What P2241 means
P2241 reports the pump-current circuit of the bank 2 front wide-band sensor at too low a level, typically a grounded wire or a sensor that cannot pump enough oxygen. No manufacturer publicly documents P2241 with thresholds. The bank 1 twin P2238 is described by Saab for its 2.0 turbo, where the signal must climb past 1.7 V on deceleration with the injectors off; a V engine would run the same logic per bank. Ford instead files a grounded pump-current wire under P0151 and keeps P2240 for the open line. CARB demands that fuel-control sensors be checked for broken or shorted circuits and for implausible readings, with separate codes where practical. P2240 is the open circuit, P2242 the high-side fault on bank 2. Bank 2 fuelling falls back to open-loop values.
P2241 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modeNot expected
- Repair difficultyMedium, DIY possible
- Typical labor0.5 to 2.5 hours
- Clears after repairAfter a drive cycle
Symptoms of P2241
- Check engine light
- Higher fuel consumption from open-loop fuelling on bank 2
Common causes of P2241
- Most likelyBank 2 pump-current wire shorted to ground
- PossibleAged bank 2 front sensor with weak pump cell
- Less likelyFault in the ECM sensor interface for bank 2
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2241 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 2 | Area: fuel and air metering (injector circuit). |
| 41 | The exact fault in that area. |
What to do next
- Note P2241 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P2241
What does P2241 mean?
P2241 means "O2 Sensor Positive Current Control Circuit Low (Bank 2 Sensor 1)". P2241 reports the pump-current circuit of the bank 2 front wide-band sensor at too low a level, typically a grounded wire or a sensor that cannot pump enough oxygen. It is a generic code, so it means the same on every make.
Is it safe to drive with P2241?
Usually yes, for a short time, if the check engine light is steady and the car drives normally. If the light flashes or the car runs badly, stop and have it checked.
Will P2241 fail an emissions test?
Yes, it can. P2241 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P2241 to fix?
Difficulty: medium. A typical repair takes 0.5 to 2.5 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P2241 clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
