anything comes back.

 

Didnt reset ...
Maybe a fluke .I rechecked wiring an retightened gas cap an reset ecm..went 100 miles today in errands with off an on starts an NO code... very weird..
Hopefully it wont come back ..I gotta take it thru emissions soon ..but never again after this year as its stopping soon an no more .👍
Im gonna look at replacing plugs an a few other things also.
Still stumped on p0432 ..weak 02 or connector maybe
Is that code the drivers side or pass side ...bank 2 downstream ?

 

Passenger side, after the cat.

 

Do you have two sensors front and two sensors rear, or just one sensor rear? If two in the back, switch them and see if the code follows the sensor. If it does, bad sensor, if not then check for a pinched wiring harness around the transmission. Two days of driving should have been more than long enough to wear through a wire if a harness is being pinched.

 

I have 4 -2 on each side 1in front of each cat on both sides of motor an 1 in bk of each cat an non at rear cat .
Went 200-300 miles now since resecuring connectors ,resecuring gas cap an reset codes .An all is good..👍
..Remonitored 02 readings an fuel trim after a run an they are steady an even w output downstream readings both 02s about . 96 an i am fluctuating normal on both upstream .

May have been the connectors..but very odd to get a diesel only code on my Elm scanner ..lol

Still need to look at plugs though..
If i get that code again ill swap both downstream 02s an see what happens but for the 300 miles an running good I dont think its ongoing.Seafoam .got rid of anything that may have factored fuel .
Thanks
