DTC P025B-00 PCM (SKYACTIV-G 2.5T) DETECTION CONDITION AND POSSIBLE CAUSE

DTC P025B-00	FUEL PUMP CONTROL MODULE CIRCUIT RANGE/PERFORMANCE PROBLEM
DETECTION CONDITION	When any of the following conditions is met: PCM detects overheating in fuel pump control module. Output duty ratio signal received from PCM is in error. Temperature detection thermistor in fuel pump control module is malfunctioning. Output signal from fuel pump control module is erratic (noise overlap). Diagnostic support note This is a continuous monitor (CCM). The check engine light does not illuminate. FREEZE FRAME DATA is not available. Snapshot data is available. DTC is stored in the PCM memory.
FAIL-SAFE FUNCTION	Stops fuel pump control. (If overheating is detected in fuel pump control module)
POSSIBLE CAUSE	Fuel pump control module connector or terminals malfunction PCM connector or terminals malfunction Short to ground in wiring harness between fuel pump control module terminal 1B and PCM terminal 2AP Short to power supply in wiring harness between fuel pump control module terminal 1B and PCM terminal 2AP Open circuit in wiring harness between fuel pump control module terminal 1B and PCM terminal 2AP Fuel pump control module malfunction PCM malfunction
