The light has come on about 4-5 times.A couple of times right in the driveway even before the transmission has gotten warm. If I unplug a wiring harness that comes up from the transmission to the top of the air filter the light will go out and the car will run at an idle. I can put the car in drive and it will move, but it will not accelerate.
Id guess the oil temp sensor is faulty
or the wire leading to it is corroded
start there
SOURCE: When do I change the transmission fluid in my 2003 Highlander?
If the fluid smells burnt or is black, replace fluid. Manufacturer suggests that you inspect it at every 30,000 mile interval. I would suggest having it flushed every 75,000 miles as a normal maintenence.

Check the timing and compression of the engine. It sounds like you either have a blown head gasket or a the timing jumped.

SOURCE: 2003 toyota highlander. when starting it wont maintain idle.
Try to adjust the idle of the truck because there is a possibility the idle is low and if still not work put the gear in neutral and then start it and step on the gas pedals for 20 sec.

Have patience and light will go off. Or you can go to advance auto to clear it for you. Or you can disconnect the battery for 10 seconds. Your choice.
