Index by Sensors
There are 3 possible actions for each sensor.
[T] Test. Means that the HMP1 can check the functionalit of sensor
outside the car ( or disconnected)
[R] Read. Means that the HMP1 can read the sensor without
disconnect from car and read/monitor the sensor while is working.
[E] Emulate. Means that HMP1 will act like the sensor, so the
injection will think that the sensor is placed and working.
Is important take care that not all sensors can be tested outside from
car, not all can be emulated and not all can be readed.
Example 1: The Ox gen sensor ( lambda ) measure rest of ox gen in
the exhaust but the need 300°C(572°F) to work. So for testing ou
need a place with more than above temperature and without exo gen.
So ou can read and emulate the sensor but ou cannot test
it.
Example 2: The IAC valves have not feedback, so the injection never
know the real position of valve. So ou can see and watch the
movement, but ou cannot read or emulate.
Each sensor have require an individual anal sis, but the following
table resume what ou can do with each sensor.

Connecting Power Supply
The device need 12Vdc continuous to work. Become with 2 crocodiles
to allow connect to car batter . An wa can be connected to a
12V@4A stabilized power suppl like notebooks.
Do not use batter chargers without car batter .
Connecting probe cables
The device have 2 connectors in the rear part. The main have 6
contacts, used on most cases. And the extra with 14 contacts that ou
will use in fewer uses, normall when exercise the ECU.
Main:
Uses a Terminal Block of 6 wa with pitch of
5.08mm ( 0.2”). The main connections are as image
and must take care when assemble of new throttle
bod and pedals. Other uses are detailed in
appropriated section.
The image is looking the screw with the pluggable
area at left and the wires in the right side.
Extra:
You can use a IDC14 connector or pins of
0.1” (2.54mm) for the connections.
(Normall sell for Arduino)

Select test Type
After connect 12v, appear the main menu.
Using the ke s “+” and “-” ou will see
different test.
When ou see into the screen the right test,
press OK.
Testing an electronic throttle
There are 2 functions that allow test and move the throttle bod . Both
functions are completel different on their working mode but similar
in the wa to use.
“Throttle”, Ever time that ou press “+” or “-” the applied
power to the motor will be greater or lower, and the movement is the
result of this power. Is good to clean the bod , test the gears, and see a
smooth and eas movement. You can help the displacement with the
hand.
“Search”. Ever time that ou press “+” or “-” is applied to
motor the required power to force a specific point of throttle. This
allos a more accurate position of butterfl . The s stem read the
position on TPS sensors, so an fail in the sensors can cause an erratic
movement of butterfl . This test mode is good to check the TPS tracks
to search for cuts or jumps. Try to move with the hand will result on
HMP1 damage.
1 The engine must be OFF before an test. Doing with the engine
running can damage the engine.
2 Search the appropriated connector and check the connections.
Alwa s verif that the coil is connected to the terminals COIL+ and
COIL- and the rest of connections according the following diagram.
In the section “preassembled wires” ou will found useful information
for this verif process.
5/36

3 Connect the 12v, in the main menu search the word “Throttle” or
“Search” and press ”OK”.
4 In the screen ou will see 4 data similar to the image:
A=TPS differences
B=Motor current
C=TPS1 position (in %)
D=TPS2 position (in %)
The difference of TPS is the most important data that look the ECU to
enter in emergenc mode. Both sensors TPS1 & TPS2 must have a
defined relation, a coherenc , The HMP1 read both sensors and show
the difference between ideal read (mathematicall calculated) and the
real reading taken from TPS.
The maximum difference tolerated b ECU change from car to car, but
generall is up to 5% of difference.
5 Move from extreme to extreme the butterfl using “+” and “-”
ke s. The s stems will be register all data coming from sensors with
the finalit of found and problem if exist.
6 Automatic mode:
In “Throttle” mode: if press “+” and “-” simultaneousl the
butterfl will start to move from extreme to extreme automaticall .
Will continue moving until ou press an ke .
In “Search” mode: if press “+” and “-” simultaneousl ou
can set the min and max position to be moved. Is god to check deepl
one suspected zone of TPS.
7 Pressing the OK button, ou will see a complete report with the
6/36

collected data.
Note: The throttle must be connected BEFORE of start the test.
Note: If the TPS relation is not recognized the “Search” mode do not
will work.
Report on screen
After perform the test, the tester will have enough information to show
a result on screen.
Press “OK” ke , and the report will appear. Use + and – to change the
parameters showed, and OK when ou has seen ever thing.
TYPE: Used formula to check the consistenc of TPS of throttle or
pedal used. Are 4 possible data:"T1&2=100", "T1=T2x2", "Toyota".
"Unknown" mean that cannot be recognized the relationship,
probabl because a bad connection, critical failure of throttle or a new
and unknown bod for the HMP1.
TPS1: Report OF integrit of TPS1 with the following data.
A=Tps1
C=Continuit
B=Minimum registered
D=Maximum registered
The device make 2000 read b
seconds to the TPS, the continuit is
the most greater jump between 2
consecutive measures, the objective
is tr to discover an damage in the
track of sensor.
TPS2: Same as TPS1.
Maximum Difference: The TPS1 and TPS2 have a relationship
(different according the car). The difference is the error between ideal
relationship and the reall measured in both sensors. The HMP1
monitor permanentl this difference and record What was the
7/36

maximum difference and where was the position of TPS when the
occur.
B=Max Difference found
C=Position TPS1
D=Position TPS2
Isens: Is the current that require the sensor to work,
Tps Swap: The device cant detect if the TPS1 and the TPS2 are
inverted. This data generall is a permanent propert of bod , but a
mistake in the connection can be exposed here.
“no-swap” Means TPS1=TPS1 and TPS2=TPS2
“swap” Means TPS1=TPS2 and TPS2=TPS1
I_coil max: Max current demanded b motor. To discard short circuit
or gear damaged.
Pol coil: Motor Polarit .
M1+ M2- means that the throttle open when the voltage on
M1 is greater than M2
M1- M2+ means that the throttle open when the voltage on
M2 is greater that M1
Result: Result off anal sis. This data must not been taken as absolute
answer, onl as orientation.
GOOD, the max difference is lower than 4%.
DOUBT, the max difference is between that 5 and 6%.
BAD the mas difference is greater and can cause problems.
8/36

Test of Electronic Peda
Connect the pedal using the appropriated connector, or use a crocodile
to connect as is showed on the image.
After that must use + and - until see PEDAL and press OK.
Now ou will see 4 information's similar to the image:
A=Is testing a pedal
B=Difference between C and D
C=Position TPS1 (in %)
D=Position TPS2 (in %)
To test, alwa s with the engine stopped, press slowl the pedal until
reach the max, Avoid the hard movement.
The HMP1 will calculate the coherenc of sensors TPS & TPS2, and
will show in screen the difference between TPS1 & TPS2 real
relationship and ideal. Is the most important data that read the ECU
looks.
Pressing OK button ou will see a complete report. Similar as throttle
bod except data related to motor
9/36

Analog sensor read
This function measure the voltage provided b the sensors. At difference of a
regular multimeter the HMP1 make 2000 reads b second that allow found
errors mostl on TPS. For the rest of sensors ou will found useful the progress
bar in the bottom of screen.
To start the read in the main menu press + and - until see SENS AN and press
OK.
This function allow measure TPS,
MAP, MAF and another sensors with
analog output between 0 and 5v. The
connection can be made using a wire
puncturer to TPS1 input or making a
complete harness like graphic.
In the screen will appear the following information:
A=You are reading an analog sensor
B=Progress Bar
C=Voltage read from sensor
TPS: Normall have a voltage between 0.7 to 4.7v. Opening slowl the
throttle searching fails like explained on throttles.
MAP: With the engine stopped must read 4.7v, with the engine on Idle must
be 1.4v. Do a single hard throttle and then wait for the engine to come to idle.
The voltage must be raise to 4v when is throttling, and a lower than idle value
when engine RPM is decreasing.
MAF: With the engine stopped must read 0v, with the engine on idle must be
1.2V. In a hard throttle for a small moment will have 4v, after that a fall to
1.5v and finall start to grow the voltage like RPM is rising.
Pressing OK back to main menu.
