Gofast Ok I got it while I was turning the crank I noticed the tensioner was moving I didn't buy a new one because it looked pretty new. I think it was loosening up while it was running causing it to get out of time. So I'm going to buy a new one on Friday and install it hopefully that's all it needs.

flflash ^^ Very good explanation of how to do it and yes the 2.4 is a pain.
06-04-2013 03:46 PM
RUBI 4 MY MRS OK, do you have the FSM? I have the ’05 & I think they are the same but the page #s may be off so tell me if yours match. The most important thing is to get the bottom marks lined up as in the fig. 98 on page 9-59. Then the intake cam mark has to be in line with both sprocket bolts shown in fig. 101 on the next page. You can see the straight line in that fig. All of the slack has to be out of the belt from the bottom to the intake cam. Sometimes it is easier to back the intake cam off a little to get the belt into the groves but then turn the cam to get the slack out & make sure the bottom marks are still on & the intake cam mark is lined up. Now in that same fig. 101 you can see that the exhaust cam is backed off slightly (½ tooth). That is to get the belt into the groves like I suggested for the other cam. With the belt in the groves you can turn the exhaust cam enough to remove any slack between the 2 cams as shown in fig 102. That should make both cams line up. Go on to tension the belt as described in the manual. That should leave everything lines up & when you rotate the crank 2 revolutions it should have the cam marks straight across when the bottom marks are lined up as in fig. 104.

Gofast Are the cams supposed to line up in a straight line? When I put the straight edge up to them they are a little off and there's no way to get them closer. When I put the straight edge up to the picture of the cams in the manual they are the same distance off. Does this mean its set?
06-02-2013 06:02 PM
Gofast Still working on it. Having a little trouble getting it set.
06-02-2013 05:15 PM
RUBI 4 MY MRS So is it reset & no codes?
06-02-2013 03:19 PM
Gofast Timing off half a tooth never thought of the straight edge trick really helped
06-02-2013 01:18 PM
RUBI 4 MY MRS Use a straight edge across the cam sprockets if needed. I'm betting the exhaust cam is 1 tooth too far counter clockwise from where it should be. Don't turn the engine looking at the cam marks, use the crank marks to TDC. Then see where the cam marks are.
06-02-2013 12:53 PM
Gofast Thank you I'm going to try and give it one last shot with setting the timing.
06-02-2013 12:40 AM
Slater451 They retimed it. It was a tooth off i guess. But as far as I know that's all they did. No sensors or anything like that.
06-01-2013 12:32 PM
Gofast Do you recall what the dealership did?
06-01-2013 12:14 PM
Slater451 I finally got my fixed after trying it my self. I ended up at the dealership.... They chared like 200 or so maybe a bit less. It wasn't too bad But just because the 2.4L is do finicky It was worth it!
06-01-2013 11:39 AM
Gofast Ok I double checked everything. The other codes i had went away still stuck with p0016 showing up. Any ideas on what it would cost to have a shop fix the problem?
05-31-2013 10:18 PM
Gofast I set the spacing for the cam sensor. I will recheck the timing and try to reset the cel in the morning and let you know what happens.
05-31-2013 09:53 PM
RUBI 4 MY MRS Did you set the sensor clearance to 0.030”? I don’t think that should affect the sync but be sure it is set. The rev limit of about 3000 is the engine going into “limp home” mode. If you reset the CEL & let the engine cool down completely then start it & let it idle more than likely the CEL will return at about 160º (& setting the limp mode).

You might have to put a straight edge across the center of the cam sprocket bolts to make sure the marks line up & be sure the TDC marks line up on the bottom gear. If you don’t back the exhaust cam off ½ notch before setting the belt it is very easy to have the cam one tooth off when you tension the belt.

Yes replaced the belt also replaced the camshaft sensor. Everything I clear the code with the computer and drive it, it hits 3000 Rpms light cuts bake on same code. The marks on the came an crank are dead on by eye. Do you know of another way to check it other then eye sight? I was also worried about valve damage but it runs fine until that code comes up.

Did the check engine light still come on when you hit the rev limiter at 3200 Rpms. I'm having the same problem on my 06 and the only code I get is camshaft crankshaft missalignment. This is keeping me from getting it inspected would greatly appreciate some help.

Follow the procedure in the service manual. Everything you need to know is there.

Slater451 If its the 2.4. Take it to a good shop you trust or the dealer. It's gonna cost ya a couple hundred bucks but it will be done right. I tried to do mine my self and it was a nightmare trust me just have it done professionally !

Dextreme I heard this is a better time machine if you don't have a Flux capacitor:

Do you have a set up to produce the 121 jigawatts needed to power the flux capacitor.
