Circuit Description

The HOT light or the LOW COOLANT light will illuminate if DTC P0217 or P0218 is present. The light will illuminate and stay on steady for either of these conditions. If PCM detects a low coolant condition (P1620) the light will flash as opposed to staying on steady.

DTC P0217 will set if engine coolant temperature is greater than 244°F (118°C), no other ECT related DTC(s) are present.

DTC P0218 will set if transaxle fluid temperature is greater than 284°F (140°C), actuator temperature is greater than 320°F (160°C) as calculated by PCM from fluid temperature and actuator on time and if no other transaxle temperature related DTC(s) are present.
