DTC Description
OBD STATUS
P1454 FTP Sensor Circuit Range/Performance Problem
Does the HDS indicate FAILED?
YES
The failure is duplicated. Go to step 3.
NO
If the HDS indicates PASSED, there might be an intermittent failure, and the system is OK at this time. Check the on-board snapshot, and repeat the driving conditions when the DTC set (fuel level, engine speed, vehicle speed, and outside air temperature). If no problem is found, check for poor connections or loose terminals between the FTP sensor and the PCM. Also check for a blockage in the FTP sensor vent port and vent hose, and the EVAP canister vent hose and drain joint. If the HDS indicates NOT COMPLETED, let the engine idle until a result comes on.?
