How to Replace the Crank Sensor on a Mercedes ML320

[@mtebaldi1]

Thanks Brian for a great DIY video. This gave me the the location and tips on the best way to change the CKPS on my 2005 ML350.

[@SouloftheTroll]

By far the best video on KZbin about this job! Thanks so much! Clear, concise, and to the point!

[@HowtoAutomotive]

@@SouloftheTroll thank you!

[@Koya_Sipanlog_Express]

replaced mine successfully. I hope no more traffic stop or intersection stalling. Thank you!

[@dannyninerempire]

I was about to spend $200+ I'm going to do it myself and spend only $55 :)

[@HowtoAutomotive]

dannyninerempire very cool thank you for sharing!

[@DaytonCarCare]

$200 it swap out a CPS that takes about 5 minutes to do. Cha-ching lol. Just serviced an Audi S4: radiator, AC compressor, intake manifold seals and oil check valves, oil/filter change, and an engine mount. Total labor $500. So $200 to do a simple CPS, yeah kind of pricey.

[@carolmcenteewhite8962]

Brian you are a jewel it went great super fantastic I am rolling thank you so much I just found a BFF!

[@HowtoAutomotive]

Carol that makes me happy to hear! Great job!!

[@benbrown9053]

Did your husband do it

[@whatspoppin313]

Someone just tried to charge me $250 to change this! 🤣🤣🤣

[@MacAutoDiag]

What engine is this

[@pcinoregon]

Excellent video..thanks..you just don't know

[@jeremytaylor4576]

Changed mine. Ran before changing it, now won’t start with new one in.

[@jimbrown3770]

Hey Brian I have an 05 ml 350 and I threw a code for the crankshaft position sensor. Is it pretty much the same as the one in your video? Also, is there only 1 sensor? Thanks for your help and your awesome videos

[@HowtoAutomotive]

Yes there’s only one crank sensor. And it’s very common failure part.

[@jimbrown3770]

@@HowtoAutomotive could you tell me the part # by chance? I clicked on your link to Amazon and it's not working for me.

[@caliaska4670]

Thank you so much Brian! This video is the biggest help for me to fix my ml320.

[@Wilt8v92]

Is the ML430 in the same is it?

[@brooster87]

Sorry again. Auto correct. Crank sensor.

[@jamespt2005]

Thank you I’m gonna try to replace mine because it’s not starting

[@HowtoAutomotive]

You got this!

[@carolmcenteewhite8962]

Ok Brian I will check it out.

[@Luisperez-dc1kn]

Thanks for the great video

[@HowtoAutomotive]

Luis perez thank you glad to help.

[@garyyung1297]

very helpful video, is it true that crankshaft position sensor can go faulty even without engine light coming on? thanks

[@HowtoAutomotive]

Gary Yung yes see it a lot. The car will have an intermittent stalling symptom or a crank no start.

[@RennaeFord]

Can you post a video on how to use the jack for the 1998 Mercedes ml320?

[@HowtoAutomotive]

Rennae Ford if a ML comes in the shop I will.

[@rw7051]

I have mercedes gl350 diesel. jerky transmission when cold. p0336. FIXED. Best from underneath. TAke the plastic shield from below the transmission pan off, using 8mm wrench. Look above the starter and the LH fwd drive shaft and you'll see the plug on the driver side where the engine meets the transmission. It's at the 10 oclock position, just like on the Sprinter. I have a GL350,2013. crankshaft position sensor. metal shield over connector. use torx box end wrench.

[@pcinoregon]

That's cool.... so this is an easier way to get to that Bolt?

[@mrneatglond3753]

What was the vehicle doing why you have to change a sensor

[@kentnoetico9867]

It will generally become hard to start when hot; long cranking and sometimes stalling.

[@garyyung1297]

excellent helpful video thanks

[@tamesheiabyrd6093]

Thanks so much a mechanic told my mom in order to change her crank shaft censor he needed to take out the water pump and it would cost her 1200.

[@dannyramos8068]

thanks buddy now I know where to start from I had no idea where this sensor was located at

[@HowtoAutomotive]

Danny Ramos glad to help thank you for watching.

[@brooster87]

Sorry that code was in addition to the Crance code. Mass air flow is what it says. Can I just clean the mass air flow or replace it only

[@grantstrong7319]

Thank you so much for your help! Three videos on KZbin teaching how to remove this fing sensor all different. I was able to copy how you removed the worst placed screw in history and succeed. My upmost gratitude to you sir.

[@HowtoAutomotive]

Grant Strong glad to help. Thank you for watching!

[@waynegomillion4976]

Appreciate it. Is it the same for an ml55amg 2000?

[@FranklinCarreroluthier]

I have a ml320 from 1999 it works normally till the car arrives its normal temperature the car starts to fail when it is in minimum, the sensor might be the problem?

[@brooster87]

Thanks man. That is a great video. Changing mine this week. I’m getting an sensor code too. P0104. Is that just a clean or replace?

[@garybourgeois7019]

Will you always get a check engine light with a failed CPS? 99 ML 320 turns over briskly but will not start. Wait 15 minutes and it will start. Has died on me a couple of times when at stop. Have checked with ODB II and get no apparent faults. Still possible CPS?

[@alanpazprado]

Signs that you need to replaced this is when engine got hotter and after you turn the car off it will not start until you wait it out to cool down ! Replaced mine already when it’s only 100000+ now im in almost 300000!

[@SteveRobReviews]

Well done Brian..

[@HowtoAutomotive]

I took your advice and turn the camera sideways. Thanks again for the tip.

[@SteveRobReviews]

How to Automotive Need any help let me know, don't know if I can help but it doesn't hurt to ask LOL

[@succatti73]

Thank you!!!! I like to work on my own car and you're saving me!!!! GOD bless!!

[@colinaglae2605]

Thanx Brian, for your brilliant video on the on crank shaft replacement on Mercedes M320 !!

[@mataataata7490]

Thanks for the clear information I live in American Samoa working on a ml320, 2001 this was a great relieif

[@reza49363]

hey amazing video, my question is why do we replace the sensor, i have ml320 1999 and every thing works it just some times the engine stops and i have to wait for 30 mints or reset the battery then engine starts i have no killed switch or any starter or alarmes i saw you video but my question is this the sensor malfunction and must be replace? thank you very much

[@HowtoAutomotive]

Reza Ahmadi stalling is one of the symptoms and no star is another symptom. There usually is a code stored in there PCM for the crank sensor.

[@pimpoutmysandwich]

According to my AutoZone assessment, "when not replaced, vehicle may experience no start, hard start, intermittent engine shut down, misfire, engine cut out, excessive fuel consumption, CEL illumination, and/ or failed emission test" because the sensor helps regulate "ignition spark timing and fuel injector pulse timing" which is very important to maintain if you want to keep your engine running healthy or running at all over time.

[@VINTAGEDS]

Great video. Do you you need to disconnect the battery before making this fix?

[@KS-cu1zc]

Hello Brian is this for gas model or diesel bluetec same location same sensor. Thx great video

[@brooster87]

Thank you so much. Just did mine today. Great instructions.

[@acmehighperformance2826]

Do these run in open loop if you pull it, unplug it and crank?

[@eastside851]

My car lags when starting after sitting about an hour or two is this why? It has a bad crank sensor?

[@ClintonSnow]

What's the part number of this crankshaft sensor? where can I buy the original crankshaft sensor for Mercedes Benz ML430, V8?

[@HowtoAutomotive]

Clinton Snow there is a link with the part number is in the description of the video.

[@SpenserRoger]

Lucky you have the v6, the v8 is way shoved back there.

[@iantoriani791]

Good simple directions...Does the ml270 w163 2002 have the sensor in the same position?..Ianto.

[@HowtoAutomotive]

Ianto Riani I don’t know if the center is in the same spot. I don’t see very many diesels

[@vegetablehead]

what are signs that the sensor is going bad? my 2002 has a noticeable rough idle, but i just took it on highway trip and got 21mpg. also, a little tip on the 'vanity' cover. the left rear attachment (standing in front of engine) is NOT attached by rubber grommet, but by cheap piece of plastic clip. i know b/c i broke mine!

[@kentnoetico9867]

It will generally become hard to start when hot; long cranking and sometimes stalling

[@davidagabi2077]

hi My ML 320 seem to be having the same problems, It starts and run for like 20 mins and then turns its self off and after a 10 to 15 min wait, would start again and then repeat the circle all over again. Could it be the Crank.

[@HowtoAutomotive]

David Agabi yes it could be the season or a Fuel Pump shuttling down. You’ll need to test for fuel pressure and also for spark to determine which one is the problem

[@carolmcenteewhite8962]

Now for the next project can anyone tell me why does my car whistle and has a rough sound when it is idled or in reverse ? It's a clk 320

[@HowtoAutomotive]

Sounds like you have a vacuum leak.

[@ttaei66]

My ml320 start up then turn off I'd change fuel pump n fuel relay and put a new battery n still doesn't stay on plz need help

[@HowtoAutomotive]

ttaei66 sounds like the crank sensor is bad but without testing hard to tell.

[@achamitemiller8805]

I thank you for that tip on location

[@BrianaGettings]

What socket size did you use and what was your extension , a 3/8 drive?

[@DaytonCarCare]

Yes 3/8 most commonly used

[@karonsquaaad5571]

Is that the sensor that's on top of the transmission in the back close to the fire wall, that's the only sensor I see that seems to be the crank sensor

[@HowtoAutomotive]

KaRon Squaaad yes that is it.

[@powerbylightfutureisnow1579]

Number one best video 😂👌

[@vivittronk]

hello!!...¿you need to use the STAR DIAGNOSIS computer after ????

[@HowtoAutomotive]

vivittronk I used a Snap-on tool to just clear the codes. No reprogramming needed.

[@vivittronk]

ok thanks!!

[@aimeemontenegro8199]

What if after changing the crankshaft and camshaft on this ML320 it still does not have power to accelerate and the rpms revs but the car does not speed at the time it is accelerated?

[@HowtoAutomotive]

Aimee Montenegro The way you’re describing it sounds like a transmission issue. Start by pulling codes.

[@Bugby67]

Uh Oh😮

[@cmgjunior52]

What are signs your Crankshaft is going out or is out

[@HowtoAutomotive]

cmgjunior52 The engine will crank and will not start.

[@BriannadaSilva]

This helped for my ml350 too!

[@HowtoAutomotive]

Yes

[@carolmcenteewhite8962]

Thanks Brian is that an expensive job?

[@HowtoAutomotive]

If it's just a vacuum hose then no it's cheap. But if it's like a gasket leaking it could be expensive. Just pop off the engine cover with the engine running kind a listen for the hissing noise.

[@harrellNOAA]

You are the man - thank you for taking time to make this video Sir.

[@HowtoAutomotive]

Thank you for watching!

[@dsheniai]

What is the size of the bolt?

[@HowtoAutomotive]

Dan Shen it is a E8 female torques socket

[@carolmcenteewhite8962]

Brian I am going to try and replace the sensor by myself my husband is dead and I have no money to pay anyone to do it wish me luck lol.....

[@HowtoAutomotive]

Carol sorry to hear about your husband. You don't need luck you can do this. Thank you for writing to me and watching the videos.

[@HowtoAutomotive]

Hello Carol. How did the sensor replacement go?

[@yamnjam]

I'm doing this very thing on my 2000 ML320 and am having problems getting the new sensor all the way back in and having the bolt hole line up with the thread. You make it seem so easy. It's the exact same sensor so that's not it. There's just no wiggle room to get leverage. One of the few times I'll need a guy to help me.

[@HowtoAutomotive]

jamnjam i've seen if it's an aftermarket sensor that they don't slide down inside the hole. So what I have done in the past is use sandpaper and lightly sand the sensor on the outside to make it a little smaller and then slide it in.

[@yamnjam]

That makes sense. I thought I was just super stupid, weak, or a little of both! I can't even get it back out. Got a buddy coming by to help and I'll be taking your advice. Thanks!

[@HowtoAutomotive]

jamnjam there's not much room down there and he can be a pain. Let me know how it comes out thank you for watching!

[@yamnjam]

The sandpaper worked like a charm. Too bad the crankshaft position sensor isn't what was wrong. I inherited it and it has 230k miles so it probably was due for a new one anyway. I've got a friend with a professional code reader coming by. I drove 200 miles the other day and 10 miles from home it just lost power on the highway, started sputtering, and then died after awhile. It restarted over and over but ran rough and moved only a few feet at a time. Got it towed. Next day started up & drove great for 2 blocks. Figured it was gone. Later, it went only 10 blocks and started the whole shuttering thing again. Towed again. Cranks fine, battery and alternator are great, so I took a stab at the CPS. I pray it's something normal like a fuel pump, not some weird obscure electrical problem. But it's not the sensor and now it doesn't even stay running. Now the fun begins.

[@HowtoAutomotive]

jamnjam it sounds like a fuel pump. You can test fuel pressure when the problem is happening. There is a possibility of a bad mass air flow Sensor. Scan tool will tell you more.

[@HowtoAutomotive]

Thank you!

[@DaytonCarCare]

I've read that sometimes you can get a crank no start condition if the CPS goes bad and also won't show any codes with OBD2 reader. Have you experienced this?

[@HowtoAutomotive]

Yes I have run across that exact condition before. The car will not have injector pulse or spark.

[@DaytonCarCare]

@@HowtoAutomotive Yeah I'm working on a 99 ML430, code for IAT so replaced MAF (checked wires to MAF plug they're OK), checked fuel PSI @ 50 should be 60 but I understand it's lower when cranking then gets higher after started (replaced FP anyway since level sensor bad), cleaned tube from EGR since common for them to carbon up (210k miles on vehicle) (have a 2000 E320 that had a no start condition and cleaning EGR tubed fixed that), also swapped in a good used ignition switch key sensor, so ordering a CPS since I can't think of any other issue that would cause this condition.

[@DaytonCarCare]

OK installed a new CPS and it seemed to almost want to start. Then same symptoms of crank no start. Did some more research on M113 engine and read if it had gotten flooded by fuel prime the system by cycling the key to position 2 several times without cranking. Then hold pedal to floor and crank. That did the trick and it is running. It does have a rough idle so spark plugs next, has cheap Autolite one from previous owner and look over gapped and carboned. Going to replace with NGKs and see it it takes care or rough idle. (since TB, and EGR have been cleaned, also new Bosch MAF)

[@DaytonCarCare]

Replaced the plugs and still same condition of crank no start and also a fuel smell. The old plugs smelled of fuel too. On further investigation I started wiggling the key then pushed on the main power plug going to key assembly then it started. Depending on where I pushed it, it would either make it start or (if running) would shut off if I pushed on it. So going to replace the ignition switch PN 1685451004

[@HowtoAutomotive]
