Default P1349 Code

Thought I would share my experience with the P1349 code which is Variable Valve Timing (VVT) system malfunction on Bank 1. The fix for this can be several things. Cleared code several times and it would always come back after engine got to operating temp. Getting to the screen to clean is difficult so did not start there. Removed the solenoid valve and checked. Oil looked very clean and did not see any varnish which would lead to sticking. Put 12v on and even pulsed it and seemed to work perfect and coil measured 104 ohms exactly like new one. Everything with valve checked out perfect. Put new one in and fixed the problem. Bench testing does not really test this under real conditions like hot and maybe fast pulses. If this didn't work I was going to do the techstream test. Just goes to show that even though it checks fine it can still be bad.

Curious as to how many miles were on your car when the code was set?

One of the keys to keeping the oil control valve and VVTI gears healthy is frequent oil changes with good oil. Once more reason to stick to the 6 months/5,000 mile schedule in my book.
