CAPS Pump Codes 268 and 456 Info

Codes 268 and 456 are for the accumulator pressure sensor. Our experience has been that if other codes are present the replacement of the pressure sensor will not cure the problem. If either or both 268 and 456 are the only code present replacement of the pressure is rarely the cure. Far more often the problem is a restriction or air leak between the tank and the injection pump inlet. I have included the ISC manual diagnostic procedures for both air and restriction with the pages for codes 268 and 456.

A weak gear pump or worn accumulator will also trigger either or both of these codes even though they are not mentioned in the diagnostic procedure.
