P0871 on Dodge
Transmission Fluid Pressure Sensor/Switch "C" Circuit Range/Performance
P0871 on Dodge vehicles indicates transmission fluid pressure sensor/switch "c" circuit range/performance. Au7o has documented this code across 1 Dodge model — most commonly on Dart. This code sets when the transmission control module receives a signal from transmission fluid pressure sensor/switch C that is out of the expected range or implausible for the current conditions. This sensor monitors hydraulic pressure inside the transmission, which the module relies on to control clutch apply and shift quality. Symptoms can include harsh, delayed, or erratic shifts, slipping, or the transmission entering a failsafe mode. The cause is typically the sensor, actual fluid pressure problems, or the wiring. Typical repair costs on Dodge range from $600 to $1,200, depending on the specific model and root cause.
Common Causes of P0871
- •Faulty transmission fluid pressure sensor/switch C
- •Low or degraded transmission fluid
- •Internal hydraulic leak or low line pressure
- •Stuck or faulty pressure control solenoid
- •Wiring or connector issues
- •Valve body wear or contamination
- •Faulty transmission control module (less common)
P0871 on Dodge by Model
Dodge Dart(1 issue)
- Transmission Control Module (TCM) Failure on 2.4L Automatic2013-2016
The 2.4L Dart paired with the Aisin 6-speed automatic experiences TCM failures that cause erratic shifting, failure to shift, and limp mode. The TCM mounted on the transmission is exposed to heat and vibration, leading to internal circuit board failures. Unlike the DDCT issues on 1.4T models, this affects the conventional automatic transmission.
