About P0095

P0095 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 P0095 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 P0095 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 P0095 code indicates a malfunction in the circuit of the Intake Air Temperature (IAT) Sensor 2. This sensor is responsible for measuring the temperature of the air entering the engine's intake system. The Engine Control Module (ECM) relies on this data to make adjustments to the fuel injection and engine timing. The ECM sets this code when it detects a problem in the IAT Sensor 2 circuit, such as an open or short circuit, which can affect engine performance and efficiency.
