Urea firikwed

Ana amfani da gaban firam ɗin urea na urea don gano matsin lamba na UREa, kuma ɓangaren baya shine alhakin gano matsin lamba na urea da iska a cikin ɗakin haɗuwa. Lokacin da bangarancin ya gaza: yawan amfani da urea mahaukaci ne, kuma abin hawa ya haskaka hasken. Lokacin da lambar kuskure ita ce laifin yanzu, wasan injiniya yana da iyaka cikin sauri da Torque.

Binciken da kuma masu gyara sigogi:

Use a multimeter to measure the open circuit voltage of the urea pressure sensor, turn on the key switch and unplug the key plug, and measure 5V (power), 0V (signal) and 0V (ground). To measure closed-circuit voltage, first turn on the key, plug in the plug and break the wire at the back to measure the voltage, measure 5V (power), 0.8-1V (signal) and 0V (ground).

Lambobin Laily Codes:

Alamar layin layi:
