I have an Isuzu 2001 Rodeo with the 2.2 ,4cyl. engine. I bought a Cen-Tech code reader from harbor freight. Hooked it up and it found seven codes. The first code : PO342 ,says Camshaft position Sensor A - Bank 1 Circuit low input. second code PO401 EGR flow insufficient . Third code : PO442 EVAP Emission control system leak (small). 4th code :PO456 , Evap Emission control system leak very small . 5th code: EGR flow insuficient. 6th code: PO442 Evap emission control system leak (small). and the 7th code: PO 456 EVAP emission control leak very small. Can anyone tell me which codes are the real culprit.It gave me 4 error codes and 3 pending a total of 7. Any help would be appreciated.
Thanks
