P3475Cylinder 10 Deactivation/Intake Valve Control Circuit Low
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- How the car detects it
- P3475 points to a short to ground on the circuit that controls deactivation or the intake valve of cylinder 10. No manufacturer documents this code publicly; J2012 reserves the codes for cylinders 9 to 12 for engines with more than eight cylinders. The Lamborghini Huracán's V10 runs on five cylinders at light load and the Aventador V12 on six below 135 km/h, yet neither maker publishes code-level diagnostics, and Audi's sister V10 manages without valve actuators. For a sense of the test, GM's eight-cylinder version of the low check needs below 0.5 ohm to ground while the output is off, sampled every 250 ms. Check the wire to cylinder 10 for chafing first, then the actuator itself. P3473 handles an open line, P3476 a short to voltage, P3479 the exhaust counterpart.
