Delphi AS10283 Ignition Knock (Detonation) Sensor

Ignition Knock Sensor for Toyota and Lexus

Delphi AS10283 is an ignition knock sensor built for direct replacement on a wide range of Toyota and Lexus applications. It uses a single pin terminal, one male connector, and a round connector shape for a straightforward OE-style electrical connection.

With OE development and product validation methods behind it, this Delphi knock sensor is tested and calibrated to OE standards for accurate signal output. That helps maintain proper engine control response on vehicles such as the Toyota Camry, Toyota Tacoma, Lexus ES300, and Lexus RX300.

Detailed Description

Delphi AS10283 is a replacement knock sensor for vehicles that rely on precise detonation detection to help the engine control module adjust timing correctly. This sensor is used across many Toyota and Lexus platforms, including 1994-2006 Toyota Camry, 1995-2004 Toyota Tacoma, 1998-2003 Toyota Sienna, 1994-2003 Lexus ES300, and 1999-2003 Lexus RX300. The AS10283 part number is also cross-referenced with Standard Ignition KS81 for the same application.

Delphi validates these sensors to OE standards so the signal output matches the needs of the original engine management system. That makes AS10283 a practical choice when replacing a failed knock sensor on a Toyota Camry, Lexus GS300, or Toyota Tundra.

Common Problems This Sensor Addresses

• Knock sensor fault codes
• Audible spark knock or pinging under load
• Reduced engine performance from incorrect timing control
• Check engine light related to detonation sensor failure
• Rough operation caused by inaccurate knock detection

Installation Notes and Tips

• Verify connector style, terminal count, and mounting location before installation.
• Inspect the harness and connector for corrosion or damaged pins before replacing the sensor.
• Use the vehicle service procedure for torque and access requirements.
• Confirm application by year, make, and model before ordering; this part is used on many Toyota and Lexus vehicles.

Quality Assurance

Delphi backs this sensor with OE development and product validation methods. Each unit is tested and calibrated to OE standards to support accurate readings and reduce repeat repairs.
