Detailed Description

Walker Products 242-1030 is an emission control sensor used to detect engine knock and send a signal to the vehicle’s control system so ignition timing can be adjusted as needed. This helps maintain proper combustion control in applications such as the 1999-2004 Nissan Frontier, 2000-2004 Nissan Xterra, 1999-2002 Mercury Villager, 1999-2002 Nissan Quest, and 2000 Nissan Pathfinder. This part cross-references Standard Ignition KS6 and KS107 for the same application.

What It Helps Address

• Knock sensor fault codes
• Audible spark knock or detonation
• Rough engine operation related to timing correction
• Check engine light concerns tied to knock sensor circuit issues
• Driveability problems caused by inaccurate knock feedback

Installation Notes and Tips

Verify connector style, terminal count, and sensor length before installation. This part uses a single rectangular female connector with blade terminals and does not include a wiring harness or mounting hardware. Confirm vehicle application carefully for the 2000 Nissan Pathfinder, which is listed for models from January 2000 only. For fitment verification, match the vehicle year, make, model, and sensor location before service.
