★ Top Answer
The p1217 INFINITI code indicates a problem with the engine coolant temperature rising to a dangerously high level, likely due to a faulty thermostat. The thermostat is located in the thermostat housing along the lower coolant line and is responsible for monitoring the coolant temperature to determine the engine's operating temperature. If the thermostat malfunctions, it can lead to engine overheating, causing potential damage to the car. Overheating can result in the head gasket warping or cracking, requiring expensive repairs in the future. If your check engine light indicates a faulty thermostat, it is important to address the issue promptly. A full replacement costs around $200, so it's best not to delay the fix.
