What is the ELECTROTHROTTLE ETC Electronic Throttle
Actuator Tester?
Here's an automotive diagnostic tools designed from the
beginning as a full electronic throttle control and
solenoid unit. Using the same circuitry as the
automobile ECM, this unit is tough, made to last and
extremely accurate. It can actuate the ETC electronic
throttle with a fine tuned precision needed to be able
to test the internal dual TPS sensors. It is also needed
and useful when cleaning the throttle body plates. Here
are possible uses for the ELECTROTHROTTLE:
- When cleaning the electronic throttle body plates.
- To be able to find sluggish and binding ETC
electronic throttle mechanisms and gears.
- To test the ETC throttle body "Return Spring", which
over time weakens and causes issues.
- A useful "ETC Rebuilder's" 400Hz setting actuated
the ETC a few times per second, thereby performing a
month's worth of activity in 10 minutes.
- Whenever you need a secure way to open the throttle
body and not to worry about your fingers.
- If you need to test all sorts of solenoids with the
400Hz setting, like the transmission pressure control
solenoid, shift solenois, EVAP purge and vent valves,
PWM hydraulic solenoids and any other 12 PWM operated
electric valve.
- PWM Duty-Cycle controlled motors, such as PWM
radiator fan motors, AC Blower Motors and other DC PWM
controlled motors.
- Used to test ETC internal Dual or Triple TPS
(throttle position sensors).
- The Fine-Tuning of the 20,000Hz (20KHz) PWM
Duty-Cycle control signal is above the resonant
audible frequency of the human ear. It is also
absolutely important when doing "Very slow ETC
throttle actuation" to determine if there is a blind
spot at the TPS or throttle position sensor.
- Work on the ETC system with confidence that you will
not create other ETC issues with the ECM settings.
- Work with the Key OFF and Engine OFF, so no danger
of messing up the ETC drivability memory and causing a
limp-in mode.
As you can see, the ELECTROTHROTTLE ETC Electronic
Throttle Actuator Tester is a one and only diagnostic
unit. You can also use it in conjunction with a graphing
meter (Vantage) or Scope to monitor the signal and
analyze the motor's general health.
In general terms, cleaning the throttle body is a must.
Moving and manually operating the ETC electronic
throttle body plates, while the ECM is commanding it to
open is "A BIG NO". You will create more problems, since
the ECM will detect an ETC error, set a code and the
vehicle goes into limp in mode. With the ELECTROTHROTTLE
you "Disconnect the ETC connector and place the ECM out
of the picture". It's that simple. A useful tool for
21st century ETC systems.
