In the old days the turbo would boost as soon as the engine speed was sufficiently high and any over pressure would be dumped by a relief valve or controlled by a wastegate.
In these modern times of electronics the turbo wastegate is normally open instead of normally closed so there is no automatic boost. The engine management system decides when there will be boost and how much boost there will be.
Turbo chargers are amazingly reliable unless they are abused or there has been foreign matter ingress. When looking for the cause of no boost it is wise to disconnect the intake trunking and turn the compressor vanes by hand to ensure all is well.
Disconnect the vacuum line to the wastegate servo and apply suction to the servo to ensure the servo, the linkage and wastegate is moving and in good order.
The next stage is to examine the vacuum line and connections back to source and then ensure the vacuum supply is adequate.
If all is found to be well with those physical checks the cause of no boost is either the failure of one of the vacuum switches (or the electrical wiring or connections to them) or a fault condition exists that has caused the engine management to decide not to provide turbo boost.
p0340 is the cam sensor, 0443 is the purge solenoid, 1249 is the wastegate on the turbo. The smell could be from 0443, it might be the solenoid on the evaporative system is bad or stuck, the cam error could be the sensor, wiring or the cam itself and the wastegate is the part of the turbo that dumps the excess compressed air that the engine does not need.
Check for spark at the wires leading into the cylinders that are misfiring. If you don't have spark, you may have a bad coil if you have one coil that runs all the cylinders. If you do have spark, you may have leaking injectors that are dumping fuel which is causing a rich condition. Check your spark plugs and see if they are wet. That may help in determining a leaking injector. Hope this helps. Good luck.
sounds to me that the accelerator pedal is bad if its an electronic pedal. youll know if its electronic or not by looking at the pedal if you see a set of wires or a wire harness plug into it then its electronic. if it is check the wires to make sure that they havent worked themselves loose if they are ok and the truck runs fine other wise then im leaning toward the pedal being bad another possibility is the injection pump it could be loosing suction because of a bad diaphram or bushing but id try the pedal first its the cheaper route.
The wastegate is a valve that regulates the ammount of boost that you turbocharger produces. The wastegate opens to release boost pressure.
This valve is electronicly controlled based on inputs to the onboard computer.
in your car the air ventilation system is freeze up causing a build up of pressure which caused the oil to burst out.there is the mosture sludge build up under the oil fill cap . its advisable to clean everything up and then check out by starting the car.also spray crab cleaner in the throttle body and check out.as per me the problem is causing because of :--I guess the breather vent tube was full of oil - frozen in there somehow. Must have to do with that sludge buildup on my oil fill cap. This is the one coming off the front on the left side of the oil filter. It goes down under the engine. This blockage caused a pressure buildup in the crankcase which caused oil to blow by the pistons and into the combustion chamber and out into the air intake hose and throttle body.get the spark plugs removed and cleaned up all the oil. The reason it sputter is because of all the oil in the combustion chamber. No air could get in. get the oil change and insulate the breather pipe in case of future freeze ups. This
will help. Thanks please keep updated.please do rate
the solution positively .thank you for using fixya
