About P2015

P2015 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 P2015 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 P2015 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 intake manifold runner control system uses movable flaps inside the intake manifold to alter effective runner length or induce swirl, improving cylinder filling at low engine speed while allowing better flow higher in the range. A position sensor, usually a potentiometer or hall effect device integrated into the actuator, reports actual flap position to the ECM so it can confirm the commanded movement actually occurred. P2015 sets when that position signal is present but implausible, meaning the reported position does not agree with the commanded position or fails to change as expected dur...
