I guess you have an HDI engine (possibly RHZ) as this fault is very common on that model. Quite possibly it will just disappear. It is not likely to be the turbo. Swap the electrovalve (pneumatic solenoid) which controls the turbo with one of the others (there are three beside each other on the inside of the wing, and see what happens. If the fault moves elsewhere that confirms electrovalve fault - so replace valve it.
If not check the vacuum hoses and test things such as the EGR for vacuum leaks. Another possibility is a faulty (or even just dirty) MAF. This is very easy to remove- it is on air intake - so remove and clean with wWD40 or similar.

My 02 Grand Vitara 2.0 RHZ HDI, was suffering from the same problems, giving me codes for selenoids valves, replaced the three of them did not solve the problem, finally a friend of mind told lets take down the Catalityc Converter, which we did and it was obstructed, took it apart, made a hole on the side eliminated everything inside, and solder it back, since then no more problems, the truck has more power, and no codes, after 20,000 kms this catalytic converter get obstructed, probably a factory defect,

What is code , po299' on mitsubish shogun 2008


the following answer is courtsey of OBD-CODES.com OBD Codes Your OBD-II Trouble Codes Repair Site Home Trouble Codes FAQs Forums Store P0299 Turbo / Supercharger Underboost OBD-II Trouble Code Technical Description Turbocharger/Supercharger "A" Underboost Condition What does that mean? The P0299 DTC code refers to a condition where the PCM/ECM (powertrain/engine control module) has detected that the bank "A" or single turbocharger or supercharger is not providing a normal amount of boost. That could be due to a variety of reasons, which we detail below. On a normally operating turbocharged or supercharged engine the air going into the engine is pressurized and that's part of what makes so much power for an engine of it's size. If this code is set, you will likely notice reduced power output. In the case of Ford vehicles, this may apply: "The PCM checks for a minimum throttle intake pressure (TIP) PID reading during engine operation, which indicates an underboost condition. This DTC sets when the PCM detects that the actual throttle intake pressure is less than the desired throttle intake pressure by 4 psi or more for 5 seconds." Symptoms Symptoms of a P0299 DTC may include: MIL (Malfunction indicator lamp) illumination Reduced power output from engine, possibly in a limp mode Unusual sounds from the engine/turbo There would likely be no other symptoms. Potential Causes Potential causes of a P0299 turbo underboost code include: Intake (induction) air restriction or leak Failed or damaged turbocharger (sticking, binding, etc.) Faulty boost/charge pressure sensor Faulty wastegate bypass regulator valve (VW) Low fuel pressure condition (Isuzu) Sticking turbo nozzle control solenoid (Isuzu) Faulty injector control pressure (ICP) sensor (Ford) Low oil pressure (Ford) EGR system fault (Ford) Variable geometry turbocharger (VGT) actuator (Ford) VGT vanes sticking (Ford) Possible Solutions First off, you'll want to repair any other DTC codes if present prior to diagnosing this code. Start with a visual inspection. Inspect the intake air system for cracks, loose or disconnected hoses, restrictions, blockages, etc. Repair or replace as required. If the air induction system tests OK, then you'll want to focus your diagnosis efforts on the charge pressure control, diverter valve (blowoff valve), sensors, regulators, etc. Really at this point you'll want to refer to a vehicle specific detailed repair manual for specific troubleshooting steps. There are some known issues on certain makes and engines so also check out our car repair forums here and search using your keywords. For example, if you search around, you'll find that a common fix for a P0299 in VWs is to replace or repair the diverter valve or wastegate solenoid. On the GM Duramax diesel, this code may mean the turbo housing resonator has failed. If you have a Ford, you'll want to next check the wastegate regulating valve solenoid for correct operation

1 Answer

Location of wastegate solenoid


If you do not know the location of the wastegate solenoid, how could you have properly tested it? Then, if you have not properly tested it, how could you possibly know that it actually needs to be replaced? - (just asking to provoke thought)

Hint: If you are getting a fault code that says "turbocharger wastegate solenoid control circuit" (like maybe a P0243), it would be wise to check the circuit before just throwing parts at the car...the solenoid might not be the problem.

With all that said, the answer to your question is that it is on the other end of the vacuum hose that goes to the waste gate valve - top rear of the engine above the left valve cover.

2. conect your voyager to the pc. there might be error on sensors that need to be removed. then it goes a had. i had this problem with mine. took me 10 min. to fix it

Check engine codes for a 1997 stratus the codes coming up are 12 31 and 55


12 Recently disconnected the battery (always stored)
55 End test.

CODE 31... depending on the model, code 31 can refer to two different systems. Please choose from one of the above links for specific information on each system.

Wastegate Solenoid Circuit Error
The ECM regulates turbocharger boost by opening and closing the "wastegate" as necessary. (The wastegate is a vacuum operated bypass valve that limits the ability of the turbo to provide boost.) The Wastegate Solenoid regulates the vacuum supply to the wastegate for proper operation.

Fault Code Description
  • 31 - Wastegate Solenoid circuit error
Symptoms
  • Lack of power or engine "ping" due to overboost by the turbocharger
Common Problems
  • The wastegate solenoid would be the most common cause for code 31 to set
  • Code 31 does not indicate a problem with the turbocharger or wastegate


Gear Position Switch (PRNDL) Error The Gear Position switch tells the ECM which position the shifter is in. The ECM will use this information to inhibit starter operation, change the transmission shift pattern as necessary, and provide the information for the electronic shift indicator display on the dash.

Fault Code Description
  • 31 - Gear Position switch (PRNDL) error
Symptoms
  • Engine may not crank over in Park or Neutral
  • Electronic shift indicator may flash
Common Problems
A maladjusted or failed Gear Position switch would be the most common cause for a code 31


Hope helps with this (remember rated this post).

Boost(?) problem audi tt


It is probably either the N75 valve(Diverter Valve) or the wastegate actuator. Usually a significant boost leak will set a DTC, still check all hoses and clamps.

A bad wastegate actuator or flap would cause no boost but not necessarily the air-sound.

____________________________________________
Testing N75

Air Bypass Valve: Testing and Inspection
With Generic Scan Tool
Wastegate Bypass Regulator Valve, Checking
Recommended special tools and equipment e.g.:
- VAG1526 multimeter or VAG1715 multimeter
- VAG1594 connector test kit
Test sequence
- Switch ignition off.
- Disconnect connector at solenoid valve for boost pressure regulation.
517f5c6.jpg - Measure resistance between terminals of valve.
Specified value: 25...35 Ohm
If specified value is not obtained:
- Replace Wastegate Bypass Regulator Valve -N75-.

________________________________________________

Testing N249

Exhaust Bypass Valve: Testing and Inspection
With Generic Scan Tool
Recirculating Valve For Turbocharger, Checking
NOTE:
Valve opens between connection to intake manifold and connection to deceleration shut-off valve with no voltage. Connection to vacuum
reservoir is closed.
Test sequence
- Switch ignition off.
- Disconnect connector from Recirculating valve for turbocharger -N249-.

9dfbfb9.jpg - Measure resistance between terminals of valve.
Specified value: 27...30 Ohm
If specified value is not obtained:
- Replace Recirculating valve for turbocharger -N249-.
If specified values are obtained:
- Connect test box to control module wiring harness, connect test box for wiring test.

1a741bd.jpg - Check wire between test box socket 105+2-pin connector terminal 2 for open circuit according to wiring diagram.
Wire resistance: max: 1.5 Ohm
- Also check the wire for short circuit to B+ and Ground (GND).
If no malfunctions are found in wire:
- Check wire between 2-pin connector terminal 1 and the Fuel Pump (FP) Relay -J17- for open circuit according to wiring diagram.
Wire resistance: max: 1.5 Ohm
If no malfunctions are found in wires:
- Replace Engine Control Module (ECM).

____________________________________________


To test the wastegate, locate the wastegate linkage rod and verify that there is no play and that it is closed. You can apply compressed air to the actuator to see if it opens and closes. (not more than 30 psi)
