P2D32Intake Manifold Tuning Valve Control Circuit Driver Current/Temperature Too High Bank 1
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- How the car detects it
- P2D32 is an electrical self-protection code: the power stage that drives the motor of intake manifold tuning valve 1 has reported excessive current or overheating. Smart drivers watch both values internally and switch off before damage. Unlike P0661 and P0662, which describe a line shorted low or high, this code comes from the driver itself, often because the motor is overloaded. GM applies it to the LT6 V8 of the Corvette Z06 (model years 2023 and 2024), where servo-operated valves connect the two intake plenums. Tables 23OBDG07 and 24OBDG07 store it when the stage flags overcurrent or overtemperature for 1 s with battery voltage between 9 and 17.5 V; MIL after two trips. Valve 2 has a separate GM code. Look for a jammed or stiff valve, a shorted motor winding or chafed wiring.
- What you may notice
- Check engine light
- Tuning valve stays in one position, with less torque in some rev ranges
- Code may return soon after clearing if the valve stays jammed
- Likely causes
- LikelyValve jammed or stiff, so the motor draws excessive current
- PossibleInternal short in the actuator motor
- PossibleChafed control wiring touching ground or another circuit
- RareFaulty driver stage in the engine control module
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
