Code Definition

P024A — Intercooler bypass control solenoid Circuit malfunction - Bank 1

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

About P024A

P024A 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 P024A is stored, the module has detected a bank-specific fault, meaning it applies only to one cylinder bank of a multi-bank engine.

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 P024A 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 P024A fault code is set when the Engine Control Module (ECM) detects a malfunction within the control circuit of the intercooler bypass control solenoid for Bank 1. This code is triggered when the ECM observes an electrical fault, such as an open circuit, short to ground, or short to voltage in the solenoid's control circuit. The ECM monitors the electrical performance and response of the solenoid to ensure efficient turbocharging system operations.
