Bosch 17212 oxygen sensor for the 2011-2012 Ram 2500 6-cylinder 6.7L and other vehicles measures the air-fuel ratio in the exhaust and reports it to the ECU. The ECU uses that signal to control the air-fuel ratio.
- Wide-band sensing gives continuous air-fuel ratio readings across the full lambda range
- Reaches operating temperature in <7 seconds for quick closed-loop control
- Withstands exhaust streams up to 1,880°F
- Metal housing, integrated heater element and TSP coating resist vibration, corrosion and contamination
Quick facts
- Part: Bosch 17212 oxygen sensor

A check engine light, rough running or poor fuel economy can mean an oxygen sensor is failing, but wiring faults or other parts can cause them too. If a failed sensor is the cause, this one replaces it. With the engine off and cool, look over the wiring and connector for cracked or melted insulation before you replace the sensor, and leave live-signal tests to a shop.
