 Posted by  Posted on September 30, 2020

FUNCTION

  • The barometric pressure sensor converts the barometric pressure into a voltage signal and inputs the signal to the engine-ECU.
  • In response to the signal, the engine-ECU corrects the fuel injection amount, etc.

    • TROUBLE JUDGMENT

  • Battery positive voltage is 8 – 16 V
  • 2 seconds later after the ignition switch has been in “ON” position or the engine has started up
  • The barometric pressure sensor output voltage is 4.80 V or less for 0.5 second.

    • PROBABLE CAUSE

  • Failed barometric pressure sensor

    • DIAGNOSIS PROCEDURE

    STEP 1. M.U.T.-III data list

  • Item 5: Barometric pressure sensor

    • Q. Is the check result normal?
