If you own a Ford and the check engine light has come on with the P1184 code, you may be wondering what this code means and what you can do about it. P1184 stands for Engine Oil Temperature Sensor Out of Self-Test Range, which is a technical way of saying the engine oil temperature (EOT) sensor has detected an abnormal reading. This code has several potential causes, ranging from a damaged EOT sensor to a damaged harness or harness connector. Understanding this code’s causes and potential solutions is essential for getting your Ford back on the road. Ford P1184 Code can be tricky to solve, but with the proper knowledge, it can be done.

Causes and Solutions of Ford P1184 Code
| Cause | Solution |
|---|---|
| EOT circuit open | Check for broken wires in the EOT circuit |
| EOT circuit short to ground | Check for damaged insulation on the circuit wires |
| EOT circuit short to voltage | Check for damaged or corroded connectors in the EOT circuit |
| Damaged EOT sensor | Replace the EOT sensor if it is found to be defective |
| Damaged harness/connector | Replace the damaged harness or connector |
EOT Circuit Open
When the Ford P1184 code appears, it is usually because of an issue with the EOT circuit. The EOT circuit is responsible for monitoring the temperature of the engine oil. If the circuit is open, it means that there is a break in the circuit, resulting in an abnormal reading. To fix this issue, you will need to check for any broken wires in the EOT circuit.

EOT Circuit Short to Ground
Another potential cause for the Ford P1184 code is a short-to-ground in the EOT circuit. If this is the case, it means that the circuit is being grounded through something other than the EOT sensor. To fix this issue, you will need to check the insulation on the circuit wires, as this can often be damaged.
EOT Circuit Short to Voltage
A transient voltage in the EOT circuit can also cause the Ford P1184 code. This means the circuit is powered by a voltage other than the EOT sensor. To fix this issue, you will need to check for any damaged or corroded connectors in the EOT circuit.

Damaged EOT Sensor
In some cases, the cause of the Ford P1184 code is a damaged EOT sensor. If this is the case, you will need to replace the EOT sensor. This is usually a relatively straightforward task, but it is essential to make sure that the EOT sensor is compatible with your Ford model.
Damaged Harness/Connector
Finally, the Ford P1184 code can be caused by a damaged harness or connector. If this is the case, you will need to replace the damaged harness or connector. This is usually a straightforward task, but it is essential to make sure that the harness or connector is compatible with your Ford model.
