I'm 90 percent certain I got my cam gears lined up properly. Did the set crank at tdc, using the mark on the left of the pump. Rotated cams 1/4 turn CW then back to marks on cover.

If it should be off a tooth would the CEL come on within a day or two? I put about 40 miles total on it per day.

Thanks.

the car would notices the first time it went in a full revolution on the engine.

Re: (firehawk618)

That code you be a 'two trip' code if it came on.
So it won't come on on the first start, it will log a pending code. Second trip it will set the the hard fault.

Re: If cam gear is off time how long till CEL? (firehawk618)

It is a little over 8 degrees per tooth (42 tooth gear), and twice that at the crank, (21 tooth).

If you are off that much, the CVVT can not deliver the advance/retard that the ECM requests, and you will get a CEL.

If you can get to someone with VIDA, that knows what they are doing, there is a Camshaft Quick Check routine that will check the static timing and also confirm that valves, hubs, solenoids of the CVVT are working properly.

If I use my scanner and look at the cams at idle anyone know how many degrees it should show?

EDIT* Eh, did one trip today, to work, 2nd one will be return home.

If no CEL i'll assume it's timed correctly.

wouldnt it noticed it every time you did a full revolution on the timming ?

 

[firehawk618]

Well, got 2+ trips and so far so good.

Thanks for the responses all.

Yes but some codes are A codes which are 1st trip faults and illuminate the CEL first trip. Others are classified B type and are 2 trip faults which see the same fault in two consecutive trips. I have seen where this type of issue or fault, only occurs on the second trip. Basically if the CVVT's or CAM gears were off a tooth or two, the car could be driven and was parked in the lot for pickup. This means the tech who replaced the belt never really drove it because if they did, they would notice the lack of power on acceleration. Upon the car being picked up, second trip, the CEL would come on and customer would be pissed.

The dealer I worked at had a guy that had this issue happen to him about once a month. He would argue it was always a bad CVVT and try and sell them after he had just replaced the timing belt. It really meant he F***ed it up but tried to cover it up.

I'm glad I'm gone from that Stealership

Yeah man, I work with guys who can't face up and make excuses make me sick. I'm sure we all know at least one.
