P2515
A/C Refrigerant Pressure Sensor B Circuit
Moderate severity
What it means
General electrical fault in the second A/C refrigerant pressure sensor circuit. Sensor B usually monitors the low-side or compressor-suction pressure (in addition to high-side sensor A). The ECM cannot read a plausible value and disables variable compressor control to avoid evaporator freeze-up or overpressure.
Is it safe to drive?

The vehicle is usually drivable for short distances, but the problem can worsen or affect emissions. Diagnose and repair as soon as practical.
