TSB's

Honda: Along came a spider...

This TSB applies to all 2006-2011 Honda Civics (except Si and GX). The MIL is on with DTC P2422 stored (EVAP canister vent shut valve stuck closed malfunction). The likely cause is spider webs that are clogging the EVAP canister vent tube. The corrective action involves replacing the EVAP canister vent tube. 2007-2011 models require canister drain tube P/N 17744-SNA-A01. 2006 models require P/N 17744-SNA-A10.

Raise the vehicle on a lift and remove the EVAP canister cover. Locate both ends of the EVAP canister vent tube. Detach the vent tube mounting clips and disconnect the vent tube from the EVAP canister and the fitting on the body.

Remove the left front fuel tank support strap bolt and loosen the strap’s rear bolt. Remove the original EVAP canister vent tube and install the new replacement vent tube. Reinstall the left front fuel tank support strap bolt and torque both strap bolts to a value of 28 lb-ft.

Connect the vent tube to the EVAP canister and the fitting on the body. Secure the vent tube with the mounting clips. Reinstall the EVAP canister cover.

Clear the DTCs with the HDS (or similar tool) and run the EVAP system function test.
