I need help trying to fix this issue. Just changed coolant temp sensor and alternator. Ran and drove fine yesterday several on and offs with plenty of cool down time in-between. Coolant temp sensor is the only code being thrown in again but checked the sensor before install and it read temps properly according to resistance readings. Any tips or ideas? According to the wiring diagram the power wire going into the coolant temp sens splits to I believe 3 sensors but the others show fine (no dtcs) for anything other than the coolant temp sensor
