Detailed Description

Standard Ignition PS629 is engineered for vehicles that rely on an engine oil pressure switch to report pressure status to the instrument cluster or warning system. This part is used on applications such as 2018-2020 Chevrolet Traverse, 2018-2020 Chevrolet Impala, 2014-2019 Cadillac XTS, and 2018-2020 Buick Enclave when equipped with oil pressure gauges. It also fits 2021-2024 Buick Enclave, 2021-2023 Chevrolet Traverse, and 2024 Chevrolet Traverse Limited. This part cross-references Standard Motor Products (e.g., PS815, S4629) for the same application.

What It Helps Fix

  • Inaccurate oil pressure gauge readings
  • Oil pressure warning light staying on or not triggering correctly
  • Faulty switch signal to the dashboard or engine monitoring system
  • Intermittent oil pressure indication caused by a worn electrical switch
  • Replacement needs after diagnosing an oil pressure sender or switch fault

Installation Notes and Tips

Verify the engine uses an oil pressure gauge or switch-style sender before ordering. Match the connector style and thread location to the original part, and inspect the harness for corrosion or damaged terminals during installation. Confirm the fault with proper diagnostic testing before replacing the switch.
