How we calculate scores →About this gear
R17JJ-CCR is the oxygen-cell type specified for the JJ-CCR. The current manual requires this exact type and limits service to 12 months in use, within 15 months of manufacture. Time on a shelf therefore matters when buying a replacement.
Consider before buying
Check the manufacture date and exact marking before accepting stock. The manual explicitly excludes PSR-11-39-JJ as a factory-authorised substitute. A low price is not a useful saving if the remaining permitted life is short; follow the current manual and your training for inspection, calibration and replacement.
Our take
Buy the specified cell from a source that can confirm its identity and date. An older teardown reports favourable impressions of R17JJ-CCR cells, but offers no eligible numeric overall rating or evidence about a particular new batch. We have not verified an authorised alternative, and do not treat a similar-looking oxygen sensor as interchangeable.
