How to service the knock sensor (KS) on Ford Freestar?

Service of the knock sensor requires disabling power from the battery ground cable first. Begin by removing the air cleaner outlet pipe followed by front and rear roll restrictor bolts to uninstall the roll restrictor for later reinstallation with 63 Nm (46 lb-ft) torque specification. You need to remove both upper and lower roll restrictor bolts together with the roll restrictor bracket before reinstalling them with 90 Nm (66 lb-ft) torque. The KS electrical connector needs to be disconnected while performing the KS nut removal. Reinstall the nut after installation then tighten it to 20 Nm (15 lb-ft). Reinstallation should be finished by reversing every step of the removal process.
