Грешката ако е 6806, то симптомите са описани по-долу. Явно сте проверили/сменили най-честите виновници за грешката. Ключа към решението е диагностиката и дали налягането е по-високо или по-ниско от нужното след 3500 об/мин.
------------------------------------------------------------------------------------------
ECM-6806 Turbocharger (TC) control system flow fault. Flow too high/low.
Diagnostic trouble code (DTC) information
Condition
If engine speed (RPM) is above 3500 rpm and the engine is operating at a high load, the control signal to the turbocharger (TC) control valve is at maximum and the boost pressure (from boost pressure sensor) is lower than a designated value (approximately 20 kPa (2.90 psi) under normal boost pressure - signal too low).
If the air mass (from mass air flow (MAF) sensor) is higher than a desired value (signal too high) it is interpreted as a fault and diagnostic trouble code (DTC) ECM-6806 is stored.
Substitute value
reduced boost pressure
Possible source
Signal too high:
- air leakage after turbocharger (TC)
Signal too low:
- 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
Fault symptom(s)
DL2, Warning lights and chimes/Malfunction Indicator Light ("Check engine" light) indication/no indication
Driving/Poor performance/lacks power
Driving/Hesitates/surges/Unsure when/at all times
