HONDA CR-V — What to know
The CR-V is one of America's best-selling SUVs and has excellent long-term reliability. The 1.5T turbocharged four-cylinder (2017–2021) was subject to a documented oil dilution issue in cold weather — Honda extended the warranty on affected vehicles.
Specifically for oil pressure sensor replacement on this model:
The 1.5T CR-V (2017–2021) had widespread reports of gasoline diluting engine oil in cold climates — the most significant Honda reliability issue of recent years. Honda extended the powertrain warranty on affected VINs and updated engine calibration. In cold states, verify this has been addressed. The 2022+ CR-V with the improved 1.5T does not have this issue.
What is this repair?
Plain-English overview
Engine management sensors monitor key parameters—knock, coolant temperature, oil pressure and more—so the ECU can protect the engine and optimise performance. A faulty sensor typically triggers a check engine light and may cause the ECU to adopt a conservative safe mode.

- Check engine light with a sensor-specific fault code
- Engine running in a reduced-power or safe mode
