Ther first code ECM-6805 TURBOCHARGER (TC) CONTROL VALVE DIAGNOSTIC TROUBLE CODE (DTC) INFORMATION If engine speed (RPM) is above 3500 rpm and the engine is operating at a high load, and if the boost pressure (from the boost pressure sensor) is higher than a designated value, which at maximum boost pressure is approximately 20kPa (2.9psi) above normal boost pressure, this is interpreted as a fault and diagnostic trouble code (DTC) ECM-6805 is stored. Condition reduced boost pressure Possible source * hoses between turbocharger (TC) and turbocharger (TC) control valve respectively turbocharger (TC) control valve and pressure servo are loose or are blocked/damaged * faulty turbocharger (TC) control valve * faulty boost pressure control (BPC) valve pressure servo * sticking boost pressure control (BPC) valve Condition * none ECM-6805 TURBOCHARGER (TC) CONTROL VALVE PRESSURE TOO HIGH - PERMANENT/INTERMITTENT FAULT Checking the hoses and turbocharger (TC) control valve Check that the hoses between the intake manifold, pressure regulator and turbocharger (TC) control valve are not trapped, blocked or damaged. Check the turbocharger (TC) control valve by activating it. Check the alignment of the boost pressure control (BPC) valve pressure servo and the boost pressure control (BPC) valve and that they are functioning correctly and not sticking according to See: Component Tests and General Diagnostics\Boost Pressure Regulator, Checking/Adjusting Verification Hint: After carrying out the repair, check that the fault has been remedied. * Ignition off. * Reinstall connectors, components etc. * Disconnect the VCT 2000 from the data link connector (DLC). * Test drive the car and check that high boost pressure is obtained. * Connect the VCT 2000 to the data link connector (DLC). NOTE: Do not switch off the ignition before the VCT 2000 has been connected and the boost pressure has been tested with the smart tool. Read the boost pressure fault status When the boost pressure has been tested the display should show that the diagnostic is complete. the second code Symptoms You will likely not notice any serious drivability problems, although there may be symptoms. Possible Solutions The simplest thing to do is to reset the code and see if it comes back. Then start with the cheapest, easiest repair procedures: Inspect for the following conditions: An incorrectly routed harness--Inspect the harness of the MAF sensor in order to verify that it is not routed too close to the following components: - The secondary ignition wires or coils - Any solenoids - Any relays - Any motors A low minimum air rate through the sensor bore may cause this DTC to set at idle or during deceleration. Inspect for any vacuum leaks downstream of the MAF sensor. A wide open throttle (WOT) acceleration from a stop should cause the MAF sensor g/s display on the scan tool to increase rapidly. This increase should be from 6-12 g/s at idle to 230 g/s or more at the time of the 1-2 shift. If the increase is not observed, inspect for a restriction in the induction system or the exhaust system. The barometric pressure (BARO) that is used in order to calculate the predicted MAF value is initially based on the MAP sensor at key ON. When the engine is running the MAP sensor value is continually updated near WOT. A skewed MAP sensor will cause the calculated MAF value to be inaccurate. The value shown for the MAP sensor display varies with the altitude. With the ignition ON and the engine OFF, 103 kPa is the approximate value near sea level. This value will decrease by approximately 3 kPa for every 305 meters (1,000 feet) of altitude. A high resistance on the ground circuit of the MAP sensor can cause this DTC to set. Any loss of vacuum to the MAP sensor can cause this DTC to set. the third code O2 sensor failure may not be displayed appropriatly

SOURCE: Sputtering problem

change the fuel filter with a new one
let it come to operating temperature before you gun down the pedal to the medal
get a fuel cleaner injector cleaner.
turbo works good at operating temperature.
how is oil presure ?

SOURCE: i have fault codes po105,p1105,p0100,p0234,what is

The missing codes may be Saab-specific but two were found:
- P0105= MAP/BARO Circuit Malfunction - P1105 not listed - P0100 " " - P0234= Engine Overboost Condition
If in the US or Canada, check with a chain auto parts store, they may have all of the codes.
Hope that helps-

SOURCE: i got a p0234 code

sounds like the injector pump is out of time or going bad ... check notches on pump and intake make sure they are lined up... injector pump will be in the valley which is top front of intake it will have 8 fuel lines coming off it to each injector it should be a 14 or 15 mm bolts on back of pump

What is the P0234 code on my 2005 pt criuser


P0234 over boost condition has occcurred. press the helpful button
The symptoms displayed for a P0234 code will depend on the cause of the overboost condition: The service engine soon or check engine light will illuminate. You will experience a loss of power. The engine may show signs of overheating. The transmission may show signs of overheating and harsh shifting. Additional codes associated with the condition set by P0234 may be present to help identify the cause. Codes are available for all electrical components utilized by the engine management computer for the control of boost levels. The engine may display signs of pre-ignition in the form of knocking. The engine may display ignition misfiring.

AUDI A3 OVERBOOST 20. TDI 04 SAFE MODE ISSUE


Code P0234 Check N75 boost control solenoid and all vacuum hoses to and from N75.

If performance returns after brief ignition key cycling, Off /On.....check for vacuum to turbo dump valve canister.

If performance is always low, check turbo vanes for sticking or 'snow screen' in snorkel to air filer is not restricted..

P0135. Turbo boost pressure too high.

O2 sensor heater malfunction: ...Check all fuses. If good, replace O2 sensor.

Over boost: Check N75 Boost control solenoid and all vacuum hoses to and from N75.

1st & 2nd gear, then complete loss of power. audi a4 tdi 2007


I presume you experienced a loss of full power but had enough to get home. The check engine lamp came on too?

It seems your engine is in limp mode due to a possible over boost pressure . The ECU runs the engine with reduced power after an over boost is detected. If you cycle the ignition key and power comes back, this is most likely problem.

A fauliy N75 solenoid, with three small bore vacuum hoses and an electrical plug/connector, is possible cause .

This over boost can be caused by sticking vanes inside the turbo .

Have it scanned and read the codes. Code P0234 will be set if over boost occurred.

Code p0234


P0234 Description
The boost pressure sensor responds to pressure changes in the intake manifold. This pressure is created by the turbocharger and changes with accelerator pedal position (APP) and engine speed. The engine control module (ECM) uses this information to assist in diagnosis of the barometric pressure (BARO) sensor and to provide engine overboost protection. The boost pressure sensor has a 5-volt reference circuit, a low reference circuit, and a signal circuit. The engine control module (ECM) supplies 5 volts to the boost pressure sensor on the 5-volt reference 2 circuit, and provides a ground on a low reference circuit. The boost pressure sensor provides a signal to the ECM on a signal circuit relative to the pressure changes. The ECM monitors the boost pressure sensor signal for voltage outside of the normal range. The ECM calculates a predicted value for the boost pressure sensor. The ECM then compares the predicted value to the actual signal.

Would a faulty DIM on a volvo affect turbo function...p0234?


Overboost could be caused by anything from a faulty TCV, split hose or dirty MAP sensor. A replacement DIM won't change the running of the engine.

Turbo overboost po234. how to correct?


p0234 is engine over boost condition. According to Volvo P0234 is a turbo control valve. Maybe a wiring issue?
Did you do a hard reset after clearing the code? hope this helps!
