What is fault code SA 16 DTC PO 4D900


Looks like could be caused by one of several sensors.
I did find thisP04D9 EGR feedback saturation This OBD monitor indicates if the burned air fraction error is saturated against a high or low limit. The logic for the monitor evaluates the time spent at saturation and compares the ratio between the time spent in a saturation mode and the total time engine running. A fault is reported whenever the ratio exceeds the fault limit.
P04D9 EGR system: Feedback control(Saturated Low)
Enable conditions: Engine torque 300 - 2500NM,Exhaust Mass Flow 0.1 kg/s, Ambient Air Temperature-8 -55C, Barometric Pressure 75 - 105 kpa, Coolant Temperature>65 C
Disable Conditions No active DTCs P0069 P046c P0234, P0299, P0401, and P0402
Some possible causes
P0069 Intake manifold pressure sensor evaluation
P046c EGR differential pressure sensor: DP Sensor rationality
P0234 Comparison of actual boost pressure, Overboost, to modeled boost pressure
P0299 Boost Pressure: Underboost, Comparison of actual boost pressure to modeled boost pressure
P0401 EGR system (low flow)compare demanded egr flow to actual
P0402 EGR System (High Flow)compare demanded egr flow to actual

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

Check engine light codes reads 16683


16683/P0299/000665 - Boost Pressure Regulation: Control Range Not Reached Possible Symptoms
  • Reduced Power Output
  • Limp Mode
Possible Causes
  • Hoses/Pipes incorrect connected, disconnected or leaking
  • Charger Pressure Control defective
Possible Solutions
  • Check Hoses/Pipes to/between Components
  • Check / Clean / Replace Charge Pressure Control
Special Notes
  • When found in 2.0l TFSI:
    • Check Boost Pressure Control Valve (N249), for cracked rubber diaphragm. A new/optimized Valve is available under Part # 06F-145-710-G (or newer), see TPI 2016331 for details.
