Compare Honda Civic ECU repair quotes from specialist garages

The Civic has been produced since 1972 and is one of Honda's most popular models. It has a diverse lineup, from hatchbacks and sedans to coupes, with top speeds ranging from 110 to 130 mph. In 2022, The Sunday Times Motor Awards crowned the Honda Civic Type R 'Legend Car of the Year', and it was also named 'Car of the Year' at the Top Gear Awards.

As with most Hondas, the Civic has an excellent reputation for reliability. Chipped paint and missing windscreen washer caps are the main things to look for. In recent years, modified Civics have become iconic symbols of the tuner car culture, thanks to numerous appearances in the Fast and Furious film franchise.

ECU stands for engine control unit, sometimes referred to as the engine control module (ECM). This component ensures your car's engine runs smoothly by, for example, determining the amount of fuel that goes into the cylinders. You can find out more about how it works here.

Signs of a faulty ECU include misfires, the check engine light, starting problems, and engine surges or lags. ECU testing and repairs can help you work out the cause of the problem, such as faulty wiring or a bad sensor.

ECU testing uses a diagnostic tool known as an OBD scanner, which extracts information from the car's computer and allows the technician to check fault codes.

Can an ECU be repaired? Most of the time, the answer is yes; the ECU can be reprogrammed or repaired. The same applies to water damaged ECUs, as long as the damage is minimal. Some technicians may offer mobile ECU repairs at a location that's convenient for you.
