I have an 04 accent gl 1.6L DOHC. It has 122 000 km. Long story short. I went to get my timing belt and water pump replaced. Turned into a head gasket, timing belt, 2 intake valves, as well as all belts. So of course the cams had to be remove to torque down the head after the valves and head gasket were done. Now I know that the cam sprocket notch is set at 12 and the crank notch at 1. When the cams were put back on both sprocket attched by the timing chain were timed somehow,my buddy did it. Everthing was checked and started. Thought everything was good till it was started a second time. Got a check engine light, code P0340, cams sensor curcuit malfunction. Wire were check and sensor replaced. Still running P0340. I read that if the timing is off by a notch or two it won't cause problems by set off the code.



So I need to know how to time the intake and exhaust cams by the chain. I need a diagram and walkthrough. If the crank and cam by timing belt are exactly at 1 and 12. Were do the marks the two other sprocket get aligned? And does the intake cam rod only align with the sporckets one way?



Thanks



Having a hard time finding info and my cars sucking by the gas with little power and misfires.

 

Sounds like you may have gotten the exhaust cam and intake cam in backwards the intake cam has the pickup for the CPS. Here is the link to all your answers just create a user account and have fun --->Webtech

 

I already created an account there but they don't list how to time the cam chain and two sprockets. Sorry the cams were put in right. I just got it backwards. The intake does have the cps. If the notches are suppost to be positioned opposite each other then the intake is off by 1 maybe 2.

 

I will look at my shop manual and respond. If you don't get an answer by tomorrow send me a PM to remind me. It has a bit more info than webtech on some things.



I'm sorry, I'm not clear. Does the car run or will it not start? If it runs, does it appear to run well or does it have issues? If the cam position sensor fails the car won't start.

 

My car starts after 5 maybe a few more cranks. It misfires. It runs a little rough. Has little power (engine revs if you push on the gas and doesn't go fast) the exhuast smells rich and the check engine lights on with code P0340. I replaced the cam sensor and have been reading if the timing off by a tooth or 2 it could through the sensor. Wants to stall every now and then. I had the rocker cover off 2 days ago and think the intake cam was 2 teeth off the exhuast cam. No interference with the pistoland valves so far. Didn't want to touch the timing till I knew for sure. Could cause my problem? And extra gas usage?



Thanks. I believe I just need the timing from cam to cam. The cam sporcket is set at 12 and the crank at 1 or 3, my buddy did it. Right so far? And the 2 cam shafts are suppose to be 3 and 9?

 

I would be inclined to suspect the sensor or wiring. I know you replaced the sensor, but possibly the connector, a ground used by the sensor, etc. could be faulty. I will double check cam chain timing from my manual, and if it'll help I'll pull my cam cover off my spare 1.6l and check it or get a picture for you.



Also, since you were doing all that work, double check that all engine to chassis grounds are reconnected and solid. Bad grounds cause all sorts of problems.

 

Thanks so much for your time. I am pretty sure that it is not a wiring problem, as the sensor and wires were never touched. Just layed over to the side. How easy is it to check the circuit with a volt meter. I got one that can check up to 500 w but never used it before and dont want to fry anything. I am hoping to get it fix (Hopfully) by tomorrow.

 

Sorry, I pulled out the manual but got distracted last night. I'll try to remember when I get home.



It'll be kind of a PITA, but you could check the resistance of the wires from sensor to ECU. That would let you rule out a wiring issue.

 

Sounds difficult. I'm a quick learner about most things electronic or mechanical. But for now don't know how or were to put volt meter or where to put the watt knob to test that,or if the car should be turned on or battery unplugged.

 

Here's the diagram. Sorry for the delay.



As far as using a multimeter, I bet there are DIY's online. You will want to measure the resistance with an Ohmmeter, or a multimeter capable of that function.







Exhaust cam timing chain mark should be at 9 o'clock between 2 links, intake at 3 o'clock in the center of a link.



Crank sprocket timing mark should be aligned with the mark on the oil pump. This should put cyl #1 at TDC. The mark is at about 1 0'clock. The crankshaft keyway should be at 3 o'clock. I put a dowel through the spark plug hole to verify that I was at TDC.



Cam belt sprocket should be aligned with the timing mark at 12 o'clock.
