Err.2 effectively means the PGM-IV is detecting excessive resistance to the RC Valve operation, caused by either carbon build-up on the valve flaps themselves, or corrosion/dirt build-up inside the actuator cables.



It doesn't necessarily mean you need new RC Valve flaps or even new cables. You can extract the valves (the best way is with the genuine Honda tool, which you can buy from either Honda or TYGA Performance [TYTO-0014]) and clean them with a wire brush, and lubricate the cables to ensure they are free running. New cables are available from T2 Racing in Japan.

Ensure you replace the special E-clips and oil seals when you replace the RC Valve flaps.
