P3467Cylinder 9 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
- With P3467 the control line of the cylinder 9 deactivation or intake valve actuator reads too low, which usually means it is touching ground. No manufacturer documents this code publicly; J2012 reserves the codes for cylinders 9 to 12 for engines with more than eight cylinders. Twelve-cylinder engines with cylinder shut-off do exist, for instance Mercedes' M137 and Lamborghini's Aventador V12 introduced in 2012, but no published diagnostic list connects this number to them. GM's matching test on its V8 engines looks for less than 0.5 ohm to ground with the driver switched off and only runs above 11 V and 425 rpm. On a low-side driven solenoid, a ground fault can keep the coil energised, so the cylinder may drop out when it should fire. Siblings: P3465 open circuit, P3468 short to voltage.
- What you may notice
- Check engine lamp on
- Cylinder deactivation disabled
- Possible misfire on cylinder 9 if the actuator stays energised
- Likely causes
- LikelyCylinder 9 control wire shorted to ground
- PossibleInternal short in the cylinder 9 solenoid
- RareMoisture in the solenoid connector
- RareFaulty driver in the engine control module
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
