Mercedes Benz W210, W220 No Start - Crankshaft Position Sensor DIY

[@Rhaspun]

I just replaced my crankshaft position sensor yesterday. It was for a 2001 CLK55 AMG. After fiddling around with different extensions I ended up using a 1/4" ratchet with a two inch extension and the socket to loosen the bolt. I broke the bolt loose with the ratchet and used just the extension and socket to finish taking out the bolt. I was able to squeeze the bolt against the socket to prevent it from dropping while I was lifting the bolt out. I used superglue on the socket and bolt to keep the bolt in place so I could install the bolt back in. I found that it was easier for me to put the bolt through the hole in the sensor and then install the sensor and the bolt as a unit. The bolt will be in the correct position for the bolt to be twisted in to get it started. After I pushed in the sensor a bit I started turning the extension to get the bolt started. I twisted the bolt until I could feel that I needed to finish pushing in the sensor completely which I then proceeded to do. Then I focused on finishing up running the bolt in. I then followed up with tightening the bolt down using the ratchet. I could barely see the sensor from looking at it. But once my hand gets down into the space I couldn't see it at all. I relied on my sense of touch to finish doing the job. Overall after I was done it wasn't that bad of job to do. It took some back and forth motions for a bit until I came up with a solution that worked for me. I thought I was going to have to take the car in to a shop to finish this job. I wiggled the socket a bit to crack the superglue apart to get the socket out. Before I replaced the sensor. The engine would warm up in a rough idle and when taking off the power could be weak and it actually felt like it wanted to die. When I came off of the freeway the idle was rough. Fuel mileage dropped lower than I expected. It's odd my scanner didn't pickup the faulty crankshaft sensor problem. I only knew it was the crankshaft sensor after the engine died. Then the check engine light turned on. I was also getting an upcoming engine code problem from my oxygen sensor. It said it was having a problem warming up. The new crank sensor fixed everything for me. The upcoming problem code for the oxygen sensor warning didn't show up after replacement of the crank sensor.

Thanks for sharing your experience in such detail.

[@MrAsmith1583]

Thanks Masood. Using your instructions I was able to switch out my CPS after getting code P0355. Using your socket extension idea I was able to replace it very quickly. Also, FYI for anyone doing this, I have a 2002 S500 and I bent the protective metal shield out of the way a bit to get better access. The new CPS (BOSCH) was too large so I used some sandpaper to reduce the profile so it would slide in. Also when installing the CPS, use a small piece of tape to secure the bolt to the socket so it doesn't drop out when screwing it back in.

[@masood-tv]

Hi, glad to know it worked for you and thank you.

[@reneefink3741]

Excellent diagnostic, All the information without extraneous noise music very concise.

[@masood-tv]

Thank you very much, Renee.

High quality video and with all the detail, good job man! Thanks! :)

[@masood-tv]

Thanks, Ray.

[@patioche]

Yes you helped me. It happened to me this weekend..on my E320. Engine stopped while driving. Was not able to start. Then started after few minutes. I found this code P0335 this sunday on my scanner. And so check the code then your video... Will take care of it tomorrow. Subscribed to your chanel before... Thank you P.

[@masood-tv]

Hi Patrick. Thank you.

[@mikej5541]

This happened to me yesterday, except I was driving when it happened..I'm just happy I didn't crash the ol c55. Awesome video!

Thank you, sir.

[@aidenater]

Thank you, this is very helpful. And thanks for not using any music. :D

Hi Aidenater - you are welcome and thank you.

[@tedlu008]

Nice video. Need such a long extension

[@masood-tv]

Thanks, Ted. Yes, you do.

[@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. sep.3

[@masood-tv]

Thanks for the tip R W.

[@AgentFoxMulder1972]

hi, and thanks for the video... on the c320 it is harder to reach!

[@masood-tv]

Hi John, yes. Need a helper with even smaller hands. Thx for the comment.

[@unfadeablecivic]

My w210 is doing this but I have no check engine light on. Is it possible to get no codes and still have this sensor problem?

[@masood-tv]

If you haven't changed your CPS in the last 70K miles or so, you probably should. It is a cheap part. However, from my experience it is usually accompanied by an engine code.

[@stargazer8085]

No you do not always have the code with it. Symptoms of a bad cps are no start, slow start, or no start when car is hot

[@unfadeablecivic]

@@stargazer8085 It ended up being my fuel pump

[@Mau105]

Great tutorial for common problem. After getting the sensor and setting up the needed tools my T8 female Torx will not fit on the CPS bolt and the T10 is too big. So had friend get another T8 from auto parts store. Noticed that you are demonstrating removal of bolt turning ratchet clockwise. Is this backwards?

[@masood-tv]

Hi Dr. Paul, thank you. No, I think the wrenching sound is lagging in the video...it does turn left to open.

[@Theundisputedtruth]

Thanks mines say crankshaft circuit malfunction so probably a bad connection ? Instead of replacement ?

[@masood-tv]

Not necessarily...bug could be a damaged wire, etc...

[@Rhaspun]

I saw another video. The guy thought he had a crankshaft position sensor issue. It was actually a bad grounding cable.

[@abelramos5695]

thank you for sharing this video. I have a 1995 c220 I think is a w202 chassis. and sometimes run excellent and sometimes does not start or its running and the engine shuts off by itself. sometimes I disconnect the battery and starts again , sometimes nothing happens. only cranks.... is it possible this crankshaft sensor? thanks

[@masood-tv]

It could very well be...some of the symptoms you mention are the same...

[@somatra52]

Excellent video. Meek it coming 👍🏿👍🏿👍🏿👍🏿👍🏿🤟🏿

[@masood-tv]

Thanks, Somatra52.

[@passport619]

OMG I'm going crazy trying to get this sensor off! I can't reach in there well 😫😫

[@masood-tv]

I know...find someone with smaller hands to do it. But, you have to know where the bolt is first. For that, insert a cellphone in and take a video with phone light on.

[@passport619]

I was never able to get to it and a local shop wants 190$ cause he says he has to get a cess from under the car and remove a bracket first. Hope this does not fail soon 😫

[@emajou1691]

Great video bro 👍

[@masood-tv]

Thanks, Emad.

[@nomebear]

It's difficult to replace, especially if you might be a larger person. Buy a top brand replacement, because you don't want to replace it again.

[@masood-tv]

Good point. Thx.

[@teamyak4887]

Doesn’t matter the brand overtime it’ll go bad due to wear and tear so another big guy is going to have to do this again lol

[@Linkcel]

is it possible to make the replacement of the part for the bottom of the car or only on top if you have access to it?

[@masood-tv]

Hi Linkcel, I don't think there is a path to it from the bottom, if there is, it may not be as easy or easier to get to...

[@22hh2]

Can u help me I have samilar problem the car crank more than once but after that it works is it from crank sensor ??

[@masood-tv]

Hi Hassan, when was the last time you replaced your CPS? Most likely, yes. If the problem persists, it could be the Camshaft Position Sensor. That one is a little more expensive, and a lot easier to replace. But, it is a good idea to replace both at the same time if they haven't been for 70K miles or so. To determine the root cause precisely, scan your codes.

[@gbush1620]

My W210 got the same problem recently, I follow your video and make the replacement and it's resume normal now. Many thanks!! There's another (Front) crankshaft position right above the alternator (part # 0232103037 A0041536928), do you think we need to replace this too?

[@masood-tv]

Hi G Bush, na, the other is the camshaft position sensor - a little more expensive but longer lasting. Replace at 150K miles or 15 years.

[@kevinfernando3167]

G Bush what was your w210’s mileages when the crankshaft sensor went out?

[@gbush1620]

@@kevinfernando3167 It is about 157,000km = 97555 miles. Now this vehicle looks good, however… it will have once a few more seconds crank longer, intermittently say once, driving 10 times. I read Mercedes Forum, the Fuel pump, filter may need to be replaced. So, I ordered a new BOSCH fuel pump for the next project.

[@patioche]

Hi G Bush. Any recommendations for some mercedes forums. Thank you very much P.

[@boryanashakleva8046]

Quite a common issue for w210, often mistaken with fuel filter problem during the cold weather ( in some cases even bad diesel also) . Masood , thanks to your video i was able to replace the crankshaft sensor myself. I'm a woman, not easy to figure out how to do it without any help 😂🙈

[@joshuajackson9116]

I can use your help

[@LowAudio]

So I’m working on 06 clk but have stored code p0025 for continuous camshaft adjustment (left) incorrect position of exhaust camshaft, replaced camshaft position sensor, still cranked but no start. Currently replacing crankshaft position sensor, let me know if you have any tips for this.

[@LowAudio]

Also has fuel pressure, checked shrader valve on fuel rail and sprays with pressure out.

[@masood-tv]

@@LowAudio It is hard to tell from afar...it could be a timing issue also. You mentioned CLK...if it is a CLK350, then there is a camshaft magnet too that you may have to check...

[@fasteddie0318]

You probably figured it out, but that code means that your timing chain balancer gear is worn out and the engine has to come out to replace it

[@markenmarkus]

Hi, my w220 400cdi is sometimes cranking for a long time before it starts. This happens only when engine is hot. I also have codes P1372 and P0380. Do you think this could be the CPS? Thanks

[@masood-tv]

It is very possible, Markus. The part is not that expensive.

[@markenmarkus]

@@masood-tv I repaced all glow plugs (one was defective) and fuelfilter + a shitload of old faulty codes, car seems to be working fine now (Y)

[@masood-tv]

@@markenmarkus wonderful, thanks for the update

[@markenmarkus]

Update, the issue came back.. car suddently wont start when hot. I replaced the CPS, car still cranks for 5-6 seconds before starting. What else could be the issue?

[@masood-tv]

Hi Markus, it is hard to tell remotely. I would suspect fuel leak somewhere next.

[@mohamedfiraz7041]

Will the engine run without the sensor wire ?

[@masood-tv]

Hi Mohamed - No, it will not.

[@icebergtrails]

What a pain in the ass. Fixed my crank-no start issue though. No codes.

Great.

[@matt7iron]

Took me 2 days on my yr 2000 E55 screwing around and not knowing what I was doing to change mines, no help only KZbin videos, had to rub olive oil all over my hand and arm to slide down there, I somehow got it changed and it started right up, never gave me a warning before it quit in my driveway one morning, did you hear a little click when you installed the new one, I did, also no codes either.

I have a c280 crank no start........the engine stopped while driving. No check engine light/ No code/ crank No start. can someone help me.

[@masood-tv]

Hi Leo, it should throw a code. There are two sensors in this scenario that could go bad from my experience - crankshaft and camshaft position sensors - but both put out a code. Keep in mind you minimally need fuel, air, and spark for a successful start. So, you will need to do some troubleshooting with the fuel, air, and spark delivery mechanisms. Having said that, you can and should replace the CPM if it hasn't been replaced for a long time or ever. It is cheap and preventative if nothing else...
