Chrysler Sebring engine warning light persists after thermostat replacement on Chrysler Sebring

Some Chrysler Sebring owners report experiencing a persistent engine warning light even after replacing the thermostat. This issue may be related to low coolant levels, which can manifest through symptoms like erratic heat and a temperature gauge reading at 9 o'clock. Additionally, some owners find that the Powertrain Control Module (PCM) may require time or mileage to reset the check engine light after resolving the initial problem. If the warning light continues, it is advisable to seek a thorough diagnosis from a Chrysler service, as it could indicate underlying issues. Potential causes for the persistent light include overheating conditions detected by the coolant sensor, which might stem from a defective sensor, radiator blockage, malfunctioning fans, or internal engine problems. Furthermore, the presence of specific trouble codes, such as P1217, can provide valuable insights into the issues triggering the warning light, highlighting the importance of addressing these codes to resolve the concern effectively.
