Quick answer

For a 2019 Chevrolet Bolt EV in the US, DTC P2517 is identified in a GM/NHTSA manufacturer communication as “Air Conditioning (A/C) Refrigerant Low Side Pressure Sensor Circuit Low Voltage.” The communication concerns reports of inoperative A/C or A/C that is low and does not blow cold. GM Engineering was still determining the root cause.

This page separates verified manufacturer/regulator evidence from supporting material. Unsupported causes, repairs or safety conclusions are not guessed.

1. What does P2517 mean?

For a 2019 Chevrolet Bolt EV in the US, DTC P2517 is identified in a GM/NHTSA manufacturer communication as “Air Conditioning (A/C) Refrigerant Low Side Pressure Sensor Circuit Low Voltage.” The communication concerns reports of inoperative A/C or A/C that is low and does not blow cold. GM Engineering was still determining the root cause.

2. Technical explanation

The verified manufacturer communication, PIE0543 (published October 9, 2019), lists P2517 among DTCs that may be found when the A/C is inoperative or does not blow cold. It defines P2517 as an A/C refrigerant low-side pressure sensor circuit low-voltage condition. The same communication also lists P0534 and P0071 as possible accompanying codes. GM Engineering requested information from affected vehicles before repair because the root cause was under investigation.

3. What system is affected?

Air-conditioning system; specifically, the A/C refrigerant low-side pressure sensor circuit.

4. How serious is this code?

Not yet established by verified evidence.

5. Symptoms you may notice

  • A/C may be inoperative.
  • A/C may be low and may not blow cold.

6. Possible causes

  • GM Engineering was attempting to determine the root cause. No specific cause is established by the verified evidence.

7. Can I still drive the vehicle?

Not yet established by verified evidence.

8. Can I charge the vehicle?

Not yet established by verified evidence.

9. What you can safely do

  • If the vehicle was brought in for an A/C concern, have the condition evaluated by a qualified Chevrolet service facility.
  • Do not assume that a specific component or refrigerant condition is the confirmed cause based on P2517 alone.

10. Step-by-step troubleshooting

  1. The verified communication states that GM Engineering needed information gathered from vehicles exhibiting this condition before repair.
  2. No detailed diagnostic test sequence is established by the supplied verified evidence.

11. When to contact service

Contact a Chevrolet service facility if the A/C is inoperative or is not blowing cold and P2517 is present.

12. What the service center may check

  • Confirm whether P2517 is stored.
  • Assess the reported A/C concern, such as inoperative A/C or insufficient cooling.
  • Follow applicable manufacturer information-gathering procedures before repair when the condition is present; the supplied communication states this information was needed by GM Engineering.

13. Possible repair or resolution

  • Not yet established by verified evidence. The supplied communication states that GM Engineering was determining the root cause and requested vehicle information before repair.
