2003 Toyota Echo Question: What causes the water light comes on? What Causes the Engine light to come on?



RAD-WRITER, Hillview, KY, April 12, 2012, 17:03

Water Troubles?
I checked all the fluid levels and the reservoir was down about a liter and a half. I filled it with water as it would have lots of antifreeze in it for this time of the year.
Engine Troubles
I checked the Gas cap and it seems fine.
Where is the Mass Air Flow Sensor and how do I clean it.

    The mass airflow sensor will be located on the air intake. Find your air filter housing and follow it toward the engine. Usually about 6inches to a foot past it. Remove the the bolts holding in with a security (holllow) starhead. Clean with MAF cleaner from a parts store and reinstall. Losing the amount of coolant that you are, I would suggest looking for a leak somewhere. Get the check engine code read at a parts store for free and post that result.
