DTC P0181: Fuel Temperature Sensor A Circuit Range/Performance
WARNING: This page does not describe the selected car, but rather 32 other vehicles, including the 2005 Mercury Sable, 2005 Mercury Mountaineer, 2005 Mercury Monterey, 2005 Mercury Montego, and 2005 Mercury Mariner. However, it is still accessible from the selected car via links, so may be relevant.
P0181 - FUEL TEMPERATURE SENSOR A CIRCUIT RANGE/PERFORMANCE
| Description: | The comprehensive component monitor (CCM) monitors the fuel temperature sensor for acceptable operating temperature. If voltage falls below or exceeds a calibrated limit, for a calibrated amount of time during testing, the test fails. | ||
| Possible Causes: |
|
||
| Diagnostic Aids: | Verify the FRT PID value to determine an open or short. | ||
| Application | Key On Engine Off | Key On Engine Running | Continuous Memory |
