Frequently Asked Questions

Why does the P0420 code keep coming back after being cleared?

P0420 is a monitored code — the ECU runs the catalyst efficiency test on every cold-start cycle and sets the code when catalyst efficiency falls below the threshold. Clearing the code only resets the test; it doesn't fix the underlying cause. GarageNation's P0420 diagnosis determines whether it's a ₹3,500 O2 sensor or a ₹25,000+ catalyst replacement.

Can I pass PUC with P0420?

PUC testing in India measures tailpipe emissions (CO, HC) rather than reading OBD codes. A mildly degraded catalyst may still pass PUC but set P0420. However, if the catalyst is significantly degraded, both the P0420 code and PUC failure occur together. GarageNation resolves P0420 to ensure long-term emission compliance.
