the best way is identify the fault is read the error code using a OBD scanner.

Without giving a code you're not going to get the right answer...

P2640 isn't listed under the trouble codes that I have. It goes from P2631 to P2646.

Check your oil level. You may be getting a VTEC code due to lack of oil pressure at the VTEC pressure switch.

Maybe your scan tool is messed up? It should read Pxxxx. P2642 isn't listed either. What are you using to pull the code?
