Detailed Description

Delphi SS12377 is engineered for vehicles that depend on precise crankshaft position data for ignition timing, fuel delivery, and engine control. Delphi validates and calibrates its sensors to OE standards, helping ensure accurate readings and dependable signal transfer. This part cross-references Standard Ignition PC1197 for the same application. Compatible BMW and Mini coverage includes models such as the 2020-2023 BMW 330i, 2021-2023 BMW M3, and 2019-2023 BMW X5, along with select Mini Cooper applications. The part number SS12377 is also useful when matching an OE-style replacement by connector shape, terminal count, and sensor design.

What It Helps Address

• Crankshaft position sensor fault codes
• Intermittent no-start or hard-start conditions
• Rough idle or stalling related to incorrect engine speed input
• Misfire or timing-related drivability concerns
• Loss of accurate crank signal to the engine control module

Installation Notes and Tips

Verify connector shape, terminal count, and mounting location before installation. This sensor uses a 1-piece electrical connector with 3 terminals and does not include a wiring harness or mounting bracket. Confirm vehicle application by year, make, and model before ordering. For fitment examples, this part fits 2020-2023 BMW 330i, 2021-2023 BMW M3, 2019-2023 BMW X5, 2022-2023 BMW 230i, and 2022-2023 Mini Cooper.

Quality Assurance

Delphi sensors are developed and validated using OE-focused testing methods and calibrated to OE standards for accurate signal output. That process supports consistent performance and helps reduce repeat repairs.
