P3476Cylinder 10 Deactivation/Intake Valve Control Circuit High
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- How the car detects it
- P3476 is logged when the control circuit of the cylinder 10 deactivation or intake valve actuator sits at too high a level, usually a short to a battery-fed wire found while the output is active. No manufacturer documents this code publicly; J2012 reserves the codes for cylinders 9 to 12 for engines with more than eight cylinders. On the V10s that offer shut-off, Audi describes the bank being stopped by cutting fuel injection and ignition in the upper gears, so cylinder 10 has no valve actuator there. A twelve-cylinder engine with valve switching, such as Mercedes' M137 with its oil-pressure solenoid pack, is the kind of design this code was written for. The control module then usually blocks deactivation for the rest of the trip. Electrical siblings: P3473 and P3475.
