John Deere 000107.15 – ECU: Air Filter High Pressure Difference

The Engine Control Unit (ECU) has detected a high-pressure differential across the engine air filter, signaling a restriction. This indicates that the air filter is dirty or blocked, causing a drop in air pressure as it enters the engine. This condition may negatively affect engine performance and requires immediate attention.

1. 1

   Visually inspect the air filter housing and intake system for obvious blockages such as debris, nests, or collapsed intake hoses

2. 2

   Remove and inspect both the primary and secondary air filters for dust, dirt, or other particulates

1. 1

   Clean or replace the air filter

   If the primary filter is dirty, clean it according to manufacturer guidelines or replace it. Replace the secondary air filter if it appears dirty, as it is generally not serviceable.

2. 2

   Clear the fault code

   After replacing the filter, start the engine and see if the fault code clears. On some machines, you may need to cycle the key switch.

3. 3

   Inspect the sensor and wiring

   If a new filter does not resolve the issue, inspect the air filter restriction sensor (typically located on or connected to the air filter housing via a hose) and its wiring harness for damage, corrosion, or loose connections.

4. 4

   Test the sensor

   If the wiring appears intact, test the sensor's output to determine if it is functioning correctly.

5. 5

   Replace the sensor

   If the sensor is determined to be faulty, replace it with the correct model-specific part.
