Why it happens

Likely root causes behind P2148

Solenoid winding short or open circuit after heat-cycle fatigue.
ECU pin or harness short to ground or supply.
Low-pressure gear pump wear sends metal debris into high-tolerance pump elements.
Mechanical pusher wear, nozzle clogging or valve gap outside range.
Open circuit at ECU pins or pump connector.
Short to ground in the harness.
Pump-unit internal leak or weak hot solenoid.
Cylinder 2 nozzle clogging from fuel contamination.
