Toyota Repair Problems? Ask a Mechanic for Answers ASAP
Thank you for using Just Answer for your needs. Did you go back and recheck the timing belt marks?
I think I did lined up the dot (hole) found in the crankshaft sprocket with the small nipple on the engine housing and the mark on the belt seemed to be not right. Well, I'll check it again.
( Does the arrow in the belt supposed to be aligned with that small hole in the crankshaft pully?)
Thanks! yes and it worked. I found out that there are two marks. one in the crankshaft sprocket and there's another in the thin sprocket that is behind the crankshaft sprocket. Also first I lined up the crankshaft pully mark to the number zero in the plastic timing belt cover.
There seemed to be a slight tik tik tik sound in the engine ( sometimes hardly notice) could this be a problem in the long run for the engine? Also the check engine light is still there. what could be the reason?
I doubt the noise will be a problem and as for the check engine light, did you clear the computers memory or clear the codes by disconnecting the battery?
while I was working on the timing belt I disconnected the negative from the battery. Please explain the process of disconnecting the battery in order to clear the codes or the computer memory.
To clear the codes you can use a scantool or the local auto parts store will do it for you. You can also disconnect the battery for 3-4 minutes.
Just one side.
it worked but not for long. When I disconnect the battery for few minutes then connect it again the check engine was gone but after a while the light came back. What could be the reason?
We need to check the computer and see what code is stored. Check and let me know.
Sorry I could not come back to you earlier as i've been very busy with other works but a friend check the code with a code reader and he mentioned that it's showing about the crankshaft. I don't know exactly what the code number is but I told him to let me know may be tomorrow or after.
So sorry, still couldn't get code reading yet. Been so busy at work. I was wondering if it could just be a bad 'crankshaft position sensor' that caused the the check engine light to be on and the reader showing about the crankshaft.
Where the crankshaft position sensor located? Any way I am trying to get the reading asap and will let you know.
It could be a crankshaft sensor but I think it was more to due with the timing belt issue and yes, we would need the code to be sure. The crankshaft sensor is located at the bottom pulley (the crankshaft) near the harmonic balancer.
Hi again, finally i could have the reading done. Here's it, P0016 and P0018 it says - crankshaft position - camshaft position correlation - bank 1 Sensor A. Please let me know your advice onn this.
DTC P0016 CRANKSHAFT POSITION -CAMSHAFT
POSITION CORRELATION (BANK 1 SENSOR
DTC P0018 CRANKSHAFT POSITION - CAMSHAFT
POSITION CORRELATION (BANK 2 SENSOR
Refer to DTC P0335 and P0339 on page 05-113.
DTC No. DTC Detection Condition Trouble Area
Deviation in crankshaft position sensor signal and VVT sensor
1 signal (2 trip detection logic) Mechanical system (Jumping teeth of timing belt, belt
2 signal (2 trip detection logic)
Read freeze frame data using the hand-held tester or the OBD II scan tool, as freeze frame data records
the engine conditions when a malfunction is detected. When troubleshooting, it is useful for determining
whether the vehicle was running or stopped, the engine was warmed up or not, the air-fuel ratio was lean
or rich, etc. at the time of the malfunction.
1 CHECK VALVE TIMING (CHECK FOR LOOSE AND JUMPING TEETH OF TIMING
BELT) (See page 14-84)
NG ADJUST VALVE TIMING (See page 14-84)
The problem is that the timing is not on correctly. I shall send the proper procedure. Also make sure that the belt that you got is for the 3mz 3.3 and not the 1mz 3.0 engine

NOTICE: If the timing belt is disengaged, having the crankshaft pulley at the wrong angle can cause the piston head and valve head to come into contact with each other when you remove the camshaft timing pulley and camshaft, causing damage. So always set the crankshaft pulley at the correct angle.
NOTICE: Do not install the tensioner as it removed.
NOTICE: To prevent contacting the piston head and the valve head, set the crankshaft pulley at 60° BTDC/compression position.
Ok, finally after reopenning and resetting the timing belt I think I got it right and the check light went off and running well. But shortly after that the car won't start at times not even a click when starting it but battery is ok. Sometimes all of a sudden would start but right now it won't. I got the code reading done and here are the codes - P0353 - Toyota manual says' ingnition coil "C" (or #3) primary or seconday circuit malfunction and P0356 is "F" (or #6).
Which one is C and F and how do I proceed with this thing?
Hi it sounds like you have two bad coils. Number 3 which is located in rear of vehicle next to fire wall. Number 6 which is in front of engine next to radiator. I would first remove number 6 coil and swap it with number 1 next to timing belt. number 6 is next to transmission. then reset check engine light and see if the code reads number 1 (P0351). Then if does change i would get to rear one change spark plugs and number 3 coil (in the middle)and put back. Then test drive. If the first step doesn't work swaping coils you need to check compression and spark plugs, Good luck let me now.
