Innovate MTX-L E8 code
 

Just a quick question for those more knowledgeable on the subject then I am.
I've read the existing threads and this question is not listed there.

Can car storage affect the sensor?
I know my sensor is now dead, when I first started up the miata after winter storage on sunday, it had a hard time starting and the sensor went to E8 right away.
Could the very cold winter temperatures have affected the sensor even though it wasn't powered during that time?
The sensor was reading accurately and correctly before the car was put away for winter.
Could it also be the fuel stabilizer causing issues with the sensor upon startup?

I'm just having a hard time seeing why the sensor would die on it's own over winter.

Thanks!

I get E-8's quite often on my LC2. Most of the time I can recalibrate and then it will go away for awhile. Eventually I have to replace the sensor.

After the car has been sitting with the engine off, no exhaust fumes lingering in the pipes, unplug the sensor, turn ignition on but do not start the engine. Wait 30 seconds, shut ignition off. Plug sensor back in, turn ignition on. Wait till the warmup is cycle complete, green LED on the controller stays solid, and the AFR shows 22.4 and you should be good to go.

Sorry, I guess I should of clarified.
I attempted three times to calibrate. After the CAL screen is on for a bit, it switched automatically to E8.

Ah ok. I'd say go to your local autozone and buy a new sensor, they are about $55. Most of the time when I need to replace mine, I can get them to warranty it out. Part number is 17014 for the old 4.2 Bosch sensor. If it is the newer 4.9 sensor, I'm not sure what the part number is.

Switched to the newer sensor. Being in Canada means no AutoZone and 89$ cad for a replacement from Amazon.
The newer 4.9 sensor is a Bosch 17025.
The old 4.2 sensor is Bosch 17014.

The MTX-L is compatible with both, you just need to change a setting in the program.

I've found all that info on MT.net, just didn't find an answer to the question above...
