Code P1702 Mercury Description
The P1702 code for Mercury vehicles indicates a Transmission Range Circuit Failure. This means that the Transmission Range Sensor (TRS) is not functioning properly, causing issues with the transmission's ability to shift gears accurately. The TRS is responsible for sending signals to the vehicle's computer to determine the correct gear position based on the driver's selection. When this circuit fails, it can lead to erratic shifting, difficulty in shifting gears, or the transmission not engaging at all.
Common Causes of P1702 Mercury
- Faulty Transmission Range Sensor (TRS)
- Damaged wiring or connectors
- Corrosion in the TRS circuit
- Issues with the transmission control module
- Electrical problems within the transmission system
Symptoms of P1702 Mercury
- Erratic shifting
- Difficulty in shifting gears
- Transmission slipping
- Inability to shift into certain gears
- Dashboard warning light illuminating
