Your ETM is also covered by our Lifetime Limited Warranty.
When you buy from XeMODeX, you are buying a proven, quality product that stands the test of time.

xemodex_guaranteePlug and Play installation. Your ETM will not require any software reload. No matter if the sticker is yellow or white.

xemodex_guaranteeThe ETM is shipped with a full test report that includes diagnostic trouble codes, software numbers and potentiometer graph.

xemodex_guaranteeBrand new original gasket is included with every ETM shipment.


xemodex_guaranteeImportant: A failing MAF could cause erratic idle, lack of power and stalling, and on many occasions it will not post the diagnostic trouble codes. We recommend that you replace this part whenever the ETM is replaced, even if the MAF appears to be working properly.

Your ETM will not require any software reload. No matter if the sticker is yellow or white.

CONTACT-LESS PROGRAMMABLE DUAL SENSOR TPS UPGRADE

Zero wear Hall-Effect dual Throttle Position Sensor, design 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 are programming each sensor on the actual ETM ensuring that the maximum deviation between the two sensors is less than 1.5 degrees. F.Y.I. Maximum allowed deviation in the original throttle is 14 degrees before the software triggers the TPS sensor fault codes.

BRAND NEW STAINLESS- STEEL BEARINGS

Brand new steel bearings are upgraded to stainless steel material to better withstand corrosion.

MANUFACTURED 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.

ETM-Fault-tracing2
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.

ETM-Fault-tracing2
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 which 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.
