Code p1349 in toyota echo 2004 - 2004 Toyota ECHO

Under certain conditions customers may experience a MIL "ON" condition with DTC P1349 indicating a variable valve timing (VVTi) malfunction. In some cases, the cause of this DTC may be the VVTi actuator.

In general P1349 is a misfire or ignition issue under most general OBD-II - but Toyota spec'd OBD-II has it as a VVT malfunction. Unfortunantly - hard to tell which it is. Might be the ignition timing set too advanced (VVT-i issue) or low fuel pressure (bad or clogged injector, bad or low flowing fuel pump/regulator). An emissions test could tell you which one it is. If you want to try a quick fix on your own, I'd start with the basics, change the spark plugs, air filter, and maybe the pcv valve, all these are cheap and easy. Other things could cause the problem though, so if the quick fixes don't work, I'd lean toward the injectors.

Seafoam and other additives are very good solvents that can help clean the injectors - but may not be strong enough to clean off these injectors. Injector cleaning services generally don't work that well - best way is to have these cleaned ultrasonically or replaced (very costly).
