Fitment note: 1.8L SOHC, automatic transmission, US market. Module sits behind the battery tray.

Check emissions and transmission type before ordering

Honda modules differ between Federal and California emissions vehicles, and between automatic and manual transmissions. Read the part number from the sticker on your existing module, or give us your VIN and we will identify the correct unit for you.

Why Honda modules must be programmed

These vehicles use an immobiliser. A replacement engine computer has to be matched to your VIN and keys before the engine will start, which is why an unprogrammed unit bought elsewhere often leaves the car cranking without firing. We handle that before the module ships, so you do not need a dealer or a locksmith.

What you receive

• Programmed to your VIN before dispatch, so it installs plug and play
• Bench-tested by our technicians before it leaves us
• Lifetime warranty for as long as you own the vehicle
• Free US shipping, typically delivered in 2-4 business days
• No core charge – keep your old unit, and no core deposit to reclaim

Common symptoms of a failed Honda Civic ECM

• Check engine light returns immediately after being cleared
• Engine shutting off for no apparent reason
• Loss of spark or no injector pulse
• Intermittent starting problems
• No communication between the scan tool and the module
