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 solve code P0335 Hyundai Elantra 2013-2015


Hyundai 2013 model 

When the crankshaft position sensor of Hyundai vehicle is failing the ECU always displays code P0335 on its DTC.  Sometimes, this code can be displayed even if the sensor is not faulty, due to the reasons below:

·        When the battery is low and enough voltage is not reaching the sensor

·         When the timing plate is bent or cracked

·         When the timing of the engine is not correct

Until the above conditions are met, replacing the sensor might not solve the problem. It’s very important to cross check all the works you did on the engine, or to refer to repair history of the vehicle before going ahead to replace the sensor to avoid wasting money replacing parts that are not faulty.

Code P0335 will set when cra

nkshaft position sensor is rendered inactive, or when the sensor is faulty. When the sensor is rendered inactive,  check the following to pinpoint the problem:

1.       Double check the engine valve timing, especially  when your works on the engine involves altering the timing

2.       Check to see that you did not exchange the socket of crankshaft sensor with the knock sensor. The two sockets have the same designs but different power output. The power to the knock sensor is lower than that of crankshaft sensor, so exchanging the socket will lower the voltage on the CKP sensor . This will usually happens when you’re reassembling the engine.

3.       Check to see that the timing plate of the crankshaft is not pressed or bent in anyway. This usually happens when the crankshaft fell on the plate, take a careful inspection on the plate to see that it’s not cracked or bent in anyway. If this happens, code P0335 will be set on the vehicle and the engine will not rev up, even if it managed to start.

When the sensor is faulty, the following symptoms will surface:

1.       Check engine light will be displayed on the dashboard

2.       Sluggish or hard acceleration

3.       Intermittent power failure on acceleration

4.       Low idle rpm

If you’re observing this even while you did no repair work on the vehicle recently, and the scanning brought out the code P0335, kindly replace the sensor. This will permanently solve the problem and your engine will come back to life again.
