I have a 06 Elise in the US that popped two codes today. They are P2127 and P2106. Anyone have any ideas what they are and how to handle them? Thanks for your help. Lonnie

Those aren't Lotus-specific, so google is your friend.

P2127 is Throttle position sensor voltage low.
P2106 is Throttle actuator control system Forced limited power

They both indicate a problem with the drive-by-wire system. Did you notice any change in the car's performance? I would expect reduced power and lack of response to throttle.

No, Pengineer91 there did not seem to be any change. The car only has 15K miles on it, so it should not be a wear issue. It happened on start up after filling up that why I thought that the light was related to the gas cap. I wonder if it was just a fluke. She is getting new tires so I can't check again til I get her back. Has any of yall had that code? Thanks, Lonnie

Do you have a data system tapped into your throttle pedal or throttle butterfly? If you do any it wasn't wired well it can cause these intermittent issues.

If not, clear the codes and see if they come back? Unplug and replug them both as well.

This post might help as it points to wiring diagram on the BOE site.

I also remember seeing a problem where it is possible for the motor in the throttle body to come loose. The throttle body comes apart pretty easily in the car to check. I took mine apart and put lock Tite on the bolts as a preventative measure. Can't remember what codes come up if this happens.

Thanks for the help. A quick update; we cleared the code and it did not come back on. Car ran great at all times. Thanks again for all of the help. Love being part of the Lotus family. Lonnie
