18. Troubleshooting

If sensor terminal is fixed well

Check if PCB is faulty,

if yes,

replace it

If sensor resistor

/characteristic is proper

Reconnect

Replace sensor

Yes

[20~24] Temperature sensor failure

If sensor terminal is fixed well

If voltage between red terminal

and black terminal is 5V when

testing pressure sensor by

multimeter

If voltage between white terminal and black

terminal is 0.5V~3.5V when testing pressure

sensor by multimeter

Replace connecting board

Reconnect

Replace PCB

Replace pressure sensor

Yes

[28, 29] High/low pressure sensor failure
