Quick answer
For the 2022 Chevrolet Bolt EV and Bolt EUV in the US, the supplied evidence associates P018B with a manufacturer communication about diesel-fuel cold-weather gelling. That evidence does not establish a Bolt-specific meaning, symptom, cause, driving decision, charging decision, or repair for P018B.
This page separates verified manufacturer/regulator evidence from supporting material. Unsupported causes, repairs or safety conclusions are not guessed.

1. What does P018B mean?
For the 2022 Chevrolet Bolt EV and Bolt EUV in the US, the supplied evidence associates P018B with a manufacturer communication about diesel-fuel cold-weather gelling. That evidence does not establish a Bolt-specific meaning, symptom, cause, driving decision, charging decision, or repair for P018B.
2. Technical explanation
The supplied NHTSA manufacturer communication, 18NA103, lists P018B as “Fuel Pressure Sensor Performance” alongside diesel-engine fuel-system codes including P0087, P228A, P228B, and P2635. Its described condition is diesel fuel that may gel or develop solids in cold ambient temperatures and restrict an in-tank fuel-pump pickup. The communication advises bringing the vehicle inside so diesel fuel can warm above 0°C (32°F). The supplied evidence does not establish that this diesel-fuel guidance applies to the battery-electric 2022 Chevrolet Bolt EV or Bolt EUV.
3. What system is affected?
Not yet established by verified evidence for the 2022 Chevrolet Bolt EV or Bolt EUV. The cited communication concerns a diesel fuel system and engine-control module.
4. How serious is this code?
Not yet established by verified evidence for the listed Bolt vehicles.
5. Symptoms you may notice
- Not yet established by verified evidence for the 2022 Chevrolet Bolt EV or Bolt EUV.
- In the cited diesel communication, the described condition may prevent the engine from starting after cold-temperature fuel gelling or solids restrict the in-tank fuel-pump pickup.
6. Possible causes
- Not yet established by verified evidence for the 2022 Chevrolet Bolt EV or Bolt EUV.
- For the diesel vehicles addressed by NHTSA communication 18NA103, the stated cause is diesel fuel blends incompatible with cold ambient temperatures, which may gel and/or develop solids that block the in-tank fuel-pump pickup.
7. Can I still drive the vehicle?
Not yet established by verified evidence for the 2022 Chevrolet Bolt EV or Bolt EUV.
8. Can I charge the vehicle?
Not yet established by verified evidence for the 2022 Chevrolet Bolt EV or Bolt EUV.
9. What you can safely do
- Do not assume the diesel-fuel instructions in NHTSA communication 18NA103 apply to a battery-electric Bolt EV or Bolt EUV.
- Have the displayed diagnostic information verified using appropriate Chevrolet service information or a qualified Chevrolet service provider.
10. Step-by-step troubleshooting
- Confirm the exact diagnostic code and the vehicle identification details, because the supplied evidence does not demonstrate a Bolt-specific P018B diagnosis.
- For diesel vehicles covered by communication 18NA103 only, the communication states to bring the vehicle indoors and allow diesel fuel to warm above 0°C (32°F), then confirm that the engine starts.
11. When to contact service
Contact a Chevrolet dealer or qualified service provider to verify the code and its applicability to the specific vehicle. The supplied evidence does not provide Bolt-specific service direction.
12. What the service center may check
- Not yet established by verified evidence for the 2022 Chevrolet Bolt EV or Bolt EUV.
- For the diesel condition in communication 18NA103, the cited text directs technicians to allow the fuel to warm above 0°C (32°F) and confirm that the engine starts.
13. Possible repair or resolution
- Not yet established by verified evidence for the 2022 Chevrolet Bolt EV or Bolt EUV.
- For the diesel condition cited in communication 18NA103, the provided evidence identifies warming the fuel above 0°C (32°F) and confirming engine start; it does not provide a Bolt-specific repair resolution.
