Toyota Code P2241 is a code used to diagnose oxygen (A/F) sensor pumping current circuit low (Bank 2 Sensor 1) issues in Toyota vehicles. This code is triggered when the A1A+/A2A+ voltage is 0.5 V or lower, or when the (A1A+/A2A+) – (A1A-/A2A-) is 0.1 V or lower, or when the A/F sensor admittance is below 0.022 1/Ω. These conditions can be caused by an open or short in the A/F sensor (for Bank 1, 2 Sensor 1) circuit, the A/F sensor (for Bank 1, 2 Sensor 1) itself, or the ECM. To ensure that the Toyota Code P2241 is properly diagnosed and fixed, it is important to understand the root cause of the issue and the potential solutions to fix it.

Causes and Solutions for Toyota Code P2241
| Cause | Solution |
|---|---|
| Open or Short in A/F Sensor (for Bank 1, 2 Sensor 1) Circuit | Check the wiring and connectors for any signs of a short or open circuit. |
| A/F Sensor (for Bank 1, 2 Sensor 1) | Replace the A/F Sensor (for Bank 1, 2 Sensor 1) if it is faulty. |
| ECM | Replace the ECM if it is faulty. |
| Voltage Issues | Check the voltage for any signs of problems. |
Open or Short in A/F Sensor Circuit
If the Toyota Code P2241 is caused by an open or short in the A/F sensor (for Bank 1, 2 Sensor 1) circuit, it is important to check the wiring and connectors for any signs of a short or open circuit. This can be done using a multimeter to check the circuit’s voltage. If any signs of a short or open course are found, they should be repaired as soon as possible.
A/F Sensor
If the Toyota Code P2241 is triggered by an A/F sensor (for Bank 1, 2 Sensor 1), then the A/F sensor should be replaced. This is a relatively simple process and can be done by an experienced mechanic. It is important to ensure that the new A/F sensor is installed correctly and that all connections are secure.

ECM
If an ECM fault causes the Toyota Code P2241, the ECM should be replaced. This is a more complicated process and should only be done by an experienced mechanic. It is important to ensure that the new ECM is installed correctly and that all connections are secure.
Voltage Issues
If voltage issues cause the Toyota Code P2241, then it is important to check the voltage for any signs of problems. This can be done using a multimeter to check the circuit’s voltage. If any signs of an issue are found, they should be corrected as soon as possible.
