P3480Cylinder 10 Exhaust Valve Control Circuit High
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- How the car detects it
- If the control line of the cylinder 10 exhaust valve actuator is held near supply voltage, the engine computer stores P3480. No manufacturer documents this code publicly; J2012 reserves the codes for cylinders 9 to 12 for engines with more than eight cylinders. A ten-cylinder engine has no cylinder 11 or 12, so P3480 is the last exhaust-valve code a V10 could ever use; the R8 V10 still does without it because its shut-off works through injection and ignition. Sorting out a high circuit means looking for a wire chafed against a feed, a backprobe left in a connector, or a coil with shorted windings. P3477 (open) and P3479 (low) are the other electrical faults of this actuator, P3476 the intake equivalent on cylinder 10.
