P0181 - FUEL TEMPERATURE SENSOR A CIRCUIT RANGE/PERFORMANCE
| Description: | The powertrain control module (PCM) continuously monitors the fuel rail temperature (FRT) sensor input to determine if the FRT signal is within an expected range. The test fails when the fuel temperature falls below or exceeds a minimum or maximum calibrated value for a calibrated period of time. | |||
| Possible Causes: |
|
|||
| Diagnostic Aids: | Monitor the FRT voltage and temperature PIDs on a scan tool to isolate open or short circuit from the system concern. Repair any FRT circuit related DTCs first. | |||
| Application | Key On Engine Off | Key On Engine Running | Continuous Memory | |
