Hi All

I'm getting this error when driving on highway around 60 in 5th. I've checked and so far can be multiple issues but don't which one is more accurate.

So far I have EGR issue. Rich Mix or engine coolant sensor. Don't want to mess it up by doing everything I found on the web so any help will be appreciated, my thinks leads me to coolant sensor first but don't know where is located.

Celica is 94 1.8l

More than likely that coolant sensor will be at the neck where the coolant goes into the engine block or it can be before the thermostat at the side where the coolant exits the engine. Easiest way to find it would be to follow your top and bottom hose from the radiator to the block. Shouldn't be hard to miss a sensor with wires connected to it. Lol.
