In this video I show the method I use to get the proper air gap on a GM crank sensor. It's an old trick my grandmother taught me and is a pretty fast method to use to make sure you are setting it to the proper limit. -Enjoy!

  1. Avataaar/Circle Created with python_avatars carcass cruncher says:

    So if the space between the reluctor wheel and the sensor arent within speck will that cause a no spark?

    I had same code, changed the crank shaft sensor and wasnt getting spark. It didnt come with and shims either.

    Thanks man.

  2. Avataaar/Circle Created with python_avatars Jess Atwood says:

    Thank you very much well explained appreciate it have a wonderful day.

  3. Avataaar/Circle Created with python_avatars R Taggs says:

    Took son's truck sensor out and sure enough the ASE mechanic that rebuilt the engine did not shim the sensor, it had a gouge and scratch marks on it.

  4. Avataaar/Circle Created with python_avatars Kelli Smith says:

    0.030 is minimum for the air gap I wonder what the maximum is, where do you get those spacers I can’t seem to locate any, I will look for a suitable washer. So if the face of the sensor is gouged from contacting the exciter wheel does that mean main bearing slop, or would a wearing timing chain cause this ?

    HI I HAVE A 2009 CHEVY IMPALA 3500 V6 NO POWER RUFF START NO RPM CODE CAME UP P0335

  6. Avataaar/Circle Created with python_avatars Joel Saenz says:

    Helps me out. But aren’t those called calipers?

  7. Avataaar/Circle Created with python_avatars Reggie Baker says:

    Great tip about the air gap! I used play dough and measured. I had to use both shims to get the proper air gap. Truck started right up and my oil leak is gone! I also dropped the connector gasket and put it back on to the connector and had to repair the wires with liquid tape. Thanks for the video!

  8. Avataaar/Circle Created with python_avatars Jimmi Wilson says:

    Go back to ge connector!!! I've been all over youtube. My connector on my 03 express had one of the wires completely hanging out. The only replacement connector I could find anywhere has all three wires white. Whoever designed it is an ass. I looked at the connector I cut off and the wires that are hanging and from the years of fading I cant really tell which go where but I'm pretty sure I just saw a purple wire in your background. Which wires for where?!? Who the hell makes an all white freaking connector???

    It's an old trick my grandmother taught me.
    I read that in the description of the video and just had to see what that funny line was about.
    Great tips like this takes the guess-work out of the repair job. Thank you South Main Auto Repair.

  10. Avataaar/Circle Created with python_avatars Eric Richardson says:

    Had the exact thing happen to my 2011 Nissan Versa. Took my mechanic a few tries but it finally threw a code for him. If it wasn't for the code, it might have been parts cannon time and he didn't want to do that.

  11. Avataaar/Circle Created with python_avatars 667 says:

    Hello. I want to clean my position sensor on my 1999 Blazer 4.3l V6 AWD, because it is full of oil… When i pull it out and back in, is then a relearning nessecarry? Or only when i change it with a new one? Thanks!

  12. Avataaar/Circle Created with python_avatars Johnny Estrada says:

    dumb video waste of time

  13. Avataaar/Circle Created with python_avatars Brittany Bradford says:

    I have a 1995 chevy truck 1500 5.7 I was told i don't have one

  14. Avataaar/Circle Created with python_avatars Panther Platform says:

    Fascinating. I'm working on a 2000 gmc sienna with an intermittent misfire. I'm going to try that relearn procedure.

  15. Avataaar/Circle Created with python_avatars Mother Fucker says:

    It would be a great help if you put the make and model of the car you are working on in the title of the video, otherwise it's MEANINGLESS!!!

  16. Avataaar/Circle Created with python_avatars Valerie Rodriguez says:

    How do I get a hold of you

  17. Avataaar/Circle Created with python_avatars Who Zaskin says:

    Thousandths????? Gee, must be a very well made sensor, and the ECU must have excellent capacitor buffering. Honestly, 70 year old cars had accurate tachometers. I get it takes a lil more precision to get a nice square wave, but wow. Hideous engineering. Thankfully Eric is here with the tips.

  18. Avataaar/Circle Created with python_avatars my1after909 says:

    Hi, Great tip! I just bought a sensor from A1, but am concerned, that the sensor is not held snugly in the retaining plate. I haven't installed it yet, but wonder if that play is 'not a concern' . The part is from Taiwan. Thanks for your great channel!

  19. Avataaar/Circle Created with python_avatars Danny McNeal says:

    This was a great video! I’ve been watching a bunch of YouTube videos to learn how to replace the Crankshaft Position Sensor after my OBDII scan tool showed a P0338 code on my 2000 ZR2. But then I thought, “How do I know if I need a shim? And how do I measure that distance?” Brilliant technique!! And I have a nice micrometer. Thanks a million!! PS: Do I need to do some kind of driving re-learn sequence to get the Blazer to properly use the new sensor? Thanks again!

  20. Avataaar/Circle Created with python_avatars juan marshall says:

    Is it possible that the crank position sensor can be going bad without a code because I have replace all ignition parts as well as the fuel pump and I still get a cut off and most of the times it starts back up sometimes it's don't?

  21. Avataaar/Circle Created with python_avatars onefixitman says:

    Thank you. I am trouble shooting a crank position sensor today on a 4.3L.

  22. Avataaar/Circle Created with python_avatars Modus Operandi Studios says:

    what if you are over .030?

  23. Avataaar/Circle Created with python_avatars Allen Harrell says:

    what is the next step if and new sensor gapped correctly does not fix the problem I still get the PO335 fault

  24. Avataaar/Circle Created with python_avatars christian says:

    Had a similar issue with my 13' outback 3.6. Subaru has a shim kit but they want you to pay for it. Pretty ridiculous. They build a flaw into their vehicles but expect their customers to pick up the tab. The ultimate insult is that the kit is absurdly expensive. 60 bucks for a few gloried washers.

  25. Avataaar/Circle Created with python_avatars Real Spiit says:

    I need some shims for my 5.7L LT1. Anybody know where to get them?

  26. Avataaar/Circle Created with python_avatars Bryan Fields says:

    I have. 98 Silverado 5.7l. New distributor. Crank sensor plugs wires and pcm. Keeps frying coil packs and icms. Had it in a shop and they adjusted timing. But didn't fix the issue. Showing cam crank correlation code. And crank sensor variation not learned. Any help is appreciated

  27. Avataaar/Circle Created with python_avatars Stephen Grant says:

    Miked mine on my 99 burb 5.7 and the closest i could get was with 2 x 3/4 inch copper compression gaskets that are .062 thick, same sensor

  28. Avataaar/Circle Created with python_avatars Stephen Grant says:

    Never seen a shim with a sensor but that was all my problems except for the loose coil causing high primary volts. If not a ACDelco part, GET TWO lol Non GM parts are cheap becuse they didnt pass speck

  29. Avataaar/Circle Created with python_avatars Dave Herrera says:

    Thanks for being thorough. Great video

  30. Avataaar/Circle Created with python_avatars Stephen Grant says:

    Yeah, gonna have to go find shims. silicone isnt working out

  31. Avataaar/Circle Created with python_avatars micro61micro says:

    wow totally smart cool thanks

  32. Avataaar/Circle Created with python_avatars Patrick Mansfield says:

    Sort of related. Can't find either a crank or cam sensor at O'Reilly's? Doesn't show on their web site for a 1994 Chevy Silverado K1500 V8 5.7 4×4? Could it not have either?

  33. Avataaar/Circle Created with python_avatars oldtimedrumcorps says:

    Dont you need to allow for the o ring? The o ring will keep it from inserting all the way . we are talking thousanths right ? what say you?

  34. Avataaar/Circle Created with python_avatars LightningSurvivor 14 says:

    It wasnt until my truck started shuttering that i was questioned if my sensor had shims or not. The previous owner did not have shims so when i ordered a new crank sensor i just pulled it out and put the new one. It started shuttering so i changed out the fuel filter, fuel pump, fuel lines, plugs, wires, distributor and just went ahead and put a new timing chain while i was at it. What a waste of time after watching this video come to find out some sensors dont come with shims, so they were put on and wham, it runs now. SMDH.

  35. Avataaar/Circle Created with python_avatars Mr. Smith says:

    the piece I have must have broke in the hole.. The one that came out is smaller then the replacement? Do they seperate? Or do I grab whats in there and pull on it? It looks like the piece in there is metal? Nobody can answer this yet..

  36. Avataaar/Circle Created with python_avatars Erik Johnson says:

    As a DIYer this is like a huge revelation to me hahahaha!!!! AWESOME. I learn so much on this channel. I had a dream last night that you hired me as an apprentice…a 49 year old drummer working at SMA…your worst nightmare lol

  37. Avataaar/Circle Created with python_avatars Lorenzo Elliott says:

    will that Cooper print spacer stop fire to your wires

  38. Avataaar/Circle Created with python_avatars westernlover33 says:

    I removed both rocker arms from both heads.. without marking where they came from.. did I fick up

  39. Avataaar/Circle Created with python_avatars john argue says:

    Me gusta!

  40. Avataaar/Circle Created with python_avatars Brandon Crocker says:

    A side note to anyone that cares. I was getting a p0300 code on my 2002 chevy silverado. Took it to 3 mechanics, couldn't solve it. I replaced my crank sensor after researching as much as possible. Wasn't throwing a crank code at all. Fixed my p0300. Finally a mechanic says it! Thanks Mr. O!

  41. Avataaar/Circle Created with python_avatars Drew papke says:

    I have the same problem in my crysler town and country 2010 and just noticed 2 lines in the sensor is this why they want the shim done

  42. Avataaar/Circle Created with python_avatars Joe Burttschell says:

    Can the o-ring leak oil on the starter if its old, worn,etc ?

  43. Avataaar/Circle Created with python_avatars joe estes says:

    This exact thing happened to me, so this video helped me out tremendously! Thanks!

  44. Avataaar/Circle Created with python_avatars Kenneth Pauli says:

    I'm working on 08 and im like sma I hope there is a video! Stalled only when hot…212 at idle sitting g at idle for 10 seconds or more maybe 20…30 lol it dies for sure after time…hot.

  45. Avataaar/Circle Created with python_avatars yazoomud88 says:

    I'm doing this same job on my 99 Tahoe with a 5.7 vortec do I have to have some relearn procedure done after installing the new sensor?

  46. Avataaar/Circle Created with python_avatars Lo Paka says:

    Maybe I could do if you can do it, had I been down the same road as you, but I haven't.

  47. Avataaar/Circle Created with python_avatars WIZARDWERX says:

    THANKS for the tip

  48. Avataaar/Circle Created with python_avatars joe zolderdo says:

    Great video. I am in the same exact scenario. I was wondering if you could relay the pinouts with color codes. Only the center yellow wire is connected the other two are detached. The replacement part by BWD has all white wires (ABC) and no schematic. Supplier was no help.
    Thank-you again for the great videos.

  49. Avataaar/Circle Created with python_avatars Rico , suave says:

    I got a 1999 chevy Tracker with the same error P0335 , and i pull out the crankshaft sensor , it measure 612 Ohms , and i also checked voltage and couldn't
    find any voltage . any suggestions what it could be ???? Help !!! Please !!!!!!
