P0657 Jeep Code - Solenoid Supply Voltage Circuit

Quick Answer

The Powertrain Control Module (PCM) monitors the transmission solenoid circuits by supplying voltage to the solenoids through this circuit, then checking for voltage returning from the solenoids through each of the individual solenoid control wires. Common causes include Faulty Transmission Solenoids, Transmission Solenoids harness is open or shorted, Transmission Solenoids 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.

Code P0657 Jeep Description

The Powertrain Control Module (PCM) monitors the transmission solenoid circuits by supplying voltage to the solenoids through this circuit, then checking for voltage returning from the solenoids through each of the individual solenoid control wires. If one of the solenoid return circuits does not have the correct voltage returning to the PCM, the PCM will set a code for that solenoid.
However, DTC P0657 sets when ALL of the solenoids do not have the correct voltage returning to the PCM all at the same time.
