Head gasket replaced, shed timing in sprockets, after numerous tries, have actually TDC rightchain yellow clues aligned each camshaft okay, follow to diagram. View no marks in cover other than drill note on sheathe exhaust cam, near 10 mm bolt.Intake cam mark in ~ 9 o'clock.Have compression 130 approximately. Turned engine on, no lucky removed and grounded spark plug no fire!Plugged scanner and shows video camer sensor failure and air fuel metering problem.
mirrors code P1111 and also P0340. Automobile was to run fine simply for burn exhaust valve (replaced).My concern still is, proper means to align cams? had actually TDC and the 2 yellow clues in chain to adjustment marks in sprockets however after turns by hand, will certainly not enhance again.Is firing mark number one in slot that intake electronic came is to be precisely aligned through sensor.Please it is in as detailed as girlfriend can. I am really frustrated and also my boy wants car out!
time chain point out 26 links in between gold/yellow mark on chain and 64 links in between camshaft sprocket and also gold/yellow link and crankshaft sprocket orange/blue link on the time chain next without the tension-er. View diagrams.Were password present before head removal? and also injector pulse?
as I explained earlier, there to be no codes engine was to run but missing on cylinder three, valves to be changed.Now password again 1111 and 0340.I watched diagrams before and installed chain according to diagrams. Number one cylinder TDC yellow marks on top and also sprocket point out on each yellow mark.Any other suggestions? Is that possible, no fire because camshaft no in place with spark sensor?
P0340 error in camshaft place sensor either open up or shorted or out of phase situated on rear head is it plugged in wiring intact?P1111 error Intake valve timing control either defective or open up or shorted IVTC has to be removed throughout repair have to not be disassembled. Is solenoid linked wiring intact?
Got vehicle started after turning engine by hand several times and matching yellow mark in chain and also sprockets, this is what i did;number one cylinder TDC to adjust with note bottom cover and also two yellow marks on peak of chain.Then turned ex cam and also intake electronic came to go in slot no luck.So I moved two this on each cam and started but absent badly, if ns repeat the what must be place of EX and also INT lobes?Is it possible that chain slipped at crank pair of teeth? If so is there any kind of other way to collection timing? i am lost and see no way out.
might need to begin from step one make certain number one cylinder is at TDC compression stroke. Take out plug have helper turn engine by hand finger in plug hole when feel compression set on mark. TDC can align top top crank to note for TDC of number one and BTC number one may be timing on the contrary cylinder.
i took the time chain turn off my wife's car because I had actually to change a head gasket. Now I to be trying to acquire the timing chain earlier together. I have actually it on the camer shafts and I am have it lined up on the starting marks in all three places. My question is, is that simply a starting point or will the marks heat up again after x amount of engine revolutions?
hello brittonadams, You space correct. The marks will realign themselves after a certain number of revolutions.
I carry out not understand if my 2002 2.5S Altima has a time belt or chain? and when it need to be inspected or replaced?Thank you, Jason
