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

About P2080

P2080 is a generic (obd-ii standard) powertrain diagnostic trouble code recorded for Land Rover vehicles. It belongs to the P-prefix family of codes, which covers engine, transmission, emissions, or fuel-system faults.

When P2080 is stored, the module has detected a plausibility fault — the measured value is in the electrical range but is not consistent with expected operating behaviour; a bank-specific fault, meaning it applies only to one cylinder bank of a multi-bank engine; and 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 P2080 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

DTC P2080:64 is set by the Engine Control Module (ECM) when the exhaust gas temperature (EGT) signal from Bank 1, Sensor 1 is determined to be implausible compared with expected exhaust temperature models and operating conditions. The EGT sensor is a thermistor whose resistance changes with temperature, allowing the ECM to monitor exhaust heat for component protection and aftertreatment control. The fault is logged when the sensor signal is outside the normal calibrated range, changes at an unrealistic rate, or does not correlate with related inputs such as engine load, fuel quantity, boost pr...
