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'

Eight things that cause black smoke from your car's engine

Engine of a car will exhaust a product of combustion, which, if all things being equal are steam and carbon dioxide. Steam (H2O) and Carbon IV Oxide (CO2) are the product of combustion with traces of oxides of nitrogen and hydro-carbons in car's engine Some of the unburnt fuel particles, will be exhausted as hydro-carbons, and excessive heat of the Engine will convert some of the available oxygen meant for combustion into various nitrogen oxides. Which, if present  in excess is harmful to our lives and the environment.  Because of this, there is a legislation in the industrial countries on the amount of each of these substances to exhaust from any Engine that's built to work on public roads. Car Engine manufacturers want to stay in business, and also want to obey the laws of the land. They started building Engines with devices that will help ensuring a near complete combustion to limit the excess hydro-carbons to the environment and also inhibitors that will l

How faulty ABS can stop automatic transmission from shifting

Your car's ABS system is a technology towards a greater safety and uptimum driving comfort. However, it's malfunction can result to so many problems in the car.

The same things happen to All other Toyota vehicles from 2003 model to latest that are equipped with the ABS system. What we're discussing now is about Toyota vehicles 2003-2012 that are equipped with the ABS system. This discussion also applies to Lexus vehicles of the same year as the Toyota mentioned Here are what you'll learn  Technology behind Wheel speed sensor How the wheel speed sensor can stop the work of the transmission overdrive. You'll also learn how you'
