HU31035 Sensor Simulator
Reviewed by Brin Kline, owner and technician at
Assured Auto Works in Melbourne, Florida.
Q: How did the tool function
as far as saving you time?
A:This ANSED HU31035 Sensor Simulator
eliminates quite a few steps in the diagnostic
process. Without the simulator, the process
of verifying the circuit and, in many cases,
the ECU's funct ional ity, is more
Q: How was its packaging? Did it
come with any accessories?
A: This tool comes in a plastic, reinforced
clamshell case with a zipper. This set
includes the sensor simulator with attached
battery cables. The cables are nice and
The ANSED Diagnostic Solutions
HU31035 Automotive Sensor
Simulator is designed to simulate
and actuate the output signal from
automotive sensors such as frequency,
voltage, and test sequences. It's
especially useful for wiring tests. It
can simulate the signal and compare
it to the scan tool reading. The Sensor
Simulator allows users to eliminate the
need to replace sensors that work.
Users can simulate most sensors,
injectors or actuators, including ABS,
lambda, EGR, CKP, knock, and MAP
sensors. Simulator functions include
simulated resistance, voltage, sine
wave, square wave, and simulated
temperature coefficient sensors,
throttle and pedal sensor sequences,
as well as testing mode and simulated
mode of oxygen sensors.

professional. Where the cable is molded to
the alligator clips looks strong and reliable.
There is one red test lead and one black test
lead with banana connections on both ends.
This allows you to connect any probe or
accessory with the same banana-style plug.
There are two DVOM-style test probes and
two leads with alligator clips. Also included
are specification forms with links to videos
describing how to use the tool.
Q: How easy was it to use?
A: The tool is very easy to use. There are
only six buttons so navigating the user
interface is very simple.
Q: Was there a manual included? If
so, did you use the manual, and was
the manual easy to understand?
A: The user manual was included. It could
use more text. It has Ikea-type picture
walkthroughs that don't include much
text. Sometimes the text is needed to
understand what the pictures are trying
to demonstrate.
This product was given to the reviewer free of charge from the manufacturer.
Q: What features did you like?
A: I liked being able to vary the resistance
while monitoring scan data to verify that
the circuit and ECU were functioning as
designed. I also liked being able to do the
same with fixed voltage or producing digital
or analog waveforms.
Q: What types of jobs/repairs
did you use this tool for?
A:We used this to simulate a wheel speed
sensor when diagnosing the cause of an illuminated
ABS warning light. We connected
the simulator to the harness (with the sensor
still connected), then adjusted the frequency
output and monitored the wheel speed
data on a scan tool. This allowed us to verify
the circuit and ECU's functionality.
Q: Is there any way you could think
of improving or adding to this tool?
A: It would be nice if the battery cables had
an inline connection that allowed the user
to use alligator clips to connect directly to
the battery and a second option for connecting
to a power outlet in the vehicle.
I would also like to have longer battery
cables so we could connect to the battery
and still be able to test at most places on
the vehicle. As well as this, I would like the
cast to be a little larger.
Q: On a scale of 1 to 10, how would
you rate this tool overall? Why?
A: I love this tool! Sliced bread doesn't
have anything on sensor simulators. I
rate this tool a 9 only because of the suggested
improvements I described above.
Otherwise, I'm very happy with the tool
and would recommend it to any of my
friends or colleagues.
