Detailed Description

The Spectra S10451 is an engine camshaft position sensor used to report camshaft position to the vehicle’s engine management system. That signal helps the ECU determine which cylinder is firing, allowing proper coordination of ignition timing and fuel delivery. This part is used on select Lexus GS430, LS430, SC430, and Toyota Land Cruiser, Tundra, 4Runner, Sequoia, GX470, and LX470 applications. This part cross-references Standard Ignition PC409 for the same application.

What It Helps Resolve

• Check engine light related to camshaft position sensor faults
• Hard starting or extended crank conditions
• Rough idle caused by incorrect timing input
• Misfire concerns tied to camshaft signal loss
• Fuel injection or ignition sequencing errors
