Detailed Description

Standard Ignition KS533 is built for vehicles that rely on a knock sensor to monitor engine vibration and help the control system respond to detonation events. The sensor uses a plug-in connector with female housing and male blade terminals, and its bolt-mount design supports secure placement on the engine. This part number is listed for 2021-2025 Ford F-150, 2022-2025 Ford Expedition, 2022-2023 Lincoln Navigator, and 2025 Lincoln Navigator applications. For buyers searching for a Ford F-150 knock sensor or Lincoln Navigator detonation sensor, KS533 provides a direct-fit service part reference.

This part cross-references DKS278 and EKS181 for the same application.

What It Helps Address

• Knock sensor fault codes related to detonation monitoring
• Engine pinging or spark knock concerns
• Unstable ignition timing response from a failed sensor signal
• Check engine light conditions tied to knock sensor circuit issues
• Driveability problems caused by inaccurate engine vibration feedback

Installation Notes and Tips

Verify connector style, terminal count, and mounting type before installation. KS533 uses a bolt-mount design with a single plug-in connector and 8-terminal interface, so the harness and mounting point must match the original configuration. Confirm vehicle coverage by year and model before ordering, especially for 2021-2025 Ford F-150, 2022-2025 Ford Expedition, and 2022-2025 Lincoln Navigator applications.

Quality Assurance

Standard Ignition supplies replacement electrical and emission control components for service applications. KS533 is built with metal and plastic materials and is listed with OE-style interchange references for application matching.
