P1454 Honda Code - Fuel Tank Pressure Sensor Range/Performance Problem
Quick Answer
The fuel tank pressure is about 0 kPa (0 in.Hg, 0 mmHg) when starting a cold engine. Common causes include Faulty Fuel Tank Pressure (FTP) Sensor, Fuel Tank Pressure Sensor harness is open or shorted, Fuel Tank Pressure Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P1454 Honda Description
However, if the FTP sensor output when starting the engine is a prescribed negative value or less (excessive negative pressure is detected), the malfunction judgment should be done as follows because it is difficult to distinguish the FTP sensor zero point shift (P1454) from the EVAP canister vent shut valve failure (P2422).
1. If either Temporary DTC P1454 or P2422 is not stored, the PCM stores both DTCs.
2. If both P1454 and P2422 Temporary DTCs are stored and an excessive negative pressure is detected, both P1454 and P2422 DTCs are stored.
3. If either Temporary DTC P1454 or P2422 is stored and an excessive negative pressure is detected, the PCM stores the DTC of the temporary DTC that was stored.
What are the Possible Causes of the DTC P1454 Honda?
- Faulty Fuel Tank Pressure (FTP) Sensor
- Fuel Tank Pressure Sensor harness is open or shorted
- Fuel Tank Pressure Sensor circuit poor electrical connection
