Read the codes like this.
That transmission selector switch may be bad.
If you have the selector in drive then the L should never be lit up.
Found another post with your problem from years ago. No solution tho.
Happens on/off for past 4 months. The shift indicator lite shows both "D"and "L" and will not shift out of first (shifter is in "D").Lite displays "P" and "L" when turning key on, engine not running.Disconnecting the connection to the TPS does not change it either (thoughtit was known TPS issue with Previa's).Goes away after a while by itself and all is fine for a while.Any help appreciated.
And a follow up. Doesn't matter which gear I put it in, it stays in first with the light onthe shift indicator indicating "L" and whatever gear I actually select(P,R,D,or 2), kinda shows that its in 2 gears at the same time.With just the key on "acc" (engine off)it also does this.Once, I was checking the connections to the ECM when this occurred and itwent away for a couple weeks.I thought I narrowed it down to either the wiring to the TPS or the ECMitself.
This car is old and that selector switch is simple. Nothing should be lighting that unless there is internal switch problems.
You must have an o2 sensor behind the catalytic converter. What it does is tell the engine computer how the cat is working. No relation to the transmission shifting. The oil level light is referring to the oil level. Did it stop doing that?
10 is starter signal. You can do this instead of the battery.
Is this what you mean by blinking codes.
Don't forget to rate me.
Does this blinking only happen when you do the jumping of the TE1 to E1. In the diagnostic socket.
I think you are having fun with that.
I would price a new or used trans selector switch they do go bad.
