A mileage of about a hundred and sixty,000 km, equipped LZC engine 2007 3.0 Shanghai GM Buick industrial cars . People report: motor vehicle engine fault lights .
Inspection and examination : servicing personnel to detect the engine management device , identified fault code P0068 ---- throttle
bmw icom a2
entire body airflow overall performance P0101 ---- air movement sensor general performance and P0106 ??---- ingestion manifold complete strain sensor overall performance.
Check fault freeze body info , speed is 134 km / h, the throttle opening is 0 percent. Once the record crystal clear fault codes ,
examination failures arise . Had to evaluate the connection involving numerous fault codes . The actual throttle posture is as opposed along with the engine load is set in accordance to throttle position , the motor command unit to determine the air stream sensor in accordance into the motor load plus the ingestion manifold absolute strain sensor signal, the engine regulate unit via additional comparison , it is identified whether or not the sensor after the failure, will established the suitable fault code. If the motor handle device detects the present ingestion manifold absolute force along with the real air movement rate detected with the throttle place sensor along with a wanted pressure and air move complete inconsistent established DTC P0068.</p>
<p>Throttle position sensor in case the engine manage device detects the existing opening the throttle posture sensor plus the engine handle unit calculates the value in the predicted worth of inconsistency , will established the fault code P0121. DTC P0068 environment situation is really detected intake manifold complete air stress as well as the tachopro
desired strain change higher than a predetermined absolute worth , and the precise air movement charge plus the detected air stream price big difference is greater than the ideal predetermined benefit . Quite simply , the air circulation and calculate the actual detected the expected air stream deviation is simply too large.
Check motor details, only 17% of throttle opening , way too large , other information identified no abnormalities. Get rid of the consumption hose and located a whole lot of dust , after which you can remove its air filter housing , air cleaner uncovered no place, once the dust into your wire attached towards the cooling air circulation meter , air movement meter can't direct properly compute the actual ingestion air . Division of dust to the throttle , bmw icom abc
increase the throttle opening with the throttle opening degree gets more substantial foundation . And finally to the inside of the engine , elevated don of your piston as well as cylinder wall .
Troubleshooting: Cleansing the air movement meter, air filter and correct usage of certified installation, troubleshooting.
