quick question

ok, so i went ahead and decided to pull codes from my car this weekend and ive got a question. when you pull codes its between the TEN and GND connection right? and when you turn the ignition on to view the codes i dont have any lights flashing. Im presuming that if i had codes to pull the check engine light would flash a code but mine would stay lit for maybe 3 seconds and then turn off.

so i guess my question is that if i have no light or flashing light does that mean i have no codes?

Greetings... been lurking for a while but I;'ve read enough to know that if the CEL stays lit for 3 seconds and then goes out while you are trying to pull codes you have no stored codes.

Congrats!

thats good news. But if my timing was off and the ECU compensated for it, would it show up in the codes?

Why do you think the timing was off? Did you check it with a timing light? The ECU will compensate as best it can if it is WAY off, but it depends on how badly it is off and how the timing got off track.

i dont know how much its off or even if it is off. i got the car used and it seems as though its ticking. Dunno but what ive been hearing it could be worn HLA's or timing out of specs. I dont have a timing light so i cant really figure it out.

Is the ticking coming from the valve cover or the timing belt cover?

Put in your profile where you are from. The MX community is pretty tight so maybe someone close could meet you and show you some things about the car.

How's the oil level on the dipstick? You recently got the car? You may want to do an oil change just for maintenance purposes. If the oil level is low, you may have louder valvetrain ticking than if it's up, so that's one thing to check.
Also, if you're hearing the ticking from the timing belt cover, the likely cause is the hydraulic arm that applies pressure to the timing belt tensioner.

ive done an oil change and ive put mybe like 5 klm on it. i put the good synthetic stuff into it as well.

How can i check the tensioner for the timing belt? Do i just push on the belt?
