Most auto repairs shops charge between 75 and 150 per hour. The auto repair labor rates vary by location, your vehicle's make and model, and even your engine type. If the software is already up-to-date, I would recommend starting with an oil change using oil with the correct viscosity.

The cost of diagnosing the P0462 DODGE code is 1.0 hour of labor. There appear to be two software updates to address the false detection of the P1521 DTC they are on Technical Service Bulletins (TSBs) 18-008-08 and 18-035-05. Lastly, this condition could also be caused by a PCM software issue. This code could also be set if there is a problem with the engine's internal oil pressure. Engine oil viscosity could be incorrect due to the wrong engine oil being added or oil contamination (with fuel or coolant). The description for Diagnostic Trouble Code (DTC) P1521 is 'Incorrect Engine Oil Type.' The Powertrain Control Module (PCM) is able to identify engine oil viscosity using oil pressure and oil temperature sensor inputs and will set this DTC if the viscosity is determined to be incorrect.
