Standard Ignition PT2 Ignition Knock (Detonation) Sensor Harness

Standard Ignition PT2 Knock Sensor Harness

Standard Ignition PT2 is an ignition knock sensor harness built for direct replacement on select Toyota and Lexus applications. It uses a straight, push-on design with three female connectors and 18-gauge wiring to support a clean electrical connection in the engine management circuit.

Key Features

• Direct-mount ignition knock (detonation) sensor harness
• Straight layout with push-on attachment method
• Three square female connectors with brass blade terminals
• Gray plastic construction with 12-volt electrical specification
• 18-gauge wiring harness, 19.25 inches long
• Compatible with select Toyota Camry, Avalon, Highlander, Sienna, Solara, and Lexus ES300 and RX300 applications

Application Details

PT2 is used in knock sensor wiring circuits where a secure, direct connection is needed between the sensor and the vehicle harness. This Standard Ignition PT2 harness is listed for 1995-2006 Toyota Camry, 1996-2005 Toyota Avalon, 2001-2003 Toyota Highlander, 1998-2003 Toyota Sienna, 1999-2002 Toyota Solara, 1996-2001 Lexus ES300, and 1999-2002 Lexus RX300. It also lists a 2002-2006 Toyota Camry application manufactured in the United States for ABS wheel speed sensor use. This part cross-references Beck/Arnley 158-1794 for the same application.

What It Helps Address

• Broken or brittle knock sensor wiring
• Intermittent sensor signal loss
• Corroded or loose connector terminals
• Engine performance issues tied to detonation sensor circuit faults
• Harness damage from heat, vibration, or age

Installation Notes

Verify connector shape, terminal count, and harness length before installation. PT2 uses female blade-style terminals and a direct mounting style, so the existing routing and connector orientation should be checked against the original part. Confirm vehicle-specific fitment for your Toyota Camry, Avalon, Highlander, Sienna, Solara, ES300, or RX300 before replacement.

Quality Assurance

Standard Ignition supplies this harness as a replacement electrical component for select OE-style applications. The PT2 is built with brass contact terminals and molded plastic housing for consistent connector fit and signal transfer.
