2018 RAM 2500 Oil Pressure Sensor

[Compton]

Hey, guys need some help here.

Recently I was towing in my 18 RAM 2500 4x4 and lost oil pressure and quickly pulled over and checked everything, and all was good and made it home and parked it.

I checked the sensor the next day, pushing oil through the sensor into the connection.

I also noticed the wire to the connector seemed kind of rubbery, feeling like it was hot. I went and bought another one, and all was good for a few days now it done it again—the same thing.

I looked on Geno's garage and noticed their sensor listed for my truck has a sleeve with a bolt that goes through, and the sensor screws into this. (Like a snubbed valve, maybe?) my truck doesn't have this; it just screws indirectly.

Could this be the problem?

Thanks

The picture appears to be a banjo bolt and fitting with the sole purpose of changing the stock mounting location and angle of the factory sensor.

Oil does penetrate and weaken wire insulation over time.

Once cleaned, the wire still feels softer than the surrounding wire, you should replace this portion of the harness to prevent shorts, and excess heat is generated when there is a connection issue sometimes.

Many sensors, especially oil sensors, will come with a replacement harness stub for this reason, in case it is necessary to replace it.

At least they do at advance or O'Rileys or the like im not sure about the dealers (probably not.)

If there is oil passing through the center of the oil sensor, this generally seeps into the center of the plug and may build up pressure, and if the seal is good or the plug is weak may actually force the plug apart and unplug itself even if the sensor is still reading properly.

A new sensbad sense is uncommon, and someone slipping a used sensor into a box for a refund is more common.

However, if you replaced an oil pressure sensor and are still experiencing oil seepage, the centplug's center replacement sensor is bad and should be replaced.

be careful when installing the sensor not to over tighten the sensor to any extreme or to distort the sensor itself as i suppose it would be possible to break a seal if the body was weak, though admittedly, I have never seen one fail from this, and i would be the one to have tried

Thanks, man.

I'll order the sensor from @Geno's Garage.

As stated before, the current sensor that in there doesn't have the banjo bolt and different angle so hopefully, it will fix my problems.

Well, I can't seem to figure this out.

I installed the @Geno's Garage oil pressure sensor, and now it has taken a dump.

So this will be the third sensor that goes out on me.

Idk what's going on.

all of them are blowing oil thru the sensor and causing it not to work

After looking around, I think I'm going to try and trick the dash into thinking the sensor is reading and install a mechanical gauge.

I would have an actual reading then.

I know the current oil pressure sensor only has one wire going to it.

If I ground it out, that should make the gauge read, right?

Hopefully, someone will know.

I also need to find the right type of bolt to delete the sensor.

Any ideas?

At this point, I think a mechanical gauge is a good idea.

I can't imagine why the pressure sensors are blowing out unless, for some reason, your oil pressure is exceptionally high.

I wondered if there is a relief valve on our oil pumps, and if so, yours may be stuck.

You will need to measure the threads on the oil sensor and see if your gauge will fit where it went or plug it and then thread your gauge into the 1/8" NPT port on top of the oil filter.

Either way, as you say, you will need to satisfy the pressure sensor wire by grounding it.

I am bringing this back alive.

I am having the same issue.

3 cracked oil sensors in less than 800 miles towing heavy.

Was there ever a solution to this problem?

We were only using this truck as a backup to a 2nd gen 1 ton, and she hasn't broken down for a while now, knock on wood.

So I haven't been towing with it.

I never found a solution, and I know that if I use it to tow, it will happen again.

I was towing pretty heavy for a 3/4 ton; maybe that had something to do with it.

I'm sure we were over what it's rated for; we were pulling 25000 pounds, but I ordered a bolt to put in the spot of the sensor and will bypass that sensor if I use it again.

I'll keep an eye on oil temps.

Thank you for the response.

My truck is a 3500 dually, built for over 30,000lbs.

I am hauling a 26,000lbs fifth wheel toy hauler, same issue.

I did install a Pacbrake oil relocate kit before these issues started.

I wonder if that is building pressure by this sensor for some reason and causing it to fail.

Any chance you have a relocation kit on your truck?

I also wonder if the oil pressure relief valve is a potential problem for us.

I am trying a napa sensor (3 Mopar ones failed) with hopes the issue does not repeat itself but also of the opinion it likely will.

I think to be safe, when and if I get home with this truck, I will block that hole off with a bolt and install a gauge to monitor the actual pressure in the truck.

I wonder if I can install a sensor that will talk to the MM3 allowing me to set alarms around the pressure and temperature.

Same here as I have the relocation kit too.

That might be the problem, it has to be.

With yours being a 3500 and pulling more weight, that's not the issue.

I know the relief valve you're talking about, but I've spoken with several Cummins guys who hardly fail or go bad.

I was going to run a mechanical gauge on mine; if I did put one on it not sure about MM3 and oil sensors.
