2007 grand Cherokee Laredo. codes P 2181, p0128, and u 1402. Everything seems to point to engine temp issues. It was running cold at the first line of temp. I checked the thermostat and it is working. Upon placing it back in the temp is running normal now. But I have theses codes still. And the heat is not as hot as it was. Any ideas?
