- A/C compressor not engaging
- Check engine light on
- Higher than normal engine temperature during A/C use
What Causes P2515? (Most Likely First)
- Failed A/C refrigerant pressure sensor Very High
- Wiring issue in pressure sensor circuit High
- Low refrigerant charge affecting sensor reading Moderate
- ECM A/C control circuit problem Low
Can I Still Drive with P2515?
Yes, but fix soon. P2515 is rated moderate severity. It is not an immediate stop-driving fault, but it will not clear itself — book the repair rather than ignoring the light.
Frequently Asked Questions
Can I still drive with P2515?
Yes, but your A/C may not function properly. The vehicle is safe to drive; you just may not have cooling.
Is low refrigerant the cause of P2515?
Low refrigerant can trigger this code, but P2515 specifically points to the pressure sensor circuit. Both refrigerant level and sensor should be checked.
How much does an A/C pressure sensor cost?
The sensor itself typically costs $30 to $80. With labor to diagnose and replace, expect $100 to $400 total.
