What is the OBD II fault code p0563?

END OF SPECIAL NOTES. OBD II fault code P0563 is a generic code that is sometimes defined as “System voltage – high”, but more commonly as “ECM/PCM Power source circuit- unexpected voltage”.

What causes a p0563 voltage to go up?

The most common causes of P0563 are defective batteries and alternators, but other possible causes could include the following- Damaged, burnt, shorted, and/or corroded wiring and connectors, including corrosion of the battery terminals High resistances caused by poor connections between the battery terminals and battery posts

When does a PCM set the code p0563?

Regardless of the actual wording of the definition though, code P0563 is set when the PCM (Powertrain Control Module) detects an abnormal voltage from either the charging system, or the battery, and sometimes both.

How much does it cost to diagnose p0563 voltage regulator?

The voltage regulator is part of the alternator. The cost to diagnose the P0563 code is 1.0 hour of labor. The auto repair’s diagnosis time and labor rates vary by location, vehicle’s make and model, and even your engine type. Most auto repair shops charge between $75 and $150 per hour.

What happens when a p0563 system voltage is too high?

If the voltage is too high, a fault code will be set. This is strictly an electrical issue. Troubleshooting steps may vary depending upon manufacturer, type of charging system control and wire colors. Symptoms of a P0563 engine code may include: Engine may not start or if it does start, may stall out and die

What does p0563 mean on a check engine light?

P0563 is a diagnostic trouble code (DTC) for “System Voltage High”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic.
