  1. Looks easy. My car just turned off and not running. Everything is good the only thing is the cps going to replace it this weekend. Very good video.

  2. Is there a difference in this particular tasking between the models of civics in the year category (EX, LX, DX, etc)? I hear the EX model is much more difficult. And the "Special Holding Tool", do I have to get this from a Honda Dealer…what do I ask for? Does 1AAuto have a "Camshaft Position Sensor" replacement video for the 2003 Honda Civic EX?

  3. After rainy days what causes the civic motor to idle violently while at idle as if it wants to shut down and eventually does? This has been happening to me after hard rainy days.

  4. If you don't have that special tool, any other idea how to hold it? Can the flywheel be locked or something?

  5. Just got mine replaced and this video was great for reference just makes it seem way easier than it was for my car lol! Thank you!!!

  6. My Honda Accord 2002 is giving me a code p1362 , I want to fix it myself but I'm not sure if I'm in the right track , I been told there's two TDC sensors one behind the timing belt and another one in the distributor, how do I find out for sure? Thanks for the advice!!

  7. Hi i have replaced both cam shaft and crank shaft sensor with pattern parts after fitting the car worked perfect for 2-3 weeks now the car is cutting out while driving and idling with the engine light coming up as cam sensor do you have any ideas?

  8. i have a question i changed the connector and sensor and know my car wont start. i check if there is spark in the spark plugs and there is. what could be issue????

  9. I have a 2004 Honda Civic Si coupe would it be the same place or different due to it being a si ?

  10. 2-3 hours of work to switch out the actual part that takes all of 2 minutes lol. Oh well, that’s vehicles for ya

  11. Is the crank shaft sensor the same as the camshaft sensor? I saw a video from scotty kilmer and he didn't have to do all that work to switch it. I might be wrong maybe the crankshaft is below the camshaft.

  12. Shouldn't I make sure engine is in time before removing that crank bolt/harmonic balancer? Please let me know if so.

  13. i have a 1997 honda civic dx, so i only have to remove the alternator belt and the crank pulley and the cover, to replace my crankshaft position sensor?

    "i dont have powersteering"

  14. Hello been trying to get this project completed but am having difficulty because my crankshaft and camshaft are not aligned. when i have the camshaft on up and have the two sides aligned, I don't see any marks on crankshaft. Also wanted to know the shipping time for parts to Oregon. subscribed and thanks. I recently did a valve cover and other repairs to the car and then everything started up but after couple of day…it would just die when idling and won't accelerate even if i floor it. Check engine code came with crankshaft position sensor but I had not even touched that part. Timing belt was never removed. Later it was even worse, it wont even start, starts with jump but then dies idling after a while and then have to jump again. I did clean out the EGR with brake fluid, don't know if that does any thing. Please help 2002 honda civic vtec ex

  15. sorry I am new to working on cars so please forgive if my question is stupid. When trying to remove the crankshaft bolt I accidentally rotated it clockwise just a little bit, hope that doesn't do permanent damage
