Question about 2003 BMW 525i
Check engine light is on code comes up p1112 engine coolant temp. radiator sensor hi input how do I fix it
First, find the sensor. Bottom passenger side of radiator I believe. If you're lazy, just change the sensor and make sure the connector is good and tight. If not, do resistance checks on the disconnected sensor and voltage on the connected sensor, both cold and hot. The results will tell you the problem.
If the connector is loose or broken, you can get one with pigtails at your local auto parts store. Chop the old one off, splice the new one in, close up surgery, and connect.

When they start the inspection, the states computer
will read that codes have been recently deleted. This
will get you an automatic rejection. I know it will in mass. I would stop by an inspection station and ask
if your engine temp. can keep you from passing.
But if you wan't to clear the codes. Go by an autozone/napa or advance auto parts. They will clear
the code for free. Hope this helps. Good luck.
