Replaced Thermostat, now won't run

Asked by GuruS952B Jul 21, 2020 at 03:46 PM about the 2017 Jeep Cherokee Latitude FWD

Question type: Maintenance & Repair

Was throwing P0128 Thermostat Rationality code. Determined the
thermostat needed replacing. Replaced it, hooked everything back up and
now won't run properly. It now has a misfire in cylinder two, throwing codes
like U1504 Implausible Message Data Length Received from Steering Angle
Sensor, P0222 Throttle Position Sensor 2 Circuit Low, P0108 Manifold
Absolute Pressure Sensor Circuit High, P0340 Camshaft Postion Sensor,
P0198 Engine Oil Temp Sensor, and a bunch off the wall other codes. Not
really sure what to do. Any ideas on what I should try?
