Default timing belt reference lines

i put a new timing belt on my car and had all the pulleys lined up as in the meaty timing belt thread. when i turned the crank by hand i did one complete revolution of the belt. when it came back up the lines on the belt did not line back up with the marks on the pulleys. i notice though when turning by hand the lines on the pulleys themselves line up.

should the lines on the belt line back up on the lines of the pulleys or do they get mixed up after rotating??

i have also changed the cam position sensor.

after i started it i scanned it again and the cam position sensor code came up and p-0113 Intake air temperature sensor circuit high input

All the lines and the crank pulley have to line up again after one complete revolution. Also the cam position sensor might need adjustment or a learn pattern

i replaced the cam sensor 2 days ago and finally put the belt on today. does the crank pulley have to be at a certain stroke of the engine when lining up all the gears? and what is a learn pattern?? does that mean reset the computer ie: battery disconnect?

I have the same problem. I have been working on my timing belt install. Everything was perfectly aligned. It was checked many times. When I turn the crank by hand 1 full revolution, the lines on the belt do not realign themselves with the lines on the cams. However, the cams and crank are all lined up to eachother. I did not change the cam position sensor.
Also, I believe this is normal: When I turn the crank by hand, it is hard at points and then easy at others. I believe this is simply the revolution of the pistons and the cams moving as well. Am I correct in this? Or is something all messed up.
Please help with this. Im in the middle of the install and do not want to move on until I get a solid answer.
Thank you. -Bill

It takes quite a few turns to get the lines to get the actual timing belt marks to line up again. Just MAKE SURE each notch on the rear timing belt cover lines up with each single notch on the pulleys... and that the double notch marks line up with one another on the pulleys themselves.. of course don't forget the notch on the crank gear lining up too. If all the marks line up, don't worry about the marks on the belt itself. I would also recommend an ecu reset after replacing any sensors. I just pull off the negative terminal, hold the brake for a few seconds, and when your odometer display goes out, it's reset

Edit: yes, it's normal for it to get stiff, then easy when rotating the crank by hand. It's actually a good thing...it means you're getting compression, which also says you just might have everything lined up right too
