How to solve code P0015 and P0017 (Toyota or Lexus) of vehicles having rough idling and hard acceleration

Image
When your Toyota or Lexus cars have just started idling rough or not accelerating easily the way it used to be, you plugged in a scanner and found out the codes P0015 P0017 (both current), as shown below. when this happens, the engine-valve timing is altered.  P0015   P0017 how can engine-valve timing be altered even when no body loosed the engine? Most of the new model vehicle are equipped with variable valve timing inlet (VVTi) camshafts, which help adjust the valve timing of the vehicle when operating on certain loads, to help boost the engine performance at that particular instance. then readjust the timing to the normal point on average working conditions.  But when an ECU commanded the VVTi cam gear to return to the normal point and it's not working, this'll prompt the computer to throw the code P0015 or P0017 or both accuring at the same time, with the check engine showing on the dashboard. When the cam gear failed to return to the normal point after adjustment, this'

Causes of vibration above 60 mph of GL450 Mercedes Benz

GL450 vibrating above 60MPH


Vibration above 60 miles per hour while driving your GL or ML is caused primarily, by either a propeller shaft or the flat washer of the lower arm bushings.

Lower arm bushing will cause the vibration if:

  •          It’s broken
  •          You Changed the position of the flat wide washer: the washer on the big bushing of the lower arm supposed to be at the right side of the bushing. If it’s changed from this position to the front end of the bushing, it’ll destroy the alignment of the lower arm and the bushing. This, if you're accelerating at a high speed above 60 mph, it’ll draw the iron in the bushing to the chasis of the vehicle. This you’ll feel as a vibration while speeding. This situation usually disappears when you lower your speed below 60mph. 

lower arm bushing washer will be at the right side of the bushing, not left  

Propeller shaft and driving shaft

A broken driveline of the propeller shaft can cause the vibration of GL450 above 60mph


  •          They’ll be a vibration if there’s no grease in either the propeller shaft or the driving shaft
  •          If the bearing of the propeller shaft is broken
  •          If the cup of the driving shaft is worn out

Other culprits are broken transmission mounts, bent rim(s), bad tyres  and  bad wheel alignment
