NewYall Knock Sensor Kit for Toyota & Lexus – 2-Pack with Pigtail Connector, OE Fit

NewYall 2 Knock Detonation Sensors with connector wire harness pigtail are replacement sensors engineered to fit specified Toyota and Lexus engines, restoring knock detection and ignition timing input to the engine control unit.

These two knock sensors and the included pigtail connector are designed as direct-fit replacements for a range of Toyota and Lexus models from the mid-1990s through the mid-2000s. They provide the electrical and mechanical connection the engine control module needs to monitor detonation (engine knock) so the ECU can adjust timing accordingly. Each sensor is assembled to match OE mounting and wiring styles for a straightforward swap.

Which vehicles will accept these NewYall knock sensors?

The kit covers many Toyota and Lexus models across multiple years, including sedans, coupes and SUVs. Confirm the part's compatibility with your vehicle's year and engine code before ordering to ensure the correct fit and mounting orientation.

• Toyota: Avalon (2000–2004), Camry (1999–2006), Celica (2000–2002)
• Toyota continued: Highlander (2001–2004), Sienna (2000–2003), Solara (1999–2003)
• Lexus: ES300 (2000–2003), GS300 (2005), IS300 (2001–2005)
• Lexus continued: SC300 (1994–2000), RX300 (2000–2003), RX330 (2004–2006)

How do these sensors install and what should I expect during replacement?

Installation typically involves disconnecting the battery, accessing the sensor locations on the engine block or head, removing the old sensors and installing the replacements with the supplied pigtail. The sensors mount to threaded bosses and use the connector harness for a secure electrical link; torque to manufacturer specs and verify routing to prevent heat or abrasion damage.

• Includes two sensors and a pre-wired connector pigtail for plug-and-play replacement.
• No cutting or splicing required when matched to the correct OEM connector type.
• Use proper torque values and a clean mounting surface to ensure accurate readings.
• Typical install time: 30–90 minutes depending on access and vehicle layout.

What symptoms indicate a failing knock sensor kit?

Failing knock sensors can trigger check-engine lights, produce timing-related performance changes, or lead the ECU to retard ignition timing as a protective measure. You may notice reduced power, lower fuel efficiency, or stored diagnostic trouble codes related to knock detection or sensor circuit faults.

• Check Engine Light with P0325/P0330 or similar knock sensor codes.
• Engine timing retard, reduced throttle response, or decreased fuel economy.
• Intermittent or inconsistent engine ping detection reported by diagnostic scans.
• Replacing both sensors and using a new pigtail often resolves electrical or grounding issues.

Are these aftermarket sensors reliable for daily driving?

NewYall sensors are produced for direct-fit replacement and are intended to meet the functional requirements of the original equipment. While aftermarket components vary, proper installation and correct vehicle match are key to dependable operation; inspect connectors and wiring for damage and secure routing away from extreme heat sources.

• Designed to match OE mounting and electrical interface for consistent signal output.
• Sold as a pair with pigtail to replace both cylinder bank sensors when applicable.
• Recommended to replace both sensors if one has failed or when restoring an older vehicle.
• Check compatibility against your VIN or factory service manual for best results.

Who is this kit for? If you own one of the listed Toyota or Lexus models and are experiencing knock-sensor-related trouble codes, timing issues, or want to proactively replace aging sensors, this NewYall two-sensor kit with pigtail is suited for DIY mechanics and professional technicians alike. It is intended for those who need a like-for-like replacement that restores the knock detection circuit and electrical connection to the engine control unit. Always verify fitment for your model year and engine before purchase and follow safe installation practices.
