Head gasket replaced, lost timing in sprockets, after countless tries, have TDC rightchain yellow clues aligned each camshaft okay, according to diagram. Check out no marks in cover other than drill note on sheathe exhaust cam, near 10 mm bolt.Intake electronic came mark in ~ 9 o'clock.Have compression 130 approximately. Rotate engine on, no lucky removed and also grounded spark plug no fire!Plugged scanner and also shows electronic came sensor failure and air fuel metering problem.
shows code P1111 and P0340. Auto was to run fine simply for burn exhaust valve (replaced).My concern still is, proper means to align cams? had actually TDC and also the two yellow clues in chain to mating marks in sprockets however after turns by hand, will certainly not enhance again.Is firing note number one in slot that intake video camer is come be exactly aligned with sensor.Please be as in-depth as girlfriend can. Ns am very frustrated and also my child wants vehicle out!
time chain marks 26 links between gold/yellow mark on chain and also 64 links between camshaft sprocket and gold/yellow link and also crankshaft sprocket orange/blue link on the time chain next without the tension-er. See diagrams.Were password present before head removal? and also injector pulse?
as I described earlier, there to be no password 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 point out on top and sprocket clues on every yellow mark.Any other suggestions? Is it possible, no fire because camshaft not in place with spark sensor?
P0340 fault in camshaft position sensor either open up or shorted or out of phase situated on behind head is that plugged in wiring intact?P1111 fault Intake valve timing control either defective or open up or shorted IVTC needs to be removed during repair have to not it is in disassembled. Is solenoid connected wiring intact?
Got automobile started after transforming engine by hand several times and matching yellow mark in chain and sprockets, this is what i did;number one cylinder TDC set with mark bottom cover and also two yellow clues on height of chain.Then rotate ex cam and intake cam to walk in slots no luck.So I relocated two teeth on each cam and started but absent badly, if ns repeat that what have to be place of EX and INT lobes?Is it possible that chain slipped at crank pair of teeth? If therefore is there any other method to collection timing? ns am lost and see no way out.
might need to start from action one make sure number one cylinder is in ~ TDC compression stroke. Take the end plug have actually helper turn engine through hand finger in plug hole when feel compression collection on mark. TDC can align on crank to note for TDC of number one and also BTC number one might be timing on the opposite cylinder.
ns took the timing chain off my wife's auto because I had actually to replace a head gasket. Now I am trying to get the timing chain earlier together. I have actually it on the cam shafts and also I am have actually it inside wall up top top the starting marks in all 3 places. My question is, is that simply a beginning point or will the marks line up again after x lot of engine revolutions?
hi brittonadams, You space correct. The marks will realign us after a certain number of revolutions.
I execute not understand if my 2002 2.5S Altima has a timing belt or chain? and also when it should be inspected or replaced?Thank you, Jason
2.5L has timing chain with no continual maintenance interval. Chains only need replaced if castle are producing a trouble i.E. Rattling, link damaged etc.
