P2D32: Intake Manifold Tuning Valve Control Circuit Driver Current/Temperature Too High Bank 1

The output driver for the intake manifold tuning valve actuator on bank 1 reports current or junction temperature above its protection threshold.

Bank 1 is the side of the engine with cylinder 1. Inline engines only have this bank.

Most likely causes

• Tuning valve actuator jammed
• Control wire shorted to ground

What to check, in order

Start with the simplest. You can tick off each step.

1. Check the vacuum hoses and the connector
2. Check the sensor's ground and make sure the signal wire is not receiving voltage from another circuit.
3. Watch the actuator's movement with the scanner
4. Inspect the manifold for carbon buildup
5. Replace the actuator if it does not follow the command

Good to know

• Repair difficulty: medium
• It can trigger limp mode.
• It affects emissions.

What each character of P2D32 means

• P: Powertrain: engine and transmission
• 2: Generic code: same on every make
• D: Subsystem depends on the code range
• 32: Specific fault in that system

Frequently asked questions

Can I keep driving with code P2D32?

You can drive in moderation. Get it repaired soon, because a loose flap can cause major damage on some engines.

What causes code P2D32?

The most common causes are: tuning valve actuator jammed; control wire shorted to ground.
