Question

When I search the code in your list for Infiniti G35X (2005) I don't see P0340 and you jump from •P0335 (Crankshaft Position Sensor Circuit) to P0420 (catalyst System Efficiency Below Threshold Bank 1). Is that an error (https://www.autocodes.com/year/2005/Infiniti/g35/3)Read more: https://www.autocodes.com/year/2005/infiniti/g35#ixzz3zJYR1776

HI there,

This is an error, P0340 is the bank 1 cam position sensor fault. This is usually a result of a bad cam sensor and once replaced the light should go out on it's own.
