Is it necessary to replace the sensor if there's an oxygen sensor 2 circuit fault?

For the 2011 Suzuki Liana, if you're getting a catalytic converter fault warning, there are a few things you can consider. First, you might want to confirm the diagnosis with another mechanic to ensure it's indeed the catalytic converter that's the issue. Sometimes, other components like oxygen sensors can also trigger similar warnings. If replacing the catalytic converter is necessary and the cost quoted is over two thousand, you might want to compare prices from different repair shops or consider aftermarket parts, which can sometimes be more affordable.

Changan Alsvin, ABS and anti-skid faults, diagnostic shows left front wheel speed sensor fault. I replaced it, but the lights are still on. The diagnostic still shows left front wheel speed sensor fault, but all the data streams are there. The fault can be cleared, but it comes back while driving. What should I do?
