Feem ntau MAP sensor tsim tawm qhov hluav taws xob tso tawm ntawm 0 thiab 5 volts, nyob ntawm qhov ntsuas tau ntsuas. Yog li, cov MAP sensor yuav tsum muaj qhov ntsuas ntau ntawm 105 kPa ua rau kb15 kPa ua.

Raws li, dab tsi yog qhov ib txwm daim ntawv qhia sensor nyeem?

Cov zis hluav taws xob feem ntau nce thaum lub qhov rooj qhib thiab lub tshuab nqus tsev poob. A MAP sensor uas nyeem 1 los yog 2 volts ntawm idle may nyeem 4.5 volts mus rau 5 volts ntawm dav qhib throttle. Cov zis feem ntau hloov pauv txog 0.7 txog 1.0 volts rau txhua 5 ntiv Hg ntawm kev hloov pauv hauv lub tshuab nqus tsev.

Tom qab ntawd, lo lus nug yog, daim ntawv qhia yuav tsum nyob li cas? Li qub idle yuav tsum ua kom ruaj khov nrog tsis pub ntau tshaj 50 RPM kev hloov pauv. Nov yog thawj qhov qhia. Cov MAP kev nyeem ntawv voltage yuav tsum Qhov nruab nrab ntawm 0.9-1.5 volts. Lub tsheb no siab nyob rau lub sijhawm, qhia qhov siab hauv plab thaum noj.

Ib yam li ntawd, koj yuav nug, MAP kPa yog dab tsi?

MAP sensors ntsuas qhov siab. Txhawb cov ntsuas lossis ntsuas ntsuas ntsuas qhov siab tshaj qhov teeb tsa siab. Qhov teeb tsa qhov siab tshaj plaws feem ntau yog 100 kPa ua . Nws yog ib-rau-ib txoj kev sib raug zoo nrog qhov offset ntawm -100 kPa ua rau boost siab.

Kuv yuav paub tau li cas yog tias kuv daim ntawv qhia lub cim tsis zoo?

Cov cim qhia ntawm Broken MAP Sensor

  1. Poob Roj Economy. Yog tias ECM nyeem ntawv qis lossis tsis muaj lub tshuab nqus tsev, nws xav tias lub cav muaj qhov hnyav, yog li nws pov tseg hauv cov roj ntau dua thiab ua rau lub sijhawm tawg.
  2. Tsis muaj hwj chim.
  3. Kev tshuaj ntsuam xyuas tsis ua tiav.
  4. Rough Idle.
  5. Pib nyuaj.
  6. Hesitation los yog Stalling.
  7. Txheeb Xyuas Lub Teeb Pom Kev.
