What the P0613 code means

The P0613 code is the same kind of processor fault as P0606, but in the automatic transmission computer. It can make the transmission go into limp mode.

Before you decide the computer is bad, always check its power supply and grounds. Low voltage, a loose terminal or a corroded ground cause internal errors that go away once they are corrected. It is also worth looking for software updates from the manufacturer, because many of these codes are resolved by reprogramming the computer without replacing it.

If the computer has to be replaced, keep in mind that it almost always needs programming: VIN, immobilizer, option configuration and, on many vehicles, relearn procedures afterward. A used computer that has not been programmed can leave the vehicle unable to start.

P0613 code symptoms

  • Check engine light on.
  • The engine may not start or may run in limp mode.
  • Other codes at the same time in several systems.

Likely causes of the P0613 code

  1. Computer power supply or ground: low voltage or a connection with resistance.
  2. Battery disconnected or discharged, a cause that matters most for the keep alive memory code P0603.
  3. Software with bugs. Manufacturer updates exist.
  4. Moisture or corrosion inside the computer from deteriorated case seals or water getting in through the engine bay.
  5. Internal failure of the computer. Only after you rule out everything above.

How to diagnose the P0613 code step by step

  1. Clear the code and see whether it comes back. Some are caused by a one-time event, such as a discharged battery.
  2. Measure the voltage at the computer power pins and compare it with the battery.
  3. Measure the voltage drop on the grounds. It should be under 0.1 V with a load.
  4. Look for technical service bulletins and software updates.
  5. Inspect the computer connector for moisture, corrosion or bent pins.

How to fix the P0613 code

  • Correct the power supply and the grounds.
  • Reprogram or update the computer.
  • Replace the computer only if everything above is good, and program it.
  • Clear the codes and verify.

Technical reference data

  • Supply voltage: battery voltage, with less than 0.2 V of drop.
  • Programming needs a stable voltage, so use a battery maintainer.
  • Reference values only: check the manufacturer data for your vehicle.

Brand-specific notes

Frequently asked questions about P0613

Can I drive with the P0613 code?
It depends on the symptoms. If the vehicle runs normally, drive with caution. If the transmission goes into limp mode, take the vehicle to a shop.
Does the computer have to be replaced?
Not always. Many times it is the power supply, a ground or the software.
Does a used computer work?
Only if it is programmed correctly for your vehicle.
How much does it cost to fix P0613?
From $0 (if it was the battery) up to $1,500 if the computer has to be replaced and programmed.
What does the P0613 code mean?
The P0613 code is a generic OBD2 code for a transmission control module processor fault. The transmission computer detected an error in its own processor.
What is the most common cause of P0613?
Low voltage or a poor ground at the transmission computer, or software that needs an update.
