Evora tpms replacement

[maxj0]

Hi, 

 

I need to replace one of the TPMS sensors on one of my 2009 evora wheels after a major corrosion issue meant it fell apart during a routine tyre change. In fact I’m wondering if it might be time to replace all of them. Has anyone found a realistic alternative to the standard Lotus items or a cheaper place to source them?

 

thanks,

 

Max

All In-tyre TPMS sensors, with an integral battery, have a finite service life - and should be periodically changed as a complete assembly.  Outside of changing a single sensor due to unexpected failure, it follows that they would be routinely changed, as a set, when changing worn tyres.

Doesn’t your owners handbook offer any guidance as to the anticipated service life prior to expected replacement?  If your sensors are the original fit, they’ll now be over ten years old - and likely well past their expected lifespan.

As for sourcing a non-Lotus component, you may need to consider that the sensor/transmitter is paired with the corresponding in-car receiver module.  You might expect to find the OEM Manufacturer part number marked on the sensor - if so, armed with this information, you might be able to source via an alternative supplier or motor factor.

You can buy individual ones from lotus via Deroure but they are not cheap, or from ebay. There was a recent thread on The Lotus Forum and here is one response:

Much cheaper to buy a set of Autel sensors and programmer pad.  The Lotus system on the Evora uses 433Mhz and the sensors need to be programmed with an ID number and system will detect the sensors and learn which sensor is where after driving for a few miles.  The sensors do need an ID programmed in the first place so you can't use the Autel sensors straight of the shelf.  The Autel programmer should be able to clone your existing sensors if you want to keep the ID the same but as long as the sensor is programmed with an ID the system will self learn.

Set of 4 sensors are available for around £80-90 and the USB programming pad is available for around £40-60.   Here are just one link out of many from Ebay also many sellers on Amazon selling both Autel sensors and programmers.

Autel MX sensor 433Mhx £80 for 4: https://www.ebay.co.uk/itm/X4-Original-Autel-MX-Sensor-433MHz-Programmable-Universal-TPMS-Sensor-Most-Cars/183264912039?epid=1342402954&hash=item2aab70a2a7:g:d38AAOSwi3tbIjHt

Another source is from the following, but I think this could be a couple of years old and I haven't needed to use then as my sensors are still ok on my 2010 Evora :

TYR- S002-T-Pro Clamp – In Sensor Part No: HTS-A122B, 72-20-364
Tel: 0116 2001020
Unit C Whiteacres, Cambridge Rd, Whetstone, Leicester, LE8 6ZG                          £36 approx

I think the actual make is: Schrader   TPMS Part No. 13227143
