DTC P2455-00: GPF Pressure Sensor: High Input

P2455: 00 (PCM (H3T)) DETECTION CONDITION AND POSSIBLE CAUSE

System malfunction location	GPF pressure sensor: High input
Detection condition	When the following monitoring conditions are voltage of GPF pressure sensor exceeds the reference value continues for the set time when the following monitoring conditions are satisfied. Battery voltage: 8 V or more GPF pressure sensor monitor basic condition are met GPF pressure sensor estimated temperature: Exceeds 20°C {68°F} The following DTCs are not detected: ECT sensor No. 1: P0116: 00, P0117: 00 and P0118: 00 IAT Sensor: P0110: 00 MAF Sensor: U063F: 00
Fail-safe	Inhibits the automatic GPF regeneration control. Inhibits the compulsory GPF regeneration control. Inhibits the fuel cut control.
Possible cause	Malfunction in wiring harness (including connector/terminal) between GPF pressure sensor and PCM. (See CIRCUIT INSPECTION .) (See CONNECTOR INSPECTION .) GPF pressure sensor malfunction (Refer to [ GPF PRESSURE SENSOR INSPECTION] in service information). PCM malfunction (Refer to [PCM REMOVAL/INSTALLATION ] in service information).
Repeatability verification procedure	Clear the DTC recorded in the memory. (See CLEARING DTC .) Perform the KOEO or KOER self-test. (See DTC INSPECTION .)
