Troubleshoot p1860 code. The P1860 Saturn diagnostic trouble code (DTC) specifically refers to the Transmission Control Module (TCM) detecting an issue with the Torque Converter Clutch (TCC) Pulse Width Modulated (PWM) Solenoid Circuit. DTC P1860 and P1886 indicate transmission control problems, often linked to the torque converter clutch solenoid or wiring faults. Bad TCC PWM solenoid Inspect the TCC PWM solenoid and its wiring for any damage or corrosion. This guide provides an approach for the home mechanic to correctly identify the cause of the P1860 code and perform the necessary repairs. 2. The solenoid attaches to the control valve body within the transmission. The condition of the transmission fluid is the first thing that should be considered when diagnosing a P1860 DTC.

The P1860 code for Oldsmobile specifically refers to an issue with the TCC (Torque Converter Clutch) PWM (Pulse Width Modulation) Solenoid Circuit Electrical. Make: GMC Code: P1860 Definition: TCM PWM Solenoid Circuit Malfunction (4L60-E) Description: Engine started, engine runtime over 5 seconds, system voltage over 10. swkphl smv nokv qqzxafn lsyh pjkz mjc eqzmw nblye plrj
