P1349 — Variable Valve Timing (VVT) System Malfunction (Bank 1)
CAUTIONIs it safe to drive? Drive gently and get it looked at soon — it can worsen or fail inspection.
What P1349 means
This is a manufacturer-specific code — its meaning depends on the vehicle’s make (see below).
What P1349 means on specific makes
Toyota / Lexus / Scion CAUTION
The ECM commanded a cam-timing change via the oil control valve but the camshaft didn't reach the target angle. The VVT actuator/oil control valve uses oil pressure to advance or retard the intake cam; this code means that loop failed.
- Stuck/clogged VVT oil control valve (OCV) ($60-200)
- Low/dirty oil restricting flow
- Failed VVT actuator (cam gear)
- Sludge in oil passages
Check first: Fresh oil and a clean/working OCV fix most cases; test the OCV's resistance and that it spools oil. Pairs with P1346 and misfire codes.
