P0562 PONTIAC Possible Causes
- Low battery charge
- Battery defective
- Loose or missing alternator drive belt
- Faulty alternator
- Open or short system voltage circuit
How do I fix code P0562 PONTIAC?
Check the “Possible Causes” listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins.
Tech Notes
- Start by recharging or replacing the battery.
Cost of diagnosing the P0562 PONTIAC code
The cost of diagnosing the P0562 PONTIAC code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle’s make and model, and even your engine type. Most auto repairs shops charge between $75 and $150 per hour.
When is the code detected
The Powertrain Control Module (PCM) has detected that the electrical system voltage level is too low.
Possible Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Slow engine start
- Low battery power
P0562 PONTIAC Description
The Powertrain Control Module (PCM) continuously monitors the system voltage. The system voltage information is taken from the PCM’s ignition feed circuits. Voltages below 8.0 volts or above 17.1 volts causes improper system operation and/or component damage. If the system voltage is low the PCM raises the idle speed in order to increase the generator output. The PCM disables most outputs to protect the hardware if the system voltage is high. A scan tool may not display data if system voltage is outside this range.
