נורת צ'ק אנג'ין נדלקה ובבדיקה ראיתי תקלה P0106 חיישן MAP.
בבדיקה ויזואלית החיישן נראה מחובר וכל החוטים אליו תקינים המנוע עובד עגול והרכב נוסע טוב.
לפני חודשיים בערך הייתה לי אותה תקלה, איפסתי את התקלה והכל היה בסדר עד אתמול.
אני לא יכול לפרק עכשיו ולבדוק והאישה צריכה לנסוע הערב נסיעה קצרה עם האוטו וההגיון שלי אומר שאין בעיה לנסוע עם האוטו.
האומנם?

Causes
A P0106 could be caused by:
Bad MAP sensor (http://www.amazon.com/gp/search?ie=UTF8&camp=1789&creative=9325&index=automotive&keywords=map%2Bsensor&linkCode=ur2)
Water/dirt intrusion affecting MAP sensor connector
Intermittent open in the reference, ground, or signal wire for the MAP sensor (http://www.amazon.com/gp/search?ie=UTF8&camp=1789&creative=9325&index=automotive&keywords=map%2Bsensor&linkCode=ur2)
Intermittent short in the reference, ground, or signal wire for the MAP sensor
Ground problem due to corrosion causing intermittent signal problem
A break in the flexible air intake duct between the MAF and the intake manifold (not broken, but at leak on the spot where the maf would be.)
Bad PCM (do not assume the PCM is bad until you've exhausted all other possibilities)
Possible Solutions
Using a scan tool, watch the MAP sensor value with the key on, engine off. Compare the BARO reading with the MAP reading (http://www.amazon.com/dp/B00SFBAEZM). They should be roughly equal. The voltage for the MAP sensor (http://www.amazon.com/gp/search?ie=UTF8&camp=1789&creative=9325&index=automotive&keywords=map%2Bsensor&linkCode=ur2) should read approx. 4.5 volts. Now start the engine and look for a significant drop in the MAP sensor voltage indicating the MAP sensor is working.
If the MAP reading (http://www.amazon.com/dp/B00SFBAEZM) doesn't change perform the following:
With the Key on, engine off, disconnect the vacuum hose (http://www.amazon.com/gp/search?ie=UTF8&camp=1789&creative=9325&index=automotive&keywords=vacuum%2Bhose&linkCode=ur2) from the MAP sensor. Using a vacuum pump, pull 20 in. of vacuum on the MAP sensor. Does the voltage drop? It should. If it doesn't inspect the MAP sensor vacuum port and vacuum hose to manifold for a restriction of some kind. Repair or replace as necessary.
If there are no restrictions, and the value doesn't change with vacuum, then perform the following: with the Key on and engine off and the MAP sensor unplugged, check for 5 Volts at the reference wire to the MAP sensor connector with a Digital Voltmeter. If there is none, check for reference voltage at the PCM connector. If the reference voltage is present at the PCM connector but not the MAP connector, check for open or short in the reference wire between MAP and PCM and retest.
If reference voltage is present, then check for existing ground at the MAP sensor connector. If it isn't present then repair open/short in the ground circuit.
If ground is present, then replace MAP sensor.
Other MAP sensor trouble codes include P0105, P0107, P0108 and P0109.
ברשת מדברים גם על דליפות אוויר מצינורות ואקום , איטום מכסה שסתומים - במיוחד אם יש שמן על הMAP סנסור .
ככל הניראה הרכב יסע עם זה בצורה סבירה ... אבל אני לא רוצה שום אישה זועמת על הראש שלי - מספיק לי אחת :)
