98822-1031 vs 988221031 – Same Part, Two Formats

Both 98822-1031 and 988221031 refer to the identical connector. The hyphenated format (98822-1031) is the standard OEM part number notation; the continuous format (988221031) is commonly used in aftermarket catalogues and search queries. Both formats are interchangeable when ordering.

Unsealed Connector – Installation Notes

This is an unsealed connector. Do not install in exterior, underbody, or moisture-exposed locations. For wet-environment applications, use a sealed IP67/IP68 equivalent. Installing an unsealed connector in a wet location will cause terminal corrosion and intermittent signal faults.

Diagnosis – Common Faults

• Intermittent sensor fault codes: Inspect terminal contact pressure – unsealed connectors are prone to terminal spread from repeated mating cycles
• High contact resistance: Measure with milliohm meter; >0.5Ω indicates terminal wear or oxidation – replace connector assembly
