Honda Jazz engine misfire caused by faulty ECU

Honda Jazz misfiring ECU repair

Honda Jazz engine ECU malfunction will commonly cause constant engine misfire and the illumination of the EML (engine management light). Misfire faults will begin as soon as the engine has been started.

 

With the engine skipping one of the combustion cycle steps this will cause rough and jerky performance. It is very important to diagnose this issue as soon as possible to prevent the problem worsening and potentially causing damage elsewhere.

 

When diagnosing the vehicle with fault code readers you will find codes logged in the engine ECU for cylinder one, two or three misfire. Even after replacing the injectors, plugs and coil pack the fault codes and misfire will remain. This is a common indicator that the Honda Jazz misfire problems are being caused by a faulty engine ECU.

 

Honda dealerships will seek to resolve this misfire problem by purchasing an expensive replacement from manufacturer, this will also require coding to the vehicle at an extra expense.

 

Our solution is far more cost-effective: we can test and rebuild your Honda Jazz ECU within 2-3 working days for a fraction of the cost of a replacement. We will provide an unlimited mile lifetime warranty as standard, unlike the short one-year manufacturer warranty, and you won’t even need to code the ECU back to the vehicle.
