ECU 000105.04 is activated when the input voltage at the exhaust gas recirculation (EGR) mixed air temperature sensor falls below the minimum specified level, typically indicating a short to ground. This fault can lead to inaccurate temperature readings, which are crucial for the ECU to manage the EGR system effectively.

Error code ECU 000105.03 indicates that the input voltage at the exhaust gas recirculation (EGR) mixed air temperature sensor is too high, suggesting a potential short to a 12-volt source. This could lead to erroneous temperature readings, affecting the EGR system’s ability to properly manage engine temperatures and emissions.

This error code, ECU 000105.00, occurs when the mixed air temperature in the exhaust gas recirculation (EGR) system significantly exceeds expected levels. This condition suggests an abnormal increase in the intake manifold air temperature, potentially due to EGR system malfunctions, such as clogging or operational faults.

Error code ECU 000103.08 is triggered when the turbocharger speed reported by the sensor is impossible under the current operational conditions. This could indicate a fault with the sensor or its data processing pathway.

READ MORE

ECU 000103.06 indicates that the current in the turbocharger speed sensor’s wiring is excessively high. This might be due to a short circuit or other electrical faults that cause an overload, potentially damaging the sensor and associated wiring.

READ MORE

The error code ECU 000103.05 is triggered when there is abnormally low current in the turbocharger speed sensor’s wiring, suggesting high circuit resistance or an open circuit. This condition can result from damaged wires, poor connections, or a fault within the sensor itself, affecting the sensor’s ability to accurately relay turbocharger speed data.

READ MORE

This error code, ECU 000103.02, indicates that the turbocharger speed signal received by the ECU is invalid or erratic. This fault might be due to issues with the turbocharger speed sensor or its wiring, causing unreliable data transmission to the ECU.

READ MORE

The error code ECU 000103.00 signifies that the turbocharger speed is excessively high, surpassing the normal operational limits. This condition indicates that the turbocharger is operating at a speed higher than what is considered safe, potentially due to a malfunction in the turbo system or control electronics.
