Understanding P0562 on Acura TL
The P0562 code on an Acura TL indicates a charging system low voltage issue. This means that the system voltage has been detected as being below 10 volts for a solid minute. Typically, with the engine running, the system voltage should be between 14.1-14.4 volts. The code is often caused by a bad alternator, which can result from issues such as a loose or missing alternator drive belt, a faulty alternator, a defective battery, or an open or short system voltage circuit.
Symptoms and Diagnosis
When this code is triggered, the battery voltage detected by the Engine Control Module (ECM) is less than a calibrated value. Symptoms of this issue may include low battery charge, a discharged battery, and the alternator not providing adequate charge to the battery. The diagnosis typically requires 1.0 hour of labor, and the specific diagnosis time and labor rates at auto repair shops can vary based on factors such as the location, make and model of the vehicle, and even the engine type. Most auto repair shops charge between $75 and $150 per hour for this diagnosis.
Maintenance and Troubleshooting
For Acura TL owners, understanding the charging system is crucial for diagnosing problems and finding a good mechanic. The charging system includes wiring, a battery, and a voltage regulator. The warning light on the dashboard of the Acura TL can indicate when the battery is running low on voltage, signaling potential issues with the charging system.
In summary, the P0562 code on an Acura TL points to a low voltage issue within the charging system, often caused by problems with the alternator, battery, or associated wiring. It’s important to have the system diagnosed by a professional to address the specific cause of the low voltage and prevent potential issues with the vehicle’s electrical system.

P0562 (System Voltage Low) — What It Means
A P0562 code stored in the PCM means that the system voltage is dipping below 10 volts for 60 seconds at a time or more when the engine is running.
How do I fix code P0562?
For example, in certain Dodge vehicles, a common fix for a P0562 code is to replace the battery—provided that the underlying cause was a bad battery, of course.
How do I know if it’s my battery or alternator?
One of the most obvious signs is if the car dies after a jump start. The alternator should provide enough current to keep the vehicle running even with a bad battery. If it doesn’t, then your alternator needs to be examined.
Does charging system warning mean I need a new battery?
It could indicate that your battery is damaged or worn out, or that the charging system is malfunctioning in some way. When your vehicle is having these issues, you’ll often notice other bad battery symptoms, too.
What causes the symptoms of P0562 code?
Usually around 14 volts. And yogurt computers not seeing this is seeing that below this range. And so it’s sending out this code. And it’s gonna have to be troubleshooting. No why.
Can a bad battery cause a P0562 code?
Blown fuses are another common cause when dealing with a P0562 code and worn-out car batteries. If something is causing a large battery drain, or if there is defective wiring connecting the alternator to the PCM, you will notice a P0562 code error.
What is the code for bad alternator?
HERE’S HOW TO DIAGNOSE A FAILING ALTERNATOR
If you have a “Check Engine” light on, connect a code reader to the diagnostic port. If you find code P0562, you very likely have a failing alternator (note that codes may vary by vehicle make/model/year). Get it checked out before it fails entirely.
Can a bad battery cause a p0562 code?
No. While a faulty alternator could cause this code, there are several other possible causes such as : poor grounds, defective voltage regulator, faulty wiring, defective battery and others.
How do you tell if its your battery or your alternator?
An effective method to determine whether it’s your battery or alternator that’s gone bad is to connect jumper cables from a running vehicle’s battery to yours. After a few moments, try starting your vehicle. Once it’s started, remove the jumper cables — if your engine stalls, your alternator has probably gone bad.
Why does my check charging system light come on and off?
But if the battery light comes on and off while driving or stays lit as you drive, your battery or the charging system may be at fault. The battery light on your dash could indicate a minor issue like built-up corrosion on the battery’s terminals or a more complex problem like a failing alternator.
