Does code p1349 mean I need to change the timing chain on my 2001 Toyota Echo?

Question

I had a computer scan done and Codes P0301, P1349, AND P1790 CAME UP. What do I need to do?

Answer 1

P1349 VVT (varaible valve timing) System malfunction

P0301 Misfire number 1 cylinder

P1790 Shift solenoid valve ST circuit malfunction

P1349 can be blockage of the OCV (oil control valve) , and this  would be a hopeful condition, What causes P1349 is the VVT actuator which can cause rough running condition and even stalling. You will not need a timing chain but just the VVT actuator, As for P1790 this is the Shift solenoid ST valve, this solenoid just replace it .
