Walker Products Oxygen Sensor P/N:250-241342

Keep your Jeep's emissions monitoring on point with the Walker Products Oxygen Sensor 250-241342, a downstream oxygen sensor that installs on the 2021-2024 Jeep Wrangler. Mounted after the catalytic converter, it reads the oxygen content in the exhaust stream and reports that signal back to the engine control module.

• Downstream placement: positioned behind the catalytic converter, where it helps the ECM gauge how well the converter is doing its job.
• Exhaust-gas sensing: measures the oxygen level in the post-catalyst exhaust and sends that reading to the engine computer.
• Direct-fit replacement: a straightforward swap for the listed Jeep Wrangler applications.

An oxygen sensor is a common wear item that can slow down or drift over time. If a failing downstream sensor is the cause, you may see an illuminated check engine light, a stored catalyst-efficiency or oxygen-sensor code, or reduced fuel economy. Because these symptoms can also come from other faults in the exhaust or fuel system, diagnose the cause before replacing. When a bad downstream sensor is confirmed, this sensor replaces the worn unit.
