Diagnostic Test

WARNING: This page is about a different car, the 2009 Dodge Caliber. However, it is still accessible from the selected car via links, so may be relevant.

DTC IS ACTIVE
NOTE: If this DTC sets intermittently, it is possible that the controller is overheating in extremely hot temperatures. This is considered a normal protection operation. No repair is necessary.

NOTE: Low battery voltage can cause excessive current draw in very hot and cold ambient temperatures. Make sure the battery can pass a load test before continuing. Review Freeze Frame information to determine the ambient temperature when the DTC set.

NOTE: This DTC may be set by other DTCs. If P2119 is set with no other DTCs, this does not indicate a faulty Throttle Body.

NOTE: Diagnose and repair any Throttle Position sensor, system voltage, or 5-Volt supply DTCs before continuing with this test.

NOTE: Engine coolant temperature must be between 5°C (41°F) and 110°C (230°F), intake air temperature must be greater than 5°C (41°F), and battery voltage must be greater than 10 volts when performing the ETC Relearn function. If these parameters are not met during the relearn process, this DTC may set.

NOTE: Engine coolant temperature must be between 5°C (41°F) and 110°C (230°F), intake air temperature must be greater than 5°C (41°F), and battery voltage must be greater than 10 volts when programming the PCM. If these parameters are not met during the reprogram process, this DTC may set.
1. Start the engine and allow it to reach normal operating temperature.
  WARNING: When the engine is operating, do not stand in direct line with the fan. Do not put your hands near the pulleys, belts or fan. Do not wear loose clothing. Failure to follow these instructions may result in possible serious or fatal injury.
