The automobile fault code P1184 indicates a problem with the engine’s oil temperature. The most common symptom is the engine light being illuminated or the service engine soon warning light appearing. The cause of this fault code can be attributed to various factors, such as the engine not being at operating temperature, a stuck thermostat in the cooling system, a faulty engine oil temperature (EOT) sensor, an open or shorted EOT sensor harness, poor electrical connection in the EOT sensor circuit, or a faulty engine control module (ECM).

To fix this issue, it is recommended to visually inspect the wiring harness and connectors, checking for any damage or corrosion.

Additionally, look for any broken, bent, pushed out, or corroded pins in the connectors.

The repair time for this issue is estimated to be around 1.0 hour.

Repair Importance Level10.0 (Out of 10)
Estimated Repair TimeApproximately 1.0 hour
Repair Difficulty Level6.67 (Out of 10)

When the engine light is on or the service engine soon warning light is illuminated, it could be a sign of the p1184 fault code.

  • The symptoms of the automobile fault code P1184 include the Engine Light being ON or the Service Engine Soon Warning Light being illuminated.

The automobile fault code P1184 can be caused by various factors, including engine temperature, cooling system issues, sensor malfunctions, and problems with the engine control module.

  • The fault code P1184 can be caused by the following: engine not at operating temperature, stuck thermostat in the cooling system, faulty Engine Oil Temperature (EOT) sensor, open or shorted EOT sensor harness, poor electrical connection in the EOT sensor circuit, and a faulty Engine Control Module (ECM).

To fix fault code p1184, start by visually inspecting the wiring harness, connectors, and components for any damage or corrosion.

  • To fix the automobile fault code P1184, start by checking the possible causes mentioned above.
  • Then, visually inspect the wiring harness and connectors related to the issue.
  • Look for any damaged components and check if there are any broken, bent, pushed out, or corroded pins in the connectors.
  • This fix is estimated to take approximately 1.0 hour.

The factors influencing the diagnosis and fixing cost of the automobile fault code P1184 are the estimated repair time and the hourly rate charged by auto repair shops.

The estimated repair time for this fault code is 1.0 hour. Auto repair shops typically charge between $75 and $150 per hour for their services.

These factors will determine the overall cost of diagnosing and fixing the P1184 fault code.

The P1184 fault code indicates that the engine oil temperature is outside of the self-test range. This code is triggered when the Engine Control Module (ECM) detects that the temperature measured by the Engine Oil Temperature (EOT) sensor is not within the expected range during the self-test. The EOT sensor is a thermistor device that measures the temperature of the engine oil. It works by changing its resistance based on the temperature.

The varying resistance affects the voltage drop across the sensor terminals, which provides an electrical signal to the ECM. The ECM uses the EOT sensor input for various purposes.

On variable cam timing (VCT) applications, it adjusts the VCT control gains and logic for camshaft timing. It also uses the EOT sensor input, along with other inputs, to determine oil degradation.

Additionally, the ECM can initiate a soft engine shutdown if the oil temperature becomes too high to prevent engine damage. When the P1184 code is triggered, it means that the engine oil temperature is not within the expected range during the self-test. This could indicate a problem with the EOT sensor or the engine oil temperature itself.

It is important to diagnose and fix this issue to ensure proper engine performance and prevent potential damage.

What are the possible causes of fault code P1184 in an automobile?

If you’re seeing the fault code P1184 in your automobile, it’s important to address it promptly. This code is often accompanied by the engine light being on or the service engine soon warning light. The possible causes for this fault code include the engine not being at operating temperature, a cooling system problem with a stuck thermostat, a faulty Engine Oil Temperature (EOT) sensor, an open or shorted EOT sensor harness, a poor electrical connection in the EOT sensor circuit, or a faulty Engine Control Module (ECM). To fix this issue, start by visually inspecting the wiring harness and connectors, checking for any damage or corrosion. Additionally, look out for broken, bent, pushed out, or corroded connector pins.

How can I determine if the engine is not at operating temperature when the P1184 fault code is triggered?

If you see the Engine Light ON or the Service Engine Soon Warning Light, it could be due to the engine not being at operating temperature. This can be caused by a cooling system problem with a stuck thermostat, a faulty Engine Oil Temperature (EOT) sensor, an open or shorted EOT sensor harness, a poor electrical connection in the EOT sensor circuit, or a faulty Engine Control Module (ECM). To determine if the engine is not at operating temperature when the P1184 fault code is triggered, visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.

What steps should I take to visually inspect the wiring harness and connectors when troubleshooting fault code P1184?

To visually inspect the wiring harness and connectors when troubleshooting fault code P1184, start by checking the “Possible Causes” listed above. Then, visually inspect the related wiring harness and connectors. Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins. This thorough inspection will help identify any issues with the engine oil temperature sensor or the engine control module, allowing for a proper fix to be implemented.

p1184 error fault code explained

If your engine light is on and you’re experiencing issues with your engine temperature, it could be due to a few different causes. First, check if your engine is not at operating temperature.

If that’s not the issue, it could be a problem with a stuck thermostat in your cooling system or a faulty Engine Oil Temperature (EOT) sensor. Additionally, check the wiring harness and connectors for any damage or poor electrical connections.

Lastly, it’s possible that the Engine Control Module (ECM) is faulty.

Take a look at these possible causes and visually inspect the related components to find the solution.
