Ford code P2243 is a trouble code that is triggered when a problem is detected with the circuit used to determine the oxygen content in the exhaust gas. The code P2243 is a common issue among Ford vehicles and is a result of a malfunctioning universal heated oxygen sensor bank 1, sensor 1 (HO2S11) or an open UO2S11 circuit. This article will explore the possible causes of this error code and solutions to fix it. To understand the issue better, we have created a table below outlining the causes and solutions of this issue.
Causes and Solutions of Ford Code P2243
| Causes | Solutions |
| ————- | ————- |
| UO2S11 circuit open | Check wires, connectors and fuses for any issues |
| Damaged universal heated oxygen sensor bank 1, sensor 1 (HO2S11) | Replace the HO2S11 sensor || Wiring or connector issues | Check for loose or corroded connectors |
Open UO2S11 Circuit
Ford code P2243 can be caused by an open UO2S11 circuit. This issue can be caused by a few different issues, such as loose or corroded connectors, damaged wires, or a defective fuse. In order to fix this issue, it is important to inspect all the wires, connectors, and fuses to determine the source of the issue. If the issue is caused by faulty wiring or connectors, then they will need to be replaced.
Damaged Universal Heated Oxygen Sensor Bank 1, Sensor 1 (HO2S11)
Another possible cause of Ford code P2243 is a damaged universal heated oxygen sensor bank 1, sensor 1 (HO2S11). This sensor is responsible for determining the oxygen content in the exhaust gas and is a common issue among Ford vehicles. If the HO2S11 sensor is damaged, then it will need to be replaced in order to resolve the issue.
Conclusion
Ford code P2243 is a common issue among Ford vehicles and is a result of a malfunctioning universal heated oxygen sensor bank 1, sensor 1 (HO2S11) or an open UO2S11 circuit. This article discussed the possible causes of this Ford Code P2243 and solutions to fix it. It is important to inspect all the wires, connectors, and fuses to determine the source of the issue, and if the HO2S11 sensor is damaged, then it will need to be replaced in order to resolve the issue.
