Pretty sure her 07 does not have the gear indicator on the dash. She says she never had one.

Cleared the codes, started the car, cycled through the gears, rescanned and there was the code pending again.

I'm assuming the problem is with that thing on the transmission. Does anybody know its actual name so I can replace it? Seems pretty straight foreword and easy.

Anything else it might be before we start throwing money at it?

That does sound familiar with the 07's not having the gear displayed (08+ definitely does though).

The switch on the tranny that the shifter drives is the Switch Assy, Neutral Start (84540-46010). Although the name doesn't imply it, it feeds all of the gear positions to the ECM.

Any recommendations on where to buy this part? I am finding prices anywhere from 40 - 350.

I have recently changed out my battery and alternator on a 2011 Yaris with automatic transmission and 82K miles. After I did that the CEL continued to come on after a couple of drives. The code that came up is P0705 and now the gears do not show up in the display.

I have checked all fuses and none have blown, including the 10A GAUGE fuse under the bottom of the dash. Since changing out the alternator and battery everything has been running great. The only issue is the CEL coming on and I am unable to see what gear I am in. Other than that, the engine continues to shift fine. I have also checked all connections and they are clean and firmly attached.

Thanks for any input.

$350 is dealer list and is crazy expensive for the part. If you can find one for as little as $40, go for it. Someone else with the same issue took theirs apart and cleaned the corroded contacts.

I finally got the Switch Assy, Neutral Start (84540-46010) in and am in the process of replacing now. Here is the problem:

I got the old switch off, it was on there really good and I needed to pry it off. Now when I go to put the new one on it is just as tight if not tighter. I have cleaned the rod coming out of the transmission where it slides on and have separated the opening as wide as possible on the switch. Any ideas on how to get it back on? No room to get good whacks with a hammer. I had to use a little pry bar and hammer to get the old one off.
