Guide To P0563 OBD Error Code Solutions

<<See All OBD Codes

The OBD Code P0563 is set when the ECM detects an out of range voltage reading. The Engine Control module of a vehicle receives power from the battery when the car is off. This allows it to perform certain functions, one of those is data storage. It assumes that a power supply circuit is at fault and hence, automatically triggers this OBD error. You will also notice the ‘Service Engine Soon’ light to switch on as well. The voltage variation could be due to multiple causes, like the battery, or the alternator or other components in the starting or charging system.

Every vehicle charging system is responsible for maintaining a certain voltage level when the engine is on. If the ECM observes that the battery voltage drops below 10V, it will proceed and set code P0563

What causes this problem with the System Voltage High

Below are some causes to this error:

• High resistance found in the cable between the battery and alternator
• The circuit between the alternator and control module is open or having high resistance
• Unfit alternator
• Failed PCM has failed

Interested in knowing the symptoms to obd code P0563? If yes, then you have arrived at the right place. We at PartsAvatar have listed out few common symptoms associated with this fuel injector problem.

Common Symptoms

• The Malfunction Indicator Light switches on
• Red battery indicator light on
• No shift in the transmission
• Engine not starting as usual or if it does start, stalls out and dies
• Increase in fuel consumption

We have listed out some ways which would help you to correct the occurrence of OBD Code P0563. They are:

• Replace the cables of battery
• Replace current battery with new car battery
• Cleaning the corrosion present at the battery terminals and posts
• Replacing the alternator completely
• Starter has to be replaced
• Replacing the entire PCM

Apart from the fuel injector, you might need to undergo few more replacements. You might need ECM, Control, Module, Malfunction indicator light, Transmission, Charging System, Electrical System, Wiring, Cable, Connector and many other parts. Where to get them from? Well, if you want quality parts, then we can prove to be your dream destination

Here are some easy steps to follow in-order to diagnose this fault code:

• Start by checking the TSB (Technical Service Bulletin) of your vehicle, for any suggestions from the manufacturer to resolve this OBD code.
• A faulty alternator is usually the culprit behind this OBD code. To check this, start the vehicle, turn on the headlights and the blower fan (high speed). This will help load the electrical system, now use the DVOM (Digital Volt Ohm Meter) and check voltage at the battery. The range it should be in is 13.2V to 14.7V. If it is below 12 or above 15.5, you can diagnose the charging system as the problem maker, with focus on the alternator. If the voltage is correct, use the scanning tool to delete all the saved codes and see if error P0563 returns. You can approach a mechanic too for sorting this out, they will give you a print out of the test results, and the whole thing won’t cost much.
• If the code doesn’t return after clearing the data, it must’ve been an intermittent code or form the history/memory. You can conclude your diagnosis. However, if the code returns, you will have to inspect the PCM.
• Locate the PCM and start off by visually inspecting the connector and wiring around it. See if they are all in good shape, any scraping, rubbing, bare wires, burn spots or melted plastic should not be there. Now, pull these connectors parts completely and proceed to inspecting the terminals found inside the connectors. Are they burned or have a green tint? if yes, that indicates corrosion. You will have to sort that out using an electrical contact cleaner and a plastic bristle brush. Once the parts have been cleaned and are dried use electrical grease where the terminals contact.
• Clear the codes once again and wait to see if the P0563 code returns. If it doesn’t then it was the connections that were your problem. If the code returns, you’ll have to now check the voltages going to the PCM.For this, you will have to disconnect the negative battery cable at the battery, and also the disconnect the harness going to the PCM. Now, reconnect the battery cable, and turn on the ignition switch. Use the DVOM and test the ignition feed circuit of the PCM (Red lead to the PCM ignition feed, and black lead to a solid ground).
• Observe the battery volts, if they are less then repair the wiring going from PCM all the way to the ignition switch, however if that’s okay, you’ll have to ensure the ground is good at the PCM. For this connect a test light of 12V battery red terminal i.e. positive and touch the other end of this light to the ground circuit of the PCM ignition feed. If the light doesn’t light up, then the circuit is faulty. If it lights up, shake the wiring harness going to the PCM and notice if the light flickers. A flickering light is indicative of a loose connection.
• If all prior tests have passed, but the error code persists to come, then it would have to be a failed PCM causing it. If you’re not confident about your conclusion, approach a professional automotive diagnostician and have your PCM installed. This requires it to be programmed to your specific vehicle, so ensure your mechanic has experience in PCM installation.

Common Mistakes When Diagnosing the P0563 Code

The tricky part of this OBD code is to rule out the source of problem. Often times the battery is replaced, when it’s not needed. Or even the PCM is concluded as faulty. This can turn out to be very expensive. It’s mostly the alternator that’s the issue, and hence it’s important to avoid this mistake.
