- Any combination of DTCs P0300, P0171, P0174, P228C may be set.
2Finding the cause
Possible causes
- Because of a surplus of winter grade fuel in storage, the EPA is waiving the fuel vapor requirement, which extends the use of winter fuel into the summer months.
- The use of winter fuel in summer weather may cause drivability concerns.
Steps to confirm (in the document’s order)
- These should not be single events but multiple occurrences associated with hot days.
3Correction
Caution
- No repair is required; the vehicles are not damaged and will recover.
- There is no other remedy until summer fuel and/or cooler weather is available.

- Remedy
- This Preliminary information communicates the use of Winter grade fuel during the warm months of 2020 and the potential rivability issues that it can cause. The ongoing Coronavirus (COVID-19) pandemic has caused significant reductions in driving and fuel use. Due to the surplus of winter grade fuel sitting in storage (pipelines/stations) the EPA is waiving the fuel vapor requirement. This will extend the use of winter fuel into the summer months. The drivability concerns should not be single events but should be multiple occurrences associated with hot days.
