2008 Nissan Rogue with P0021 and P0022 OBD2 Diagnostic Codes Explained

Model: nissan rogue Fault Code: P0021 Posted: 2016-01-02 10:15

I recently discovered my 2008 Nissan Rogue has two diagnostic trouble codes: P0021 and P0022. These codes are related to the intake valve position sensors in Bank 1 and Bank 2, respectively. The check engine light came on shortly after a routine inspection. While I believe this issue might be fixable at home, I'm unsure whether to replace both valves or just one. Since P0021 refers to Bank 1 and P0022 to Bank 2, I'm wondering which cylinder bank requires replacement — or if it's better to have a professional diagnose the problem. Any guidance on this would be greatly appreciated.

I've just noticed my wife's check engine light came on a day after her vehicle was inspected. I used an OBD2 code reader and found P0021 and P0025 codes. The issue appears straightforward, but I'm confused about which bank to replace — Bank A (Bank 1) or Bank B (Bank 2)? Is this something I can handle myself, or should I take it to a professional shop for diagnosis?
