DnDEntertainmentOk: Nicely done. I saw where you were showing the difference in the OEM and the aftermarket Crank sensor. What did you do about the tab being on the opposite side of the sensor? Did all this actually fix the problem?
mvnjv1004: Mines does the same thing. I've already replaced my two sensors, now I'm replacing my throttle body. The idle gets really low when I'm at slow speeds or I stop such as at a stop sign/red light. Then it just dies. Will let you know how it works out once I replace the throttle.
amit kalsi: Did you get them from Nissan?
Jjuan1082: My nissan altima keeps dyng on stop singns sometimes when its running could this be the problem???answers please!!
jayvang33: Yeah the engine code problem is p0507. It definitely has a rough idle from time to time. I was told to clean the IACV but I don't know where it is. Is it attached to the throttle body? Or do I need to replace the whole throttle body unit?
ihittabusta: Dude, you're awesome. This will help me with my altima
Cee1987: I called nissan and they said they dont have such recall for this item? My car wont start at times, Do you think the sensors are the problem?
Navid Budhwani: i have a 2005 nissan altima and i had the same problem just last month. my car would not start sometimes, and hard starts the other times. got both sensors replaced and now it works better but occasionally i still have hard starts.
mvnjv1004: Yeah the SES light just came on for a few days and pointed to IAVC is where I'm lead to believe is the problem (P0507). It does struggle at times for example it will go up to 4K RPM and then struggle back and forth. At this point, I don't know what to fix anymore. Any ideas on what I should replace?
youngbull360: Hey this is a response to our convo. I now hav both crankshaft and camshaft changed and the the same 2 codes (p0725, p0335) still appear :( I'm lost
Emmanuel Roberts: Can you upload a video tutorial on how to tune up your nissan altima? I learned how to change the Camshaft & Crankshaft Position Sensors, so Im sure I can learn to change spark plugs. Thanks
2009VWJETTATDI: The issue was the same with the vehicle I worked on in the video, no DTC's were produced. The only reason I knew to replace the Crankshaft PS was because the usual mechanic had replaced the Camshaft PS & after a subsequent failure to start, suspected the Crankshaft, a Flex-Plate he called it, which required tearing down the tranny. I opted to replace the Crankshaft PS & I was spared. Maybe it's your Idle Air Control Valve? Does it run rough when accelerating (above idle)?
jayvang33: Great video. I had to do this back in the summer of 2010 and this would have saved me a lot of time. Anyways, my car has been randomly shutting off again. It's been over a year and I wonder if it's the same or a different problems. It has the same symptoms: idle struggles, shuts off when I'm at a stop, etc. I don't get any check engine lights though. I replaced the sensors with the Duralast brand just like the ones you got in this video. Any thoughts or maybe you can direct me to a site?
youngbull360: Ok great, im going to do it. I will let u knw how it turns out, Thank you soo much
2009VWJETTATDI: I can't remember where I read this, I believe that the code is produced when the Camshaft Position Sensor and/or Crankshaft Position Sensor circuits are at fault. Circuits meaning the Sensors themselves, the Computer, the Wiring in between them, all it takes is one flaw to fault. Chances are your Camshaft Position Sensor is bad. Speaking for myself, I would change it. Your engine should run better. You would need to clear your DTC's thereafter & see if DTC returns.
youngbull360: '06 altima. At first my car wud randomly shut off if traveling at low speeds or low rpm and wud kinda jerk into gear. I changed crankshaft and that problem erased but same p0335 code appears. Cud it b that camshaft is affecting codes? Pleas help!! I need emissions to pass!!!
2009VWJETTATDI: Sure thing, glad it helped!
2009VWJETTATDI: I appologize for the very late response. However, I have never attempted to mess with the timing chain, nor am I yet familiar with it. Sorry.
2009VWJETTATDI: Glad it helped! I actually did the procedure twice on the Crankshaft Position Sensor and I did it a heck of a lot faster than the 1st time around, which was actually the time in the video. I did it twice to see how much time it should take you to do this once familiar with the task.
TACOMAMUDDER: Great video,,, it really helped out alot... Really appreciate it....
xaral99: Thanks for the great video. It took me exacly 20 minutes to change the crankshaft sensor after watching your video. I knew exacly what to look for and to tell you the truth it really was not hard at all. the tip of inserting the screwdriver to push the green tab on the sensor allowed for the connector to be pulled off easily. I took it off from the top side and was able to slide my arm to reach the sensor. However all this would have been very frustrating without your great video. Thanks!!
Homelesskateboards: Thanks for the video!!
Ashleigh Segovia: How do you remove camshaft sprocket off without taking timing chain front cover completely off?
cllintot1: I have a 2003 3.5 and it is a lot different, but I can't get the plug to disconnect from the sensor. Help please. What is the trick?
Emily Choplin: I changed both sensors on my nissan Altima 2005. 3 months ago.
Now the car is beginning to have difficulties to start when hot.
Does the car's Comp has to be reprogrammed after installing the sensors?
Because I haven't done that.
Thanks in advance.
MasterChee7: maybe you can help, my check engine light came on on my 2005 nissan altima, i ran a diagnostic and the code was p2135 for the throttle position sensor, i then took my car to the nissan dealer because the car had a recall, they replaced my crank shaft sensor and the check engine light went off, two weeks later the light comes back on with the same code, p2135, does a bad crank shaft sensor affect the throttle position sensor, and should the dealer fix this for free???
TheTD1991: Thank you for the reply. My car runs great but when the car is in Drive and im holding the break petal down the car vibrates, but when i let go of the brakes the car is fine no vibrations at all.
2009VWJETTATDI: I hope it is the fix. Please post if it was a fix or not, for others. Thanks!
2009VWJETTATDI: Vibration can be caused by many things. The first thing one must do is "colorfully" describe the noise the vibration is causing. Open up the engine compartment and take a good listen while the engine is running. Listen from the inside of the cabin, doors closed, radio off, A/C off...then slowly increase RPM, see if the sound gets worse, goes away, or remains the same. Some people mention that the A/C has caused them vibration, others that the engine mounts have gone bad.
akirasrequiem: thank you very much, this has been VERY helpful. let's hope tomorrow I can do this...and that it was the problem! o_o
Michael Schofield: I thought the video was great it helped me out a lot... ignor this moron(s200eg)
tonydemko: Thanks for the video really helpfull. But i replaced the sensors with this video, but the car is still vibrating what might be the cause?
Krysis91: So I ended up going to the dealer and they said it was not a recall, maybe only on the 02-04 altimas it was. freakIN SUCKS 260$ down the drain....
2009VWJETTATDI: Hey, what happened to this comment? Bring it back! I wanna see what it said!
2009VWJETTATDI: Assuming that the Camshaft or Crankshaft Position Sensors are to blame I will tell you that your scenario is exactly what happened to the car in this video. The mechanic replaced the Camshaft Position Sensor (the easy one) and a few days later the car would not start. The bad Sensor, as I have read in other people's blogs, tends to be the Crankshaft Position Sensor (the more difficult one). For that reason, many people replace both sensors on the same visit.
44olguita: the mechanic changed the Camshaft Position Sensor and the next day I was driving the car and it shut off. can you give me some light in what is wrong?
2009VWJETTATDI: Thanks! :^)
D Flo: freak you video is so freaking annoying for some reason ...mayb cuz all you do is freaking point ...
Krysis91: thanks man you really helped me out!!!!!
2009VWJETTATDI: I have read different things from different people, that the sensors are indeed replaced by the recall, but also that they just reprogram the ECU to require only one input from any of the shaft sensors to operate the engine should one of them fail. I ran into this online, check it out _ttp_//maxima.theowensfamily.cQm/tsb/NTB03-124.pdf "The best thing for you to do is to contact a Nissan dealership that you would trust and ask them."
Krysis91: i have an 05 altima with the crankshaft position sensor broken/car is hard to start.......will nissan replace it for free?????
Nmalrdytkn: DUDE!!!! THANX!!! Wound up doin it from tha bottom. Shwew!' 2hrs!! But, I got it. Don't have those popeye spinach muscles.wifes car had been thrown all kinds of codes in the past month. No crank code tho, till yesterday. But my bro seemed to think that was it the whole time. It shifted hard once from 1st ta 2nd. Then today it didn't do it till she was runnin 65-70 mph. Hope that's it. We'll c tmrw.
2009VWJETTATDI: He is right, once you can figure out where the Connector is from the top, since you can't see it directly, it's best to work from above. This way you won't have to raise the car, as an added plus.
MsAhume: easy from the top
MsAhume: i have 2002 nissan altima i change both postion sensors and it still wont start i dont have any spark comeing from the plugs firstname.lastname@example.org
Nmalrdytkn: Is it easier foam top or bottom?
2009VWJETTATDI: UPDATE: The car has run just fine since the replacement of the Camshaft and Crankshaft sensors 60 days ago.
2009VWJETTATDI: If your starter is ground down, the sensors will not help you, even if they were bad to begin with. Sensors simply provide input to the ECU for engine operation. From what I have read, a bad sensor will only provide bad input (or none) to the ECU for engine start and operation. A bad sensor should not be the cause of your starter grinding down. I don't know what would be, but here is a link that I ran into: answers.yahoo dot com/question/index?qid=20101124210615AAJYTRi
