Code P0187 2000 Ford F150 Description
The P0187 diagnostic trouble code (DTC) for a 2000 Ford F150 indicates a problem with the Engine Fuel Temperature Sensor B Circuit registering a low input. The fuel temperature sensor is a crucial component that measures the temperature of the fuel in the fuel tank. This information is vital for the engine control module (ECM) to adjust the air-fuel mixture and ignition timing for optimal performance and fuel efficiency. When the sensor detects a low input signal, it means that the fuel temperature is lower than expected, which can lead to various issues with the vehicle's operation.
Common Causes of P0187 2000 Ford F150
- Faulty fuel temperature sensor
- Wiring or connector issues in the fuel temperature sensor circuit
- Corrosion or damage to sensor wiring
- ECM software or hardware issues
- Fuel system contamination affecting sensor readings
Symptoms of P0187 2000 Ford F150
- Decreased fuel efficiency
- Rough idling or engine misfires
- Hesitation or lack of power during acceleration
- Check Engine Light illuminated
- Potential engine stalling
How to Fix P0187 2000 Ford F150
- Use an OBD-II scanner to confirm the P0187 code and verify the fuel temperature sensor's low input signal.
- Inspect the wiring and connectors associated with the fuel temperature sensor for any damage or corrosion. Repair or replace as needed.
- Test the fuel temperature sensor using a multimeter to ensure it is functioning correctly. Replace the sensor if it is faulty.
- Clear the DTC and reset the ECM to see if the code returns. Test drive the vehicle to verify that the issue has been resolved.
- If the problem persists, further diagnostics may be necessary to identify any underlying issues with the fuel system or ECM.
Cost to Fix P0187 2000 Ford F150
The typical repair costs for addressing a P0187 code on a 2000 Ford F150 can vary depending on the specific cause of the issue. In general, replacing a faulty fuel temperature sensor can cost between $50 and $150 for the part, with additional labor costs ranging from $80 to $150 per hour. The total repair cost can range from $150 to $300 or more, depending on the extent of the repairs needed. It's important to note that diagnosis time and labor rates can vary based on location, vehicle make and model, and the specific repair shop. It's advisable to check with local auto repair shops for a more accurate estimate based on your individual circumstances.
Tech Notes for P0187 2000 Ford F150
The comprehensive component monitor (CCM) monitors the EFT sensor circuit to the PCM for low voltage. If voltage were to fall below a calibrated limit and amount of time during testing, the test will fail.

Frequently Asked Questions about P0187 2000 Ford F150 Code
1. What does the OBDII code P0187 indicate on a 2000 Ford F150?
The code P0187 indicates that the Engine Fuel Temperature Sensor B has detected a low input, suggesting that the voltage or resistance input from the sensor is below the expected range set by the manufacturer.
2. What are common symptoms of the P0187 code in a 2000 Ford F150?
Common symptoms include a check engine light, decreased fuel efficiency, possible stalling or difficulty starting the engine, and potentially a noticeable drop in engine performance.
3. What can cause the P0187 code to appear in a 2000 Ford F150?
Possible causes include faulty or damaged fuel temperature sensor, poor electrical connections at the fuel temperature sensor, or a short in the wiring harness connected to the sensor.
4. How do you diagnose the P0187 code in a 2000 Ford F150?
Diagnosis typically involves using an OBD-II scanner to verify the code, visually inspecting the wiring and connectors, and testing the fuel temperature sensor with a multimeter to check for proper voltage and resistance.
5. What repairs can fix the P0187 code in a 2000 Ford F150?
Repairs might include replacing the faulty fuel temperature sensor, repairing or replacing damaged wiring or connectors, or addressing any other electrical issues found during the diagnostic process.
6. Is it safe to drive a 2000 Ford F150 with the P0187 code?
While it may be safe to drive for short distances, it's advisable to address the issue promptly as it can affect the fuel efficiency and overall performance of the engine, potentially leading to further complications.
7. How urgent is it to address the P0187 code in a 2000 Ford F150?
It is moderately urgent to address this code. Delaying repairs can lead to reduced engine performance and increased fuel consumption, which may cause additional strain on the engine components over time.
8. Does the P0187 code affect the fuel economy of a 2000 Ford F150?
Yes, this code can affect fuel economy. The engine control module may not be able to accurately calculate the correct fuel-to-air ratio if it's receiving incorrect data from the fuel temperature sensor, leading to inefficient fuel usage.
