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'

How to Reset a Check Engine Light Check engine lights go on when there is a problem in the engine or the emissions control system. You should always have the codes generated by your car's computer scanned and read so you can determine the cause. You can reset the light once you have fixed the problem. This article will tell you how to reset the check engine light in your vehicle. Method One of Two: Use a Code Scanner 1 Connect the scanner to the on-board diagnostic connector (OBD-II) under your steering column.  Turn your ignition switch to "On." Turn off all accessories. 2 Press the "Read" button on your scan tool to view the engine's error codes. Write down the code or codes in the order they were received for future reference and repairs if necessary. 3 Press the "Erase" button on your scanner to clear the error code. Clearing any codes present will turn off your check engine light. Some scanners

Engine unable to start but cranks

If the fuel pump is not delivering adequate fuel pressure and volume to the engine, the engine may not start or run properly. Low fuel pressure can cause hard starting, a rough idle, misfiring, hesitation and stalling. No fuel pressure will prevent the engine from starting, or will cause the engine to quit running if the fuel pump fails while driving. Fuel injected engines are very sensitive to fuel pressure as well as fuel volume. Low pressure will cause starting and driveability problems. A pump that can deliver adequate pressure but not enough volume may allow the engine to start and idle normally, but it will starve the engine for fuel and cause a loss of power when the engine is under load, accelerating hard or cruising at highway speeds. Engine Cranks But Will Not Start A dead fuel pump can prevent an engine from starting, but so can a problem with the ignition system or the engine itself (such as a broken timing belt). The first thing to check would be spark. This can
