Code result
P2241
O2 Sensor Pumping Current Circuit Low
High severity
What it means
The pumping-current line of the wide-band oxygen sensor on bank 2, sensor 1 is below the lower threshold. Wide-band sensors use a small pumping current to keep their measuring cell at lambda 1; a low value usually means an open or shorted pump cell.
Is it safe to drive?
No — stop driving
This code points to a problem that can cause damage or affect safety. Avoid driving and have the vehicle diagnosed promptly.
Most likely causes
Pump cell open or sensor failed
highOne of the most commonly reported causes for this code — check this first.
Pumping current line shorted to ground
mediumA plausible cause — test and verify before replacing parts.
Connector pins corroded - high contact resistance
lowLess common, but worth ruling out after the more likely causes.
