2004 Nissan Altima P0045 Fault Code Meaning and Diagnosis

Model: 2004 Nissan Altima Fault Code: P0045 Posted: 2008-07-26 20:13

I'm experiencing a P0045 diagnostic trouble code on my 2004 Nissan Altima, and I can't find clear information about what this code means. The code is related to the fuel pump control circuit, specifically indicating a problem with the fuel pump control valve or its associated wiring. This issue may result in poor engine performance, difficulty starting, or stalling. Can anyone confirm the exact cause of P0045 on a 2004 Nissan Altima and suggest troubleshooting steps? Thanks for any insights!
