2016 Dodge Challenger SXT Plus 3.6L (G ERB) 8-spd (845RE)

We have replaced oil pump and pickup, did obvious changed oil filter and housing both oil pressure switches and oil temp switch . Re ran wires to pressure solenoid to ecm 2 wires at sensor 1.8 v at idle. Reran oil pressure wires under intake 5 volt reference, ground and sensor also showing 1.8v can not find a correlation between acceleration, ( throttle body?) or pedal and oil pressure . Oil pressure on whet gauge never goes below 16lbs. FCA says it’s a wiring issue on tech authority Where? I’ll gladly RE wire. Anyone else run into this P06dd is code Did wet pressure test also showing minimum 20lbs any help on either ohming out or a waveform would be greatly appreciated

so I guessing the throttle body is non responsive cause of engine reduce mode, any codes?

Ive changed the pig tail for the oil pressure switch as well as new oil filter housing. I had the same problem with a chrysler 300 3.6l

P06dd code? Re wired switch both one on intake and one on right side of block

It’s got to be wiring or sensor mechanically good pressure.

Car will accelerate to about 3400 rpms and feel like it’s banging off of rev limiter po6dd is code which is a secondary pressure solenoid cutting out the throttle you’ve either run into before or you haven’t we have this one is baffling

So what does the scan tool show for oil PSI in engine data with koeo and engine running?

At idle at 200 degrees 16 lbs at 1800 rpm 65 + used versus, maxi Sys , Zeus, computer with pass thru doesn’t matter what data I look at it’s not mechanical , gauge in car reads within 5% . I can turn off traction run on lift it won’t do it . Wondering if harness separating somewhere under acceleration or signal interrupted. I stepped away because I feel I need to re think issue trying to come up…

I doubt you have a problem with the pressure sensor. The PCM runs that diagnostic 1st and if it fails it doesn't even check for the P06DD. P06DD takes 20 seconds of low oil pressure to set. But it is when the dual stage oil pump switches to high pressure mode, over 2800 rpms. In high pressure mode, you need at least 45 psi. If not, rpms are limited to 3300 when the code is active. The things…

Tried 3 different type oil filters, new oil pump, checked O ring and replaced twice , new oil pump.

I've seen a few of these with backed off galley bolts as well.

Have had this problem with multiple 3.6 Chrysler’s, there was a problem with oil pumps in some, they have a sensor in the pump that is troublesome. Make sure your replacement pump isn’t aftermarket, even if from the dealer. More than once the replacement pump caused more issues than the original

Remove both valve covers and inspect the oil galley plugs behind the phasers on both heads, see picture. You can get to them with with a quarter 13 swivel. If they have fallen out they usually can be found laying on a lower ledge of the timing cover, thankfully they can be retrieved with a magnetic. They only need to be tightened to like 10 or 12 ftlbs. When these get loose or fall out it can…

Hey John, I live 10 minutes away from you and I'd be happy to stop by to help, or most of all, if you figured the problem, I'd like to know/learn exactly what the solution was. My opinion is that another sensor has a 5v issue pulling done others.

I know you said you ran new wires but did you run them from the connector. I had a van with this same code and the wires were frayed and shorting together at the connector on the harness side where is plugs into the pass thru on the engine block. Had to remove a bunch of wire stays to get to and repair the wiring, once I got the harness out I could see the first inch of wires had the insulation…

In Engine Data on 2 speed pump we get high pressure it showing on even though oil pressure comes out of parameters

I’m going to pul the intake for the 4th time and re wire plug in morning also I’m going to change oil pump again . I was hoping to be able to scope and come up with an answer

The normal oil pressure on these is over 139 PSI when cold. Do you have that pressure? I don't see it in your post. Above about 3400 RPMs the PCM commands different pressure, once the temp gets about 140 degrees. Do you see the change? This is NOT about the solenoid, but about what the PCM wants to see when the pressure is commanded to change…

Not sure where you got that data tech authority says at idle can’t fall below 6 lbs over 2800 rpm 2nd stage kicks in and pressure is 65 lbs . The solenoid should turn off and allow the second stage to engage. Haven’t seen many normally aspirated engines in my 40 plus years with 140 lbs of oil pressure that some great oil seals

That is the minimum pressure so that the engine doesn't blow up! The PID for pressure is in the scanner. Has the two stage pump. Lots of posts about this code on the ‘other’ site. Have diagnosed bunches of them. Once the temp gets to about 140 degrees, it will command the change when VVT is active, and that is around … RPM. The first time I saw that oil pressure, I believed something…

Thanks made us look and ask more in depth questions not sure why FCA doesn’t give factual data. We could have resolved about 40 hours before, I guess that’s why they call it experience.

So it’s fixed after chasing all the gremlins it was determined we had the wrong oil pump. It was from the FCA dealer but the pressure switch was incorrect or the second stage pressure we never really got an answer.. We replaced the pump but we also dropped all bearing caps for inspection all were good and we RE cleaned with wire brushes and air all oil ports. Everything was fine no codes and oil…
