P1184 2000 Ford F150 Code - Engine Oil Temperature Out Of Self Test Range
Quick Answer
The Engine Oil Temperature (EOT) sensor is a thermistor device in which resistance changes with temperature. Common causes include Engine not at operating temperature, Cooling system problem of stuck thermostat, Faulty Engine Oil Temperature (EOT) sensor. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P1184 2000 Ford F150 Description
Thermistor-type sensors are considered passive sensor. A passive sensor is connected to a voltage divider network so that varying the resistance of the passive sensor causes a variation in total current flow.
Voltage that is dropped across a fixed resistor in a series with the sensor resistor determines the voltage signal at the ECM. This voltage signal is equal to the reference voltage minus the voltage drop across the fixed resistor.
The EOT sensor measures the temperature of the engine oil. The sensor is typically threaded into the engine oil lubrication system. The ECM can use the EOT sensor input to determine the following:
- On variable cam timing (VCT) applications the EOT input is used to adjust the VCT control gains and logic for camshaft timing.
- The ECM can use the EOT sensor input in conjunction with other ECM inputs to determine oil degradation
- The ECM can use EOT sensor input to initiate a soft engine shutdown. To prevent engine damage from occurring as a result of high oil temperature, the ECM has the ability to initiate a soft engine shutdown. Whenever engine RPM exceeds a calibrated level for a certain period of time, the ECM will begin reducing power by disabling engine cylinders.
What are the Possible Causes of the DTC P1184 2000 Ford F150?
- Engine not at operating temperature.
- Cooling system problem of stuck thermostat.
- Faulty Engine Oil Temperature (EOT) sensor
- Engine Oil Temperature (EOT) sensor harness is open or shorted
- Engine Oil Temperature (EOT) sensor circuit poor electrical connection
- Faulty Engine Control Module (ECM).
How to Fix the DTC P1184 2000 Ford F150?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
What is the Cost to Diagnose the Code?

2. What are the symptoms of P1184 on a 2000 Ford F150?
Symptoms may include an illuminated check engine light, poor engine performance, or incorrect oil temperature readings.
3. What causes the P1184 code on a 2000 Ford F150?
Common causes include a faulty Engine Oil Temperature sensor, damaged wiring or connectors, or a malfunctioning Powertrain Control Module (PCM).
4. Can P1184 affect engine performance?
Yes, inaccurate oil temperature readings can lead to improper engine adjustments, potentially affecting performance and fuel efficiency.
5. How do I diagnose the P1184 code on my 2000 Ford F150?
Start by inspecting the EOT sensor, wiring, and connectors for damage or corrosion. Use a multimeter to test the sensor’s resistance and ensure proper voltage signals.
6. Can I drive with the P1184 code on my 2000 Ford F150?
Driving with this code is not recommended, as it can lead to improper engine operation or long-term damage if the oil temperature is not accurately monitored.
7. How do I fix the P1184 code on a 2000 Ford F150?
Common fixes include replacing the EOT sensor, repairing damaged wiring, cleaning corroded connectors, or updating the PCM software if necessary.
8. Where is the Engine Oil Temperature sensor located on a 2000 Ford F150?
The EOT sensor is typically located near the oil filter or in the engine block, depending on the engine configuration.
9. How much does it cost to fix the P1184 code on a 2000 Ford F150?
The cost depends on the repair needed. Replacing the EOT sensor typically costs $50–$150, while wiring repairs or PCM updates may vary.
10. Can a faulty EOT sensor cause other engine problems?
Yes, a faulty EOT sensor can lead to incorrect engine adjustments, potential overheating, or oil pressure issues over time.
