Error Code P2533: What It Means & What To Do?

<<See All OBD Codes

Do you know how the P2533 error is stored in the vehicle? Keep reading further to know more. Failure of the fuel pump control module is usually known as the ignition switch run/ start position circuit. The battery voltage will be sent to the vehicle’s electrical system when the key is in on position. In order to make sure that the voltage is correct, the battery control module will look after this and if the voltage is too less, then the P2533 error will be set.

The powertrain control module will carefully look after the signal of the ignition switch run position circuit. The error code will be set by the PCM if the ignition switch run position signal goes out of factory specification.

What causes this problem with the Ignition Switch Run/Start Position Circuit?

• Malfunctioning of the ignition switch.
• The ignition switch harness might have a short circuit or you might find an opening.
• The electrical connection might be poor in the circuit of the ignition switch.

1. Powertrain Control Module - A faulty PCM can cause misfiring issues and the engine behavior might also be erratic. If your vehicle is causing misfiring issues, then it is because of a faulty powertrain control module. Shop them from Parts Avatar at best prices online.
2. Ignition Switch - There will be a loss of voltage if the ignition switches are worn out. Get a new ignition switch for your vehicle from PartsAvatar.
3. Battery Control Module - It is always best to replace the damaged high voltage battery control module as they provide information on the charge state, battery health, and voltage which is easily accessible.
4. Starter Motor - Replacing the faulty starter motor can help you to avoid the clicking sound from the engine and the P2533 error can be avoided.
5. Transmission Control Module - Poor fuel economy is an indication of bad TCM. Change it as soon as possible.

Have you ever wondered why is it so important to know the symptoms of the problem? Well, it is extremely essential to know the symptoms of the problem in order to detect it. Keeping this in mind, let’s throw some light on a few common symptoms of OBD error code P2533

Common Symptoms

• Weak fuel economy.
• The wire might be faulty.
• Fuel efficiency will be reduced.
• The engine oil will start showing dilution from the ECU’s attempt to improve the temperature of the engine. In order to increase the exhaust temperature, some vehicle will increase the timing of the fuel injection slightly so that a small amount of fuel can be burnt. This fuel will enter the crankcase and if there is a need to restore DPF, the oil’s service life will be reduced considerably.

To correct this issue, you might need to undergo few replacements for the defective parts such as:

• Fixing the ignition switch which is broken can help in minimizing this error.

Here are some steps which you should follow in order to diagnose this fault code P2533:

• The voltage gets transferred from the battery and cables to almost every system in the vehicle with the help of an ignition switch.
• The voltage which is sent through this ignition switch is called switched voltage and with the help of a mechanized actuator, the cylinder key is turned on.
• The inner portion of the ignition switch will receive battery voltage with the help of fused primary wires and cables.
• As the ignition switch is turned off, systems which operate using switched voltage are successfully defused.
• This helps not only to save battery voltage but also makes transportation comfortable and easy.
• Once the switch is fixed to the accessory or auxiliary position, switched voltage will be sent to the system which is linked with stationary use.
• Activate the starter by fixing the ignition switch in the start position and start the engine.
• The voltage is almost sent to all switched voltage system during run position
• To proceed with the diagnosis, a scanner and DVOM is needed.
• As you diagnose this error, a manufacturer’s service manual will be highly helpful.
• Start the diagnosis by inspecting the wires as well as the connectors.
• Fix the damaged, separated, shorted or eroded wires as needed.
• Recheck the system by clearing the error codes and make sure the repair work is done successfully.
• If each of the wires and connectors works properly, retrieve every one of the stored codes and freeze frame data by fixing a scanner to the diagnostic connector.
• This data can be highly useful to diagnose the erratic conditions which would have helped in the storing of this code.
• Once the error codes are removed, check again to see if the error appears.
• Erratic conditions may persist if the code does not come quickly.
• In an extreme situation, this erratic condition can be quite risky to diagnose and this situation has to be made to worsen before you proceed further.
• Check for battery voltage and ground signals at the ignition switch, if the code shows up again.
• With the help of DVOM check for openings in the ground or battery voltage circuit for continuity and resistance in both the circuits.
• Clear all codes and retest the vehicle to see if any error has occurred.
• Pay close attention to the fuses and fusible links and make sure to locate the reason for the failure of the fuse and fusible links to avoid further damage.
• With the help of the manufacturer’s wire diagram test the circuit for resistance and continuity and relate your findings with that of the manufacturer.
• Fix every one of the circuits, connectors, and components which fails to comply with the manufacturer’s specification.
• Make sure that the repair was successful once the system was re-checked.

Common Mistakes When Diagnosing the P2533 Code

• Fuel pump control module might be faulty.
• Damaged ignition switch.
• An issue might arise due to faulty wires.
