OBD-II Code
P1349
Severity
Not yet reviewed
Nobody on our side has assessed this code yet, so we are not going to guess at how serious it is.
Can you drive it
We cannot say
Treat it as unknown until a shop reads it with live data. If the check-engine light is FLASHING, stop driving as soon as it is safe to — that means an active misfire, whatever the code.

From this code's diagnostic notes. Varies by vehicle, diagnosis, parts, and local labor. This is not a repair quote.
P1349 is a Toyota VVT-i system malfunction set when the ECM commands the intake cam to advance or retard and the actual cam position (read from the camshaft position sensor) does not match the commanded position within a calibrated window, typically more than 5 to 10 crank degrees of error sustained for several seconds.
How a shop works this
Work from evidence to part, not the other way round. A code names a circuit or a symptom; it does not name the part that failed.
Note every code that is set, not just this one.
Codes that appear together usually narrow the cause faster than any one of them read alone.
Read the freeze frame — the conditions the fault was recorded under.
Cold or warm, idle or load, road speed and engine speed. A fault that only appears cold is a different fault from one that only appears under load, even with the same code on the scanner.
Confirm the fault is current rather than history.
Clear the code and see whether it returns under those same conditions. A code that does not come back may have been logged during a repair, a flat battery, or a bad connection that has since been disturbed.
Then follow the diagnostic notes further down this page, in the order they are written.
They are written in the order a shop works this code, cheapest checks first. Where they name a component, inspect its wiring and connector before replacing it.
If the code comes back after a repair, the underlying fault is still there. That is the point to bring in a scanner with live data and freeze-frame, or a shop that has one.

P1349 is a Toyota VVT-i system malfunction set when the ECM commands the intake cam to advance or retard and the actual cam position (read from the camshaft position sensor) does not match the commanded position within a calibrated window, typically more than 5 to 10 crank degrees of error sustained for several seconds. The system uses an Oil Control Valve (OCV) that meters engine oil to the cam phaser; when the OCV screen plugs with sludge or the phaser locking pin fails, the cam either won't move or moves erratically.
Cheapest-first ladder
- change the oil and filter first if it's overdue, then remove the OCV (one bolt on the front of the head on 1MZ/2AZ/2GR), inspect the inline screen for varnish and metal flake, and clean with brake cleaner.
- Bench-test the OCV with 12V across the terminals; the spool should snap audibly and freely.
- Live data: monitor VVT Target Angle vs VVT Actual Angle in Techstream during a 1500 rpm hold; deviation under 3 degrees is healthy, sustained deviation over 5 degrees confirms the fault.
- The expensive misdiagnosis is replacing the cam phaser ($400 to $900 in parts plus 6 to 10 hours labor) when the real fault was a $12 OCV screen clogged from a missed oil change, or a $90 OCV solenoid that bench-tests bad.

Toyota 1MZ-FE and 3MZ-FE V6 (Camry, Avalon, Sienna, Highlander, RX300/330 1999-2007) is the original P1349 platform, with TSB EG053-08 directing technicians to inspect and clean the OCV filter screen before condemning the phaser. Toyota 2AZ-FE 2.4L (Camry, RAV4, Solara, Scion tC 2002-2009) is notorious for OCV screen clog driven by the engine's well-known oil consumption problem. Toyota 2GR-FE 3.5L V6 (Camry, Avalon, Sienna, Venza 2007-2014) typically throws P1349 from a stuck OCV solenoid rather than screen clog. Toyota 2ZR-FE 1.8L (Corolla, Matrix 2009-2018) sets P1349 most often from a worn intake cam phaser internal locking mechanism that rattles on cold start.
Estimated repair$40 to $1,200.
