P0385 and P0741 Diagnostic Issues on GMC 2500HD with 6.0L Engine

Model: GMC 2500HD Fault Code: P0385 Posted: 2015-02-23 19:25

My GMC 2500HD truck has been displaying fault codes P0385 and P0741. The vehicle runs smoothly overall, but occasionally takes 5 to 8 seconds to start, while other times it fires up immediately. It is equipped with a 6.0L V8 engine and an automatic transmission. Any insights into what might be causing these codes or the inconsistent starting behavior?

Inspect the Crankshaft Position Sensor 'B' and its associated wiring circuit. Additionally, check the Torque Converter Circuit and solenoid for proper operation and potential faults.
