How to Check a Civic for VTEC E

The VTEC-E is the single overhead-cam version of the Honda Civic VTEC engine, designed to increase fuel economy at low rpm. Only one of the two intake valves opens a very small amount at low rpm, increasing the fuel/air atomization in the cylinder, utilizing a leaner mixture. It is necessary for the technician to know if the Civic is equipped with a VTEC or a VTEC-E model engine when attempting to diagnose a problem. Identifying a VTEC-E requires little more than raising the hood and making a phone call.

Instructions

1

Pull the inside hood release, and lift the hood of the Honda Civic.

2

Find the engine model number engraving located toward the front of the engine just below the head gasket. Remove any grease or dirt that covers the engraving.

3

Read and record the engraving.

4

Contact the service department at a Honda dealer and ask a service representative to decode the engraved number to determine if the engine is a VETEC-E.
