Code P0187 1999 Ford F150 Description
The P0187 diagnostic trouble code (DTC) for a 1999 Ford F150 indicates a problem with the Engine Fuel Temperature Sensor B Circuit, specifically a low input signal. The Engine Fuel Temperature Sensor is responsible for measuring the temperature of the fuel in the fuel tank and providing this information to the engine control module (ECM). This data is crucial for the ECM to adjust the air-fuel mixture and ignition timing for optimal engine performance and fuel efficiency.
Common Causes of P0187 1999 Ford F150
- Faulty engine fuel temperature sensor
- Damaged wiring or connectors in the sensor circuit
- Malfunctioning engine control module (ECM)
- Corrosion or poor connections in the sensor circuit
- Issues with the fuel temperature sensor circuit
Symptoms of P0187 1999 Ford F150
- Decreased fuel efficiency
- Rough idling or engine misfires
- Hesitation or lack of power during acceleration
- Engine stalling or difficulty starting
- Illumination of the check engine light
How to Fix P0187 1999 Ford F150
- Begin by diagnosing the issue using a scan tool to retrieve the specific trouble code and data related to the engine fuel temperature sensor.
- Inspect the wiring and connectors in the sensor circuit for any damage, corrosion, or poor connections. Repair or replace as needed.
- Test the engine fuel temperature sensor using a multimeter to ensure it is functioning correctly. Replace the sensor if it is faulty.
- Clear the trouble code from the ECM's memory using the scan tool and perform a test drive to verify that the issue has been resolved.
- If the problem persists, further diagnostics may be necessary to identify any underlying issues with the ECM or sensor circuit.
Cost to Fix P0187 1999 Ford F150
The typical repair costs for addressing a P0187 code on a 1999 Ford F150 can range from $100 to $300, depending on the specific cause of the issue and the cost of parts and labor. It's important to note that diagnosis time and labor rates at auto repair shops can vary, with hourly rates typically ranging between $80 and $150. Factors such as location, vehicle make and model, and engine type can also impact repair costs. It is advisable to consult with a trusted mechanic or repair shop for a more accurate estimate based on your specific circumstances.
Tech Notes for P0187 1999 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.
