See the error code popping again and again? Don’t stress at all, we are here to solve all your problems and queries. Here we have written down all you need to know about the error code P2553. The transmission control module (TCM) situated inside the powertrain control module (PCM) houses the diesel engine power monitor (DEPM) strategy. At the time when there is no power demand from the accelerator pedal position (APP) sensor, the DEPM monitors the engine RPM.

Under general engine idle operation, the engine RPM value must always be lower than the DEPM RPM value. Incase the DEPM limit is not exceeded by the engine RPM, the crankshaft and the camshaft output signal sent to the PCM to the fuel injector control module (FCIM) are disabled by the DEPM.

What causes this problem with Throttle/Fuel Inhibit Circuit Range/Performance?

• Concerns related to the operations of the fuel injection system (generally within a diesel powered vehicle)
• Voltage abnormality in the fuel injection system (detected by the ECM)

• First and foremost, the trained technician should use a specialized scan tool (differing from those in technological abilities of scan tools in auto part stores). It should be noted that these specialized scan tools can only be found with trained technicians. This tool is used to gather and analyse data from the engine control module. This is used by the technician to narrow down the causes of the error code P2553.
• Then perform a visual inspection of the all the electrical components to pin down the possible causes leading to this error code.
• Now, if you have been able to find the root cause successfully, make sure you repair or replace it. Next, other tests should be performed including other scan to ensure that the problem has been solved completely. 

Common Mistakes When Diagnosing the P2553 Code

Here we have listed a few common mistakes that should be avoided while performing a diagnosis of the error code P2553 code:

• Ignoring to check the voltage discrepancies present in the fuel injection system
• A failure in performing a careful visual inspection of the fuel injection system and all the other linked components
• A failed attempt at clearing the error code P2553 after all the repairs have been performed
• One should also be careful and avoid performing unnecessary adjustments or repairs in the fuel supply system
