P0218-High Temperature Operation Activated

WARNING: This page is about a different car, the 2005 Jeep Liberty. However, it is still accessible from the selected car via links, so may be relevant.

When Monitored: Whenever the engine is running.

Set Condition: This DTC is an informational code and does not necessarily indicate that a failure exists. It merely flags the fact that trans sump oil temperature reached 116°C or 240F. This temperature level can be reached when operating under heavy load in hot weather. This causes the transmission controller to use an "overheat" shift schedule, which changes the shift patterns in an attempt to control the temperature. Customers may notice a different feeling or response under these conditions. The Owner's Manual includes an explanation of this "Over Temperature Mode" for the customer's information. The DTC sets immediately when the Overheat shift schedule is activated with a Transmission Oil Temperature above 116°C or 240°F.
