Detailed Product Overview

This Delphi knock sensor, part number AS10334, is designed for vehicles that rely on precise detonation monitoring to manage spark timing and engine performance. It is a strong match for drivers searching for a Toyota Tundra knock sensor, Toyota Sequoia knock sensor, or Lexus LX470 knock sensor replacement with OE-style signal accuracy. Delphi validates and calibrates its sensors to OE standards, helping ensure the engine control system receives the correct input from the knock sensor circuit.

Compatible With 2000-2005 Lexus LX470, 2000-2005 Toyota Land Cruiser, 2003-2004 Lexus GX470, 2001-2004 Toyota Sequoia, 2001-2004 Toyota Tundra, 2003 Toyota 4Runner, 2001 Toyota Prius, 1994-1997 Toyota Celica, and 1993-1997 Toyota Corolla. The Delphi AS10334 is also a fitment-focused search term for owners needing a reliable ignition knock sensor for these Toyota and Lexus platforms.

What It Helps Address

• Knock sensor fault codes related to detonation detection
• Erratic ignition timing caused by inaccurate sensor input
• Engine pinging or spark knock under load
• Check engine light concerns tied to the knock sensor circuit
• Driveability issues from degraded sensor signal quality

Installation Notes

Verify connector shape, terminal style, and vehicle application before installation. This sensor uses a round male connector with pin-style terminals and does not include mounting hardware. For best results, inspect the harness connector, clean the mounting surface, and confirm the replacement matches the original sensor configuration on your Toyota or Lexus model.

Quality Assurance

Delphi backs this sensor with OE-focused development and product validation methods. Each sensor is tested and calibrated to OE standards to support accurate readings and reduce comebacks.
