Code Definition

P115E — Intake Manifold Runner Control Circuit High (Bank 2)

System: Powertrain  |  Type: Manufacturer-Specific  |  Make: Toyota

About P115E

P115E is a manufacturer-specific powertrain diagnostic trouble code recorded for Toyota vehicles. It belongs to the P-prefix family of codes, which covers engine, transmission, emissions, or fuel-system faults.

When P115E is stored, the module has detected a signal or supply voltage higher than the expected operating range; and 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.

P115E is a manufacturer-specific code. The same code string on a different make may have a different meaning. Always confirm the code's definition against the vehicle's service information for the specific make and model under test.

Code Information

This DTC is set when the Engine Control Module (ECM) detects that the voltage in the control circuit for the Intake Manifold Runner Control (IMRC) actuator on Bank 2 is higher than the specified threshold. The IMRC system adjusts the position of intake manifold valves to optimise airflow for varying engine conditions. A high circuit voltage usually indicates an open circuit, poor ground, or internal actuator failure.
