Delphi AS10241 Ignition Knock (Detonation) Sensor

Delphi AS10241 Ignition Knock Sensor

The Delphi AS10241 ignition knock sensor is built for accurate engine knock detection on select BMW applications. It uses OE-level development and validation methods to deliver consistent sensor readings that support proper engine control and help reduce repeat repairs.

Key Features

• Ignition knock (detonation) sensor for emission control and engine management systems
• OE-standard testing and calibration for accurate signal output
• Round connector with 1 connector, 4 terminals, male connector gender, and female terminal gender
• Screw mounting type with pin terminal design
• Length: 315
• Package contents: ignition knock (detonation) sensor
• Cross-reference part numbers include Standard Ignition KS334 and 5S2147

Detailed Description

Delphi AS10241 is an ignition knock sensor engineered for BMW 323Ci, 323i, 325Ci, 325i, 325xi, 328Ci, 328i, 330Ci, 330i, 330xi, 525i, 528i, 530i, X3, X5, Z3, and Z4 applications listed in the fitment data. As a knock sensor, it monitors engine vibration patterns and sends a signal to the engine control system so timing adjustments can be made when detonation is detected. Delphi validates these sensors to OE standards, helping maintain accurate readings across the vehicle range.

This part number, AS10241, is a direct-fit style replacement for many BMW inline-six applications from 1999 through 2006. If you are searching for a BMW knock sensor replacement for 325i, 330i, X5, or Z4 models, AS10241 is the relevant Delphi part number to verify against your original sensor.

What It Helps Address

• Knock or pinging under load
• Check engine light related to knock sensor circuit faults
• Incorrect ignition timing caused by faulty sensor input
• Reduced engine performance from inaccurate detonation detection
• Repeat repairs caused by inconsistent sensor calibration

Installation Notes and Tips

Verify connector shape, terminal count, mounting style, and sensor length against the original part before installation. This sensor uses a screw mounting design and a round 1-connector layout, so matching the OE connector and mounting point is important for proper installation. Inspect the harness and mounting surface for damage or corrosion before replacing the sensor.

Quality Assurance

Delphi sensors are developed and validated using OE-focused methods and tested to OE standards for accurate readings. That level of calibration supports dependable engine management performance on BMW 325Ci, 330Ci, X3, X5, and related applications. Part number AS10241 is built to meet the fitment and signal requirements of the listed vehicles.
