Why Ford DTC P1670 Matters for Safety and Driveability

If you’re a body shop, collision repair center, used car dealership, or a vehicle owner dealing with a salvage or rebuilt title Ford, the diagnostic trouble code (DTC) P1670 is one you shouldn’t ignore. This code directly affects your vehicle’s ability to interpret steering input, which is critical for Advanced Driver Assistance Systems (ADAS) and overall road safety. Winter driving in Texas — particularly in Denton County — makes this issue even more urgent as a malfunction in your electronic steering or safety systems can lead to serious handling issues or even airbag misfires.

What Does Ford DTC P1670 Mean?

DTC P1670 on Ford vehicles indicates a fault in the steering angle sensor circuit — specifically, a failure in communication between the Body Control Module (BCM) and the steering angle sensor. This sensor is a crucial component of your ADAS and stability control systems, helping determine the direction the driver intends the vehicle to go. If this sensor fails to communicate properly with the control units, systems like lane-keeping assist, electronic stability control, and airbag deployment logic may be compromised.

Common Causes of P1670 in Ford Vehicles

Here are several common triggers for the P1670 code:

Improper installation or misalignment of the steering angle sensor
Open or short circuits in the wiring harness between the BCM and the sensor
Faulty connections at BCM terminals (3V, 3W, 3S, 3T, 3X, 3N)
Short to ground or power in the signal wires
Internal failure of the steering angle sensor
Malfunction within the BCM itself

These issues are especially common in salvage or rebuilt vehicles where root repairs or wire harness damage may have gone unnoticed or improperly addressed.

Symptoms You Might Notice

Whether you run a used car dealership or a collision repair shop — or even if you’re an individual buyer — here are signs that may indicate DTC P1670:

Airbag or ABS warning lights on the dash
Inconsistencies or failure in steering assist
Lane-departure systems not functioning
Vehicle veering during turns or unexpected handling issues
Failure to calibrate ADAS systems

Experiencing any of the above in Denton County? It’s time for a detailed vehicle diagnostic!

Why Professional Help Is Critical

A trouble code like P1670 isn’t something to ignore or DIY. Miscommunication between the BCM and steering angle sensor directly affects how your airbag deploys and how effective your ADAS systems are in preventing accidents. General mechanics may miss key resets, electrical diagnostics, or required calibrations.
