About P024E

P024E 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 P024E is stored, the module has detected a signal or supply voltage lower than the expected operating range; 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 P024E 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 P024E fault code is set when the Engine Control Module (ECM) detects that the signal from the intercooler bypass position sensor for Bank 1, Sensor 1, is lower than the expected range. This low signal condition suggests a potential short to ground or an issue within the sensor itself, causing it to output a signal voltage that is insufficient. The ECM uses this sensor to monitor the position of the intercooler bypass valve, and a low signal can lead to incorrect turbocharger system management.
