When diagnosing the Ford P0273 Code, it is important to know the causes and potential solutions that can help to resolve the issue. This code is triggered when the output of the fuel injector circuits are not within a calibrated limit. Common causes of this code include an open INJ5 circuit, an open INJ5RTN circuit, a short to ground in the INJ5 circuit, high resistance in the INJ5 or INJ5RTN circuits, a damaged fuel injector connector, a damaged fuel injector, or a damaged PCM. To help with troubleshooting, here is a table outlining the causes and possible solutions associated with the Ford P0273 Code.
Causes & Solutions for Ford P0273 Code
| Cause | Solution |
|---|---|
| INJ5 circuit open | Check the wiring for any breaks or corrosion and repair any issues. |
| INJ5RTN circuit open | Check the wiring for any breaks or corrosion and repair any issues. |
| INJ5 circuit short to ground | Check the wiring for any shorts to ground and repair any issues. |
| INJ5 circuit high resistance | Check the wiring for any high resistance and repair any issues. |
| INJ5RTN circuit high resistance | Check the wiring for any high resistance and repair any issues. |
| Damaged fuel injector connector | Replace the fuel injector connector. |
| Damaged fuel injector | Replace the fuel injector. |
| Damaged PCM | Replace the PCM. |
Dealing with the Ford P0273 Code can be a daunting task. When this code is triggered, it means that the output of the fuel injector circuits are not within a calibrated limit. Understanding the causes and potential solutions associated with this code is essential in order to identify and resolve any issues. Common causes include an open INJ5 circuit, an open INJ5RTN circuit, a short to ground in the INJ5 circuit, high resistance in the INJ5 or INJ5RTN circuits, a damaged fuel injector connector, a damaged fuel injector, or a damaged PCM. In order to effectively address these issues, it is important to know the appropriate solutions associated with each cause. This table provides an overview of the causes and the potential solutions that can help to resolve the issue.
INJ5 Circuit Open
When the INJ5 circuit is open, the output of the fuel injector circuits are not within a calibrated limit, triggering the Ford P0273 Code. The first step in troubleshooting this issue is to check the wiring for any breaks or corrosion. This can be done with a multimeter to test the resistance levels. If any breaks or corrosion is detected, they must be repaired as soon as possible to prevent further damage.
INJ5RTN Circuit Open
If the INJ5RTN circuit is open, it can also trigger the Ford P0273 Code. In this case, it is important to check the wiring for any breaks or corrosion. A multimeter can be used to test the resistance levels in order to identify any issues. If any breaks or corrosion is detected, they must be repaired as soon as possible to prevent further damage.
INJ5 Circuit Short to Ground
When the INJ5 circuit is short to ground, this can trigger the Ford P0273 Code. To troubleshoot this issue, it is necessary to check the wiring for any shorts to ground. This can be done with a multimeter to test the resistance levels. If any shorts to ground are detected, they must be repaired as soon as possible to prevent further damage.
INJ5 and INJ5RTN Circuits High Resistance
If the INJ5 and INJ5RTN circuits have high resistance, this can also trigger the Ford P0273 Code. In this case, it is important to check the wiring for any high resistance. A multimeter can be used to test the resistance levels in order to identify any issues. If any high resistance is detected, they must be repaired as soon as possible to prevent further damage.
Damaged Fuel Injector Connector
When the fuel injector connector is damaged, this can also trigger the Ford P0273 Code. To address this issue, the fuel injector connector must be replaced. This should be done as soon as possible to prevent any further damage.
Damaged Fuel Injector
If the fuel injector is damaged, this can also trigger the Ford P0273 Code. To resolve this issue, the fuel injector must be replaced. This should be done as soon as possible to prevent any further damage.
Damaged PCM
When the PCM is damaged, this can also trigger the Ford P0273 Code. To address this issue, the PCM must be replaced. This should be done as soon as possible to prevent any further damage.
Conclusion
The Ford P0273 Code is triggered when the output of the fuel injector circuits are not within a calibrated limit. Identifying the causes and potential solutions associated with this code is essential in order to troubleshoot any issues. Common causes include an open INJ5 circuit, an open INJ5RTN circuit, a short to ground in the INJ5 circuit, high resistance in the INJ5 or INJ5RTN circuits, a damaged fuel injector connector, a damaged fuel injector, or a damaged PCM. This article provides an overview of the causes and potential solutions that can help to resolve the Ford P0273 Code issue.
