What does this mean? - Cars & Trucks

Where is nin Sensor located in 1az engine sienta

That means low coolant level. Some extra info; yellow means a problem is starting to arise, red means there is a problem that needs to be fixed as soon as you can, red flashing means something is about to fail and you shouldn't be driving it unless absolutely necessary, and lastly blue or green are just letting you know a system is functioning properly.

(copied from 'yep it broke' in another question)
A means oil and filter change
1 means tire rotation and
2 means replace engine air filter and cabin air filter
6 means replace VTM4 rear-differential fluid

The P0670 means "Glow Plug Module Control Circuit"
The P0195 means "Engine Oil Temperature Sensor"
The P0184 means "Fuel Temperature Sensor A Circuit Internittent
The P0383 means "Reserved by SAE J2012
The P0579 means "Cruise Control Multi-Function Input "A" Circuit Range/Performance
Hope that can help you!
