P2610 Code: ECM/PCM Engine Off Timer Performance

Reading Time: 3 minutes

An OBD-II code is designed to tell you possible issues in your vehicle. For you to resolve one, you must first know what it means. If you’re having trouble figuring out what a P2610 code means and how to clear it, you’ve come to the right place. This short guide will give you what you need to know about code P2610.

What Does the P2610 Code Mean?

Diagnostic Trouble Code (DTC) P2610 stands for “ECM/PCM Engine Off Timer Performance.” It means there is a malfunction in the engine control module (ECM) or powertrain control module (PCM) regarding an inability to identify the state of an engine. More specifically, it points to not being able to detect the length of time in which the engine has been turned off.

The vehicle has either the ECM or PCM as its engine controller, which relies on signals from the engine to identify how long the engine has been shut off. In many cases, the control module will use the engine coolant temperature sensor signal to determine how long the engine has stopped operation.

The P2610 code is stored once the ECM or PCM fails to access this timer. The malfunction indicator lamp (MIL) may also be illuminated to indicate the issue. The MIL also typically activates for multiple failed ignition cycles.

Note: The definition of code P2610 may differ depending on the vehicle manufacturer. Consult the appropriate repair manual or repair database for the exact code definition.
