PLEASE LIKE AND SUBSCRIBE IF YOU FOUND THIS INFORMATION HELPFUL! It is SO appreciated.
To be clear - this will cause a crank, but no start condition. May also cause an extended crank, but will start situation. Has no effect on your starter motor.
You may, or may not get a p0336 code.
This was a 2016 Ram Ecodiesel. You should verify your part numbers with the official mopar parts site, but mine were:
1) crank sensor 6849 0180 AA
2) reluctor wheel 6858 2742 AA
This job can be done on the ground in your driveway or garage as well, if you know what you’re doing.

To anyone who would ask or mention it, yes, there is a recall for the the crankshaft sensor. No, it is not a proper repair. It is simply reprogramming the engine to continue running off the cam sensors when the crank sensor fails, so the vehicle doesn’t turn off while driving and cause an accident. They will not pay a tech to replace the reluctor ring, they just want to cover themselves and prevent injury/accidents. The part will still have to be replaced properly in the long run. Aside from the check engine light staying on, I would imagine drivability issues would still exist afterward, possibly limp home mode, etc, but I can’t say for sure.

Great video. Is this repair fixed under warranty, even after the factory warranty is expired? Currently, they offer only one fix: a flash of the software. How often have you seen this happen? What percentage of Ecodiesels will this happen to? I have a 2016 Ram Ecodiesel. thx

If you have a powertrain warranty on the vehicle, they should cover this. Otherwise, yes your correct, Chryslers temporary fix is to program it so the engine can continue to run off the camshaft sensors, instead of the crankshaft sensor. I believe the truck may go into a limp mode afterwards, but I can’t say for sure. They are more concerned about the legal aspects of someone getting into an accident if the engine shuts off unexpectedly. I would say it will happen to all Ecodiesels eventually. I think environment plays a large factor in the magnetic strip delaminating from the steel ring (humidity, salt, long periods of sitting, etc). You could wait it out, or be proactive and take care of it before it’s an issue. That being said, who knows, your truck might live out its lifespan without it ever failing. It’s really hard to put a percentage on it.

hi, question, does the crank sensor issue afects the desired fuel pressure at all? meaning at high pressure cp4 desired pressure?

@tadsworkshop 2 ай бұрын

To the best of my knowledge, no, it should have no influence on fuel rail pressure.

Offhand, I can’t be sure, but I think it is about 100ft/lbs. find a verified source. I use my best judgement, some loctite, and a criss cross pattern, torquing in stages, and evenly.

Hello, 2014 GC EcoDiesel, we just replaced the alternator plate diodes, then drove it for 3 days with no issues, then we topped off tank, drive it home, now it wont start (just cranks) and no codes. Any recommendations please? Thanks.

@tadsworkshop 4 ай бұрын

Two most common things would be lift pump in fuel tank, or crankshaft sensor. Measure fuel pressure between lift pump in tank, and injector pump on engine. I have a video on this. Should be 55-60psi. If not, probably a failed lift pump or plugged fuel filter, or it’s not getting power and ground. The computer does not measure this, only injection pressure. Injection pressure should be at least 3500psi while cranking. This can clue you in to a problem with the low pressure, 60psi lift pump.

I have p0336 code. Extended crank(approx 3-6s) with START. Runs great after it starts. Could this be the issue?

@tadsworkshop Ай бұрын

Absolutely. Get on replacing the reluctor wheel and the crankshaft sensor.

I have a 2014 ecodiesel..my mechanic said something melted inside the crankshaft..I don't believe that I think it's the crankshaft postion censor. Mine has a hard start. Stalls when I drive it..what do u think the problem is?

@tadsworkshop Жыл бұрын

With a scan tool, I would see if there are any trouble codes first. If not, I would watch injection fuel pressure during the hard start, via the scan tool.

I thought this was a recall issue, should this be covered by manufacturer?

@tadsworkshop Жыл бұрын

The recall is a bad joke at best. It’s reprogramming of the computer, so that, instead of the truck dying in the middle of your drive, the truck will actually still be able to limp you home and start back up again using the camshaft sensors. I don’t know for sure, but I’d imagine driveability issues would exist, and the engine staying in limp mode until the sensor and it’s ring are replaced. They do not want the expense of paying technicians to remove transmissions to fix the problem properly.

@tadsworkshop Жыл бұрын

What repairs did they do? This crankshaft sensor, or something else? If if was after replacing this crank sensor…..they need to go over the cable that attaches to the driver side, and the main electrical connector on the transmission, on the passenger side. It’s also possible they damaged the electrical harness when reinstalling the transmission.

my engine stopped working after hearing that cranking noise on highway. could this be due to faulty crankshaft sensor? besides i had that electric throttle light on also. My friend who is a mechanic said engine might be dead. What do you think?

@tadsworkshop 5 ай бұрын

Not sure what your referring to by the noise, but that is concerning. At least the subject matter of this video, the crankshaft sensor and its reluctor ring, would not make any noise once they fail, just simply stall out and engine will crank over endlessly without starting. Look under your engine. If you see a substantial oil leak from the rear of the engine, that would be a sign of crankshaft main bearing failure. Let me know what you see or are experiencing.

A new recall for this.

@tadsworkshop 7 ай бұрын

It’s just programming, to allow the engine to continue running off of the camshaft sensors, and allow you to get your truck home or the dealer. It prevents shutting off while driving, so as to avoid an accident. They are trying to cover their ass, not help you fix the issue. You’ll still have to remove the transmission at some point and replace the crankshaft sensor once it fails.
