P174E Code - Output Shaft Speed / ABS Wheel Speed Correlation
Quick Answer
The P174E code detects a fault when the Anti-Lock Brake System (ABS) module and the Transmission Control Module (TCM) have different Vehicle Speed Sensor (VSS) values. Common causes include Faulty Vehicle Speed Sensor (VSS), Vehicle Speed Sensor (VSS) harness is open or shorted, Vehicle Speed Sensor (VSS) circuit poor electrical connection. 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.
