P0029: Exhaust Valve Control Solenoid Circuit Range/Performance — Bank 2
What to do
Usually driveable. Oil condition first, then the solenoid itself.
What this code means
The bank 2 exhaust valve control solenoid is not performing to command, completing the four valve-control codes in this range. As with the camshaft group, the pattern across banks is the diagnostic signal: one bank implicates that bank's hardware, both banks implicate the oil feeding them.
Likely causes
Start here
- Failed valve control solenoid · moderate

Information, not instruction
CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.
Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

What makes one worth reading:
- The car — make, model, year and engine. The same fault behaves differently on each.
- What you measured, not only what you replaced.
- What actually fixed it — or that nothing did, which is worth knowing too.
