NOTE:
If a VR sensor doesn’t pick up RPM signal, try to swap
the sensor wires (red and white wires)
A very simple test using a tester can identify if a Crankshaft Trigger
Sensor is an inductive or a Hall Effect sensor. Turn the tester on the
resistance measurement mode at a 2000Ω scale and connect its
probes to the sensor’s pins. Test pin 1 with the other two. If a resistance
of 600-1200Ω is found, the sensor tested is of inductive type.
If no resistance is found among any of the pins, or if the resistance
found is much higher than 1200Ω, it is either a Hall Effect sensor,
or an inductive sensor with a broken coil. Notice that, when finding

12.7 O2 sensor
Wideband O2 sensor
The use of wideband lambda sensors on FT500’s input requires an
external conditioner (WB-O2 Slim or WB-O2 Datalogger). It is important
to verify the measurement range of conditioner analog output, as this
will be informed during the configuration of FT500’s O2 input (0,65-
1,30, 0,65-4,00 or 0,65 to 9,99)
Narrowband O2 sensors
Although less precise than the wideband lambda sensor, narrowband
O2 sensors can be connected to the ECU input for the display of values
(in Volts) at the Dashboard and at the Diagnostic Panel. Narrowband
O2 sensors usually follow a standard set of colors, facilitating the
wiring. The table below shows the wiring instructions based on the
color scheme generally used for O2 sensor wires:
the resistance between pins 2 and 3, for example, pin 1 must be
connected to the battery’s negative terminal and the other 2 to FT
shielded cable. If the module does not capture the signal, invert the
white and red wires connections.
12.6 Camshaft position sensor
This sensor tells the ECU when the cylinder #1 is reaching its TDC on
the compression stroke. With this information it is possible to control
ignition and fuel injection in sequential mode.
Installation and alignment of this sensor are pretty simple. The only
requirement is that this sensor is triggered before the crank trigger
sensor goes through the gap on the crank trigger wheel.
