Hi guys,

I have a problem. Bought a used car - European 2003 Honda Accord 2.4 140kW with automatic 5-speed transmission.

The problem is that when driving at a certain speed, the engine RPM is relatively high.

For example, drive 5gear :

62miles/h - About 2900RPM
74miles/h - About 3400RPM
93miles/g - About 4100RPM

The dashboard lights up "Check engine" with this active faults
- 00-07(P0606) ECM/PCM processor malfunction ;
- 67-01(P0420) Catalyst system efficiency below threshold.

Maybe you have had a similar problem?

Thanks a lot.

Sincerely,
OvisHPI
