Nissan Versa 2007 P1701 and P0420 Diagnostic Help: What Causes and How to Fix?

Model: Nissan Versa Fault Code: P0420 Posted: 2015-07-29 23:09

Hi everyone, I own a 2007 Nissan Versa and recently received diagnostic trouble codes P1701 and P0420. A technician at Advanced Auto Parts explained that P1701 relates to the transmission system, while P0420 is associated with the oxygen sensor in the exhaust system. However, they couldn't provide specific guidance on how to resolve these issues. I'm looking for clear advice: What are the likely causes of these codes? Can I fix them myself at home, or do I need to visit a professional shop or dealership? Are genuine parts required? And is the repair cost typically high? Any insights or troubleshooting steps would be greatly appreciated. Thanks in advance! Best regards, brp

If your car runs smoothly and there are no performance issues, try resetting the codes first. If they return after a reset, it's recommended to have a professional perform a full diagnostic scan to identify root causes.

Thanks for the quick reply! Yes, my car is running fine as before. I'm wondering if disconnecting the battery cables for 15 minutes and then reconnecting will properly reset the codes? Is that a reliable method?

Yes, disconnecting the battery for 15 minutes is a common and effective way to clear stored diagnostic codes. It resets the ECU memory without requiring tools or professional equipment.

After resetting, the codes returned. I took it to a Nissan dealership, where they diagnosed P0420 and provided a repair quote of $1,260 — $960 for parts and $300 for labor. The parts include: - Part Number 20010-EM31A SPORD TUBE-EXH F: $747.47 (with $160 core deposit) - Part Number 20695-ED10E 105D BEARING SE: $28.45 - Part Number 20695-8H310 103A BEARING SE: $23.91 The cost seems high, especially for a P0420 fix. Are there more affordable alternatives? I'm looking to reduce expenses without compromising reliability.

For a budget-friendly approach to P0420 on the Nissan Versa 2007, consider applying anti-fouler treatment to the post-catalyst oxygen sensor. This can help restore sensor performance and may resolve the code without replacing expensive components.
