P176D: Intermediate Speed Sensor Circuit High Voltage
2 vehicles · 1 makes · $600-$4,500 repair
Most Reported On
P176D is an OBD-II diagnostic trouble code meaning “Intermediate Speed Sensor Circuit High Voltage.” P176D is a manufacturer-specific powertrain code; its most common definition (GM and the major code databases) is "Intermediate Speed Sensor Circuit High Voltage," meaning the transmission control module detected a higher-than-expected voltage on the intermediate/input shaft speed sensor circuit. The sensor reports rotational speed inside the transmission so the TCM can select the correct gear, so a faulty signal can affect shift quality. Note the meaning varies by brand — on VW/Audi it relates to gear selector 4 not being regulated, and on some Jeep/Chrysler applications it indicates transmission fluid temperature too high — so confirm against the specific vehicle. This code is most commonly reported on 2017-2025 Volkswagen Golf R (MK7.5 R (DSG), MK8 R (DSG)), and 2019-2023 Volkswagen Arteon (2.0 TSI, 2.0 TDI, R, SEL, SEL Premium R-Line), with repair costs ranging from $600 to $4,500.
