P041E — EGR temperature signal intermittent sensor 2

System: Powertrain  |  Type: Generic (OBD-II Standard)  |  Make: Generic

About P041E

P041E is a generic (obd-ii standard) powertrain diagnostic trouble code. It belongs to the P-prefix family of codes, which covers engine, transmission, emissions, or fuel-system faults.

When P041E is stored, the module has detected a sensor-related fault — the reported value from the named sensor is out of spec.

Scanning & clearing: A generic OBD-II scan tool will usually read and clear powertrain (P) codes. For live data, freeze-frame capture, and bi-directional tests you may need a more capable scan tool that supports the vehicle's ECM protocol.

Because P041E is a generic OBD-II code, its base definition is shared across manufacturers. The specific diagnostic steps, reference values, and repair procedures can vary by vehicle, and the TaT Diagnostic Assistant includes verified procedures submitted by working technicians.

Code Information

The P041E fault code is set when the Engine Control Module (ECM) detects an intermittent signal from the Exhaust Gas Recirculation (EGR) temperature sensor 2. This intermittent or erratic signal indicates a sporadic connection or signal transmission issue, suggesting potential problems with the sensor itself, its wiring, or its connection to the ECM. The EGR temperature sensor 2 is critical for monitoring the temperature of exhaust gases within the EGR system, which is important for maintaining efficient engine operation and controlling emissions. An intermittent signal can lead to inconsisten...
