Disconnect the battery negative cable for 1 min 30 seconds. If it comes back on, a local parts chain store will read your code for free in hopes of selling you the part for the repair.

Need to know what this code is for 2003 toyota corolla -p1349vvt.oil light and check engine comes on.

you are having a problem with the variable valve timing system which depends on oil pressure to move an actuator which changes the valve timing. this could be because the actuator is clogged or your engine oil pressure is too low. Check the engine oil level first. If the engine has the proper amount of oil, you will need to have the oil pump pressure checked. If that is good, then the variable valve timing actuator should be checked for clogging.
