What you need to know (please read before ordering)

This is a Repair Service of your existing module. You will need to remove and send your module to us for repair using the shipping labels provided to you.

Please Note: We are usually able to repair these ETMs the same day they’re received. However, due to issues with parts availability, these repairs are taking longer than usual. The expected turnaround time is currently between 2-5 business days, but we recommend planning for an additional day or two just in case.

The order will be processed during our regular business hours (Mon-Fri 8:30 – 5:00 EST). After processing your order, we will email shipping labels and shipping instructions. If you don’t see shipping labels within 1 hour of submitting your order (during business hours) please first check your junk/spam folders. If you still don’t see the labels, please contact us at 1-888-712-2525

Please Note: We recommend that you replace the Mass Air Flow (MAF) sensor whenever the ETM is replaced, even if the MAF appears to be working properly. We have several genuine MAF sensors available.

Features:

Plug & Play: The software and settings will not be modified, making this module plug and play. No software reload or calibration is required after installation.

Quick Turnaround: Your module will be tested, repaired, tested again, and sent back to you in the same day (unless otherwise noted).

Contact-less programmable dual-sensor TPS upgrade: Zero wear Hall-Effect dual Throttle Position Sensor, designed and manufactured by XeMODeX. This contact-less TPS design eliminates any friction related TPS failures. XeMODeX TPS sensors are fully programmable unlike the clones out there which are pre-set and locked. Each of the two sensors sends its own throttle angle position to the ETM the closer the angles are to each other the quicker the throttle response will be. This is why we program each sensor on the actual ETM ensuring that the maximum deviation between the two sensors is less than 1.5 degrees (Maximum allowed deviation in the original throttle is 14 degrees before the software triggers the TPS sensor fault codes).

Brand New Stainless Steel Bearings: Steel bearings upgraded to stainless steel to better withstand corrosion.

Remanufactured Internal ECU: All fragile aluminum wire bonds inside the ECU are replaced with reliable copper bonds to prevent future joint failures.

Rebuilt Magnet Assembly: The magnets inside the DC motor are completely overhauled and sealed to prevent moisture penetration and subsequent corrosion.

Brand New Oil Rings: Brand new oil rings on the main shaft and the end caps.

Brand New Inspection Cover: Brand new custom manufactured aluminum inspection cover.

Full Test Report: Every ETM is quality tested, and a test report is included with each throttle.

Lifetime Limited Warranty: This module comes with our Lifetime Limited Warranty. Please see here for more information.

FAQ

I found a used ETM online. Can I simply swap it into my vehicle?
Sometimes yes, but there is software involved as well as hardware, so just because the hardware matches doesn’t mean the software does. Incorrect software will lead to high idle which can damage the engine over time.

What goes wrong inside the unit?


The photo on the top illustrates potentiometer strips which have been removed from a failed throttle body unit. In this case, both carbon rungs are worn right through. Each time the wier sweeps past these spots, the ETM will switch to “Limp Home” mode. “Limp Home” mode is an emergency software program that allows the vehicle to be driven in case of ETM, or other vital component failure. In this mode you will experience poor engine performance, poor throttle response and the car will not exceed 40MPH. Each ETM contains two separate potentiometers located on either side of the throttle shaft in the plastic end caps. These potentiometers are manufactured on cellulose acetate substrate (similar to camera film) as it is malleable and easily formed into a circle. The two thin carbon layers are then sprayed on this base creating resistive tracks.



Metal wipers travel across these tracks according to the gas pedal position input.ETM-Fault-tracing2-1
The fundamental flaw with this design is that the carbon layer’s chemical composition is not strong enough to withstand continuous wiper friction. As a result, the wiper scrapes off the carbon run right down to the substrate, creating an open circuit that causes the ETM to switch to limp-home mode.

Over the years, the manufacturer tried to correct this problem with wider and thicker runs as well as softer metal wipers. ETM throttles with these modifications were marked with a yellow label instead of the original white. However, since that sensor has to be rolled into a perfect circle there are limits to how thick the carbon can be, otherwise, it will simply crack.
