Can drive — fix at your convenience.
This code means the catalyst temperature sensor on bank 2 is sending readings that fall outside the normal expected range or don't change the way they should. The usual culprits are a faulty sensor, damaged wiring, or a poor electrical connection. Repairs most often involve replacing the temperature sensor and fixing any wiring or connector issues.
$120 – $400
Varies by vehicle and root cause.
Yes, almost always. This is a sensor-related code and the car usually drives normally. The main downsides are the check engine light and not passing emissions, so get it checked when convenient rather than ignoring it indefinitely.
Most repairs are on the affordable side, typically $120 to $400. The sensor itself isn't expensive, and labor is usually modest unless wiring repairs are involved.
It's a low-severity code. It rarely affects how the car drives and doesn't pose a safety risk, but it will keep the check engine light on and prevent passing emissions, so it should still be fixed.
It means the temperature sensor's signal is within its electrical limits but doesn't behave realistically, like staying flat or reading outside expected values. That points to a lazy or failing sensor rather than a dead one.
