Honda engine control units – used, genuine and tested modules

Honda engine control units available from ECUSale are genuine, used and tested electronic modules designed for Honda vehicles. We offer engine control units selected according to the part number, Bosch or Delphi reference, vehicle model, engine version and software. Our range includes ECUs for models such as the Honda Civic, Accord, CR-V and FR-V, as well as other Honda vehicles with petrol and diesel engines.

When purchasing a Honda engine control unit, it is essential to compare the references shown on the label of the original module. The same vehicle model may use different ECU versions, so control units with a similar appearance are not always interchangeable. Selection is usually based on references such as 37820, Bosch numbers beginning with 028101..., Delphi references or the complete identification shown on the ECU housing.

Used Honda engine control unit – when should it be replaced?

The engine control unit, also known as the ECU, manages engine operation, fuel injection, ignition, boost pressure, communication with sensors and many other engine parameters. A faulty Honda ECU may cause starting problems, loss of diagnostic communication, irregular engine operation, injector faults, lack of fuel pump control or the vehicle entering limp mode.

Replacing a Honda engine control unit with a genuine used module is often a more affordable alternative to buying a new part. ECUSale offers tested Honda ECUs that are checked for basic functionality before sale. Depending on the module version, it may also be possible to prepare the control unit for installation, clone data from the original ECU or configure it for a specific vehicle.

Honda Civic, Accord, CR-V and FR-V engine control units

This category includes Honda engine control units used in popular models such as the Honda Civic 2.2 i-CTDi, Honda Accord 2.2 i-CTDi, Honda CR-V 2.2 i-CTDi, Honda CR-V 2.0 i-VTEC and Honda FR-V 2.2. Available products include Bosch and Delphi control units with part numbers shown on the label of the original module.

Examples of Honda ECU references include 0281012095, 0281012131, 0281012250, 0281012583, 0281012660, 0281013407, 0281013633 and Honda references beginning with 37820. Before purchasing, we recommend sending a photo of the original ECU label so the correct part can be selected.

Selecting a Honda engine control unit by part number

The safest way to select a Honda ECU is to compare the complete part number shown on the label of the original module. Pay attention not only to the manufacturer’s number, but also to additional letter codes, the engine version, vehicle year, transmission type and software version. If necessary, you can contact us and send a photo of the original control unit so we can help verify compatibility.

If the original Honda engine control unit is damaged but its data can still be read, cloning may be possible. This allows the used control unit to receive data from the original module and be matched more closely to the vehicle. In some cases, programming or adaptation in the vehicle may also be required.

Common symptoms of a faulty Honda engine control unit

A faulty Honda ECU may cause a range of problems. Common symptoms include difficulty starting the engine, stalling while driving, no response from the accelerator pedal, injector faults, loss of communication with diagnostic equipment, an illuminated check engine light, irregular engine operation or limp mode. Diesel vehicles may also experience problems with injection control, turbocharger operation or engine sensors.

Before replacing the ECU, check the wiring, power supplies, ground connections, fuses and connectors. ECU failure may be caused by moisture, a short circuit in the electrical system, damaged wiring or an earlier incorrect vehicle repair.

Frequently asked questions about Honda engine control units

Will a used Honda engine control unit fit my vehicle?

Compatibility should be checked primarily by comparing the part number on the label of the original ECU. The vehicle model, year of manufacture, engine version, transmission type and software version are also important. Even very similar control units may contain different internal data, so all references should be compared before purchase.

How can I find the part number of a Honda ECU?

The Honda engine control unit number is printed on a label attached to the module housing. It usually includes Honda references beginning with 37820, Bosch numbers beginning with 028101 or Delphi references. For accurate identification, it is best to send a clear photo of the entire label on the original ECU.

Does a Honda engine control unit need to be programmed after installation?

In many cases, a used Honda engine control unit may require programming, adaptation or cloning of data from the original module. This depends on the vehicle model, ECU version and immobiliser system. If the original control unit can still be read, cloning the data to the replacement module is often the best solution.

Can a Honda engine control unit be cloned?

Yes, many Honda control units support data cloning from the original ECU to a used replacement module. Cloning makes it possible to transfer the most important vehicle data so the control unit can be matched more closely to the car. Whether the service can be completed depends on the condition and version of the original ECU.

Which Honda models are supported by the control units in this category?

This category includes engine control units for various Honda models, including the Honda Civic, Honda Accord, Honda CR-V and Honda FR-V. The range covers selected petrol and diesel versions, including popular 2.2 i-CTDi and 2.0 i-VTEC engines.

What are the symptoms of a faulty Honda engine control unit?

Typical symptoms of a faulty Honda ECU include starting problems, loss of diagnostic communication, irregular engine operation, injector faults, engine stalling, limp mode, lack of fuel pump control or an illuminated check engine light. The vehicle’s electrical system should also be checked before replacing the control unit.

Is it enough to buy a control unit with the same housing?

No. The appearance of the housing is not sufficient to select the correct Honda engine control unit. The most important factors are the references on the label, the software version and the vehicle configuration. Control units with identical housings may differ internally and may not operate correctly after installation.

Does ECUSale help select the correct Honda engine control unit?

Yes. To select the correct Honda ECU, send a photo of the original module label together with information about the vehicle, including the model, year of manufacture, engine capacity, power output, transmission type and symptoms of the fault. Based on this information, we can help identify the appropriate part.
