That is the ivtc on right cylinder head. Lh is shown in pic so yours will be on the back as well. Check resistance with connector disconnected. If not in the 730-890 ohm at 77 degrees then replace it if not that then it's either a cam sensor or another wiring issue.

Ok I think I see it. Its on the back of the motor? And it has some metal cover/plate over it right? I see it n the drivers side like u said I think but when I look up code p1135 for an 98 q45 it says P1135 Intake Valve Timing Control (Right Bank. So id need to do it on the pass side? If so is it on the pass side but same spot as the drivers side? I nvr did 1 on these cars is it a hard or big job anything I should kno b4 I try to do it? Any tricks u can tell me and is there a way to make sure or test it to make sure thats the prob

I looked up wrong code. Here is correct pic. Use voltohm meter an dtest yellow/green wire for voltage. If no voltage check fuse number 2 for blown. If still no pwer then check wire for being bad. Then use a jumper wire and test to see if solenoid works if it doesn't replace it. If solenoid operates check oil pressure an dair intake for blocakages. It's on passenger side

I think its on the back right above the tranny they have 2 one one the pass side one on the drivers side I taled to the dealer and told them code p1135 and they told me its on pass side back of the motor. The 1st pic u gave me thats it but thats the drivers one I need the pass side but u did help me when u showed me the drivers one thank you for the help and pointing me the right way with that one. But now im being told dirty oil/filter or needing an oil change can do this. Idk some ppl online I seen saying thy went thru this and put 10w 40 in and rest the light never had aa prob again I think imma start wit an oil change and go from there. Can dirty oil low oil dirty filter make the car pop that code? The car sat almost 14 months I just bought it so idk when the last oil change was or what they used cheap or good oil and filer. When I get time to change it imma do it and ill let you kno how I make out

I fyou look at the pic you will see your oil fill cap and the solenoid is right next to it. Change the oil and do what I said on last reply make sure to change oil filter and use either a napa, purolator, wix or bosch filter.

Try loosening and tightening engine grounds one on top left front of engine and battery lead that can cause it as well then have apro look at it so you save yourself some money and aggravation any garage should be able to fix this.
