Pin Assignment Reference (3-Pin Sensor)

1928405523 vs 1 928 405 523 – Same Part, Two Formats

Both 1928405523 and 1 928 405 523 refer to the identical Delphi connector. The spaced format (1 928 405 523) is the standard Delphi/Bosch part number notation used in OEM catalogues; the continuous format (1928405523) is commonly used in aftermarket search queries. Both formats are interchangeable when ordering.

Delphi 192840xxxx Series – Application Range

The Delphi 192840xxxx series covers waterproof connectors from 1-pin to 12-pin used across GM, Ford, VW, Opel/Vauxhall, and Renault platforms. The last four digits identify the specific pin count and housing variant. This series is also cross-referenced with Bosch connector part numbers on some European platforms.

Diagnosis – Common Faults

• Intermittent sensor codes after rain: Inspect wire seal integrity – moisture ingress causes intermittent open-circuit faults
• P0100–P0118 (MAF/ECT Circuit): Check connector before replacing sensor – a corroded Delphi connector is a common root cause on GM and VW platforms

FAQ

Q: Is 1928405523 a Delphi or Bosch part number?
