— by kobd2 kobd2
A mileage of about a hundred and fifty,000 km, mvp key programmer manual outfitted LE5 type engine 2009 Shanghai GM Buick LaCrosse two.4 sedan. Consumer report: vehicle motor fault lights.

Inspection and analysis : detection motor management unit routine maintenance staff observed fault code P0171- motor torque manage exception. Observed launch x431 iv in the event the motor is idling the air flow meter facts , for your 1.8 g / s, and thru the air density is calculated from the information was two.86 g / s, exceptions. Then notice the amount of long-term fuel trim , observed right now has arrived at 17 %, indicating the air stream meter measurement error does exist.

Engine output torque is calculated depending on air movement charge , in case the air stream supplied the presence of knowledge error , then the result is certain to affect the torque . Detecting ZED BULL overall body command unit , it was located which the fault code C0241- driving steadiness command system torque reaction abnormalities. Therefore, to locate the reason for the malfunction , the air flow needs to be extensively checked.</p>

<p>Remove the air circulation throughout the main , it was found out in its sensing component amassed lots of dust , it really is very clear they will influence the operation of the sensor . This is due to the air stream is measured from the thermal element towards the air stream , and also the ingredient area of CRP129 the dust may perhaps impact the gas flow warmth exchange process.>

Troubleshooting: Thoroughly clear the surface area on the thermal element , once again observing air website traffic data , usually. Check confirmed troubleshooting.
