8. WB-O2 Meter Nano Codes
8.1 Informative Codes
When turning WB-O2 power on, the following information will be displayed:
Product name
Measurement unit (Lambda, AFR gasoline, AFR alcohol or AFR Methanol)
Analog output scale (as seen on chapter 6)
EN
Cylinder identification (when connected via CAN with Power FT ECU's): tells
which cylinder the conditioner is reading, when used for individual cylinder
adjustment.
Then the word HEATING indicates the O2 sensor heating for operation.
After heated, the word HI appears when AFR above 146.9 AFR Gas (64.1
AFR Alcohol) is read.
8.2 Error Codes
Cód
12
Descriptor
E01: internal processor error
E02: Sensor disconnected or damaged
E03: Short circuit with the positive on the
sensor's heater or damaged heating element
E04: Short circuit with the positive on
the sensor's heater or damaged heating
element. Power ground problem.
E05: short circuit with the ground on the
signal cables or Interference in the O2
sensor signal cables
E06: short circuit with the positive on the
signal cables.
E07: battery voltage under 10V (normal
when cranking engine)
E08: if it blinks during power on, it indicates
a communication error. If this code keeps
fixed on the screen, may indicate a damaged
O2 sensor or WB-O2 Nano unit
Procedure
It is necessary to send the equipment to
FuelTech for repair
Check connections of the O2 sensor
Check connections or replace the O2 sensor.
Check power ground connection
Check connections or replace the O2 sensor.
Check power ground connection
Check connections or replace the O2 sensor.
Check power ground connection
Check sparks, sparks plugs and cable
passageway
Check connections or replace the O2 sensor.
Check power ground connection
C h e c k u n i t p o s i t ive a n d n e g a t ive
connections.
Try another O2 sensor. If the problem
still unsolved, it is necessary to send the
equipment to FuelTech for repair
