I recently had my engine coolant temperature sensor replaced twice, but the P0119 diagnostic code continues to appear. Despite the replacement, the issue persists. What are the next steps I should take to diagnose and resolve this problem? The P0119 code indicates an abnormal engine coolant temperature reading, so I'm looking for reliable troubleshooting methods specific to the 2004 Ford F150 with a 5.4L V8 engine.

Refer to this detailed explanation of P0119: https://www.obd-codes.com/p0119 This code typically points to issues with the coolant temperature sensor or its wiring, so ensure connections are secure and check for corrosion. Also verify that the sensor is properly seated and not damaged.

I agree—this sounds like a process of elimination. I'll systematically go through each potential cause listed in the P0119 troubleshooting guide, starting with wiring harnesses, ground connections, and sensor calibration. Thanks for pointing me to that resource—it's very helpful.
