What is code p0118 in a 2003 Chrysler Sebring?

Code P0118 in a 2003 Chrysler Sebring indicates a problem with the engine coolant temperature (ECT) sensor. This code is triggered when the engine control module (ECM) detects a voltage reading from the ECT sensor that is higher than the expected range, suggesting a potential short circuit or a faulty sensor. It can lead to issues such as poor engine performance or increased emissions. To resolve this, it is recommended to inspect the sensor and its wiring for damage or corrosion.
