2009 Infiniti G37 ProblemsCheck Engine Light With Code P0603
A weak battery may result in illumination of the Check Engine Light with fault code P0603 stored.
The Check Engine Light may illuminate due to an EVAP system charcoal canister purge control valve fault. Our technicians tell us that if the valve requires replacement, a revised part is available which should be installed.
Vehicles with a 7 speed automatic transmission may experience a harsh downshift from 4th to 3rd gear on deceleration. Our technicians tell us revised control module software is available to correct this concern. On higher mileage vehicles other faults may cause transmission shifting issues. Whenever a transmission repair is performed, the control module should be checked for the latest software and updated if necessary.
