Camshaft Position Sensor Replacement

Here is a quick post on replacing the camshaft sensor.

1. Disconnect the negative battery cable.



2. Locate the camshaft position sensor, it is on the passenger side in the front on the block.



3. Remove 10mm bolt and remove camshaft sensor.



4. Unplug sensor, apply dielectric grease to new sensor and plug in, apply a small amount of grease to o-ring, replace into block and tighten bolt. Can't remember torque spec but will update it when I find it back.
5. Reconnect battery cable.

whew.. its not as easy as it looks.. purchased a camshaft from Engine Power parts and tried to install it via DIY. Took me 2 hrs but i was able to do it and am happy i did it. thanks.
a camshaft and a camshaft sensor are different items... we are talking about a sensor on this thread...

it should only take about 5 mins to replace the sensor....

to do a camshaft should take a few hours...

wanted to start a new thread on this but I figured I'd ask here first. I actually changed my camshaft position sensor about a year ago. when I did it, I accidentally crossthreaded the bolt that goes into the block. It was only partially screwed down though, and I backed it out and put it back in straight, I think.

either way, I just thought about it now and decided to ask. is this going to be an issue later on? am I going to be needing to replace that thing again any time soon? I don't think it was bad the first time, I just replaced it because it was relatively cheap and I had an intermittent starting issue. aren't the blocks iron? how in the world was I able to partially strip the threads? or was I mistaken and I partially stripped the threads on the bolt?

If its in and tight I would let sleeping dogs lie. If you do have to change it again just be careful when threading it back in. Maybe chase the threads first to clean them up with a tap.

Did this this morning as I was getting the long crank to start 3-4 times a day taking 3-4 times to start. Took about 8 min to do. Time will tell if it was the fix. But I did notice that for the first time in 96,000mi my car idles smooth now. Like Lexus smooth.

Ok, retard question time regarding number 4.

4. Unplug sensor, apply dielectric grease to new sensor and plug in, apply a small amount of grease to o-ring, replace into block and tighten bolt. Can't remember torque spec but will update it when I find it back.

Where exactly on the sensor do I apply it too? Obviously, it is the part that goes into the block, but the whole thing? Also, do I use the same dielectric grease on the o-ring? Do I remove it and grease, or grease while it is in?

Thanks for the help. I have gotten this long cranking start for too long and I'm going to give this a try.

I believe he meant to apply the grease to the terminals. Then apply a light amount to the OD of the Oring with it installed on the sensor. No need to coat the entire sensor.

I did not do any of this and it has been ok sofar.

I was getting a ruff idle with vibration. I change the cam sensor and noticeable smoother idle. before the change if i stop too fast the car felt like it wanted to stall not anymore. hopefully this may help someone with similar issues.

I've had that exact same thing happen to me and on two ocassions it actually stalled.
I thought it was bad gas or something.
Maybe I will try replacing the sensor.
I just dont want any codes or something

What are the symptoms indicating that the sensor needs changing? rough idle, codes? ___?
How much $ was the sensor?
 
#18 ·
I had intermittent long starts, surging @ part throttle and horrible gas mileage...
$36.00 OEM part from dealer. So far all is good........

this is something new to me i have just never heard of these sensors going bad on any cars that often especially in cars that are fairly new

Just went to do mine and the plug was different. Looked around online and they all seem to be the same as the one I purchased, but my cars plug is smaller. Anyone run into this before?
