Question

Can you please explain the OBDII Code P1354 appearing in a 2001 Toyota Highlander. Replaced all coils one year ago. Then replaced coil #4 two weeks ago but car still shudders as if trying to stall and then this code appears. Car has oil changes on time and throttle body cleaned. Please help.

HI there

This code is for a variable valve timing malfunction on bank 2.

There can be several causes for this code, low or dirty oil are the simple and most common issues. You can also have a probem with the VVT solenoid which would be an electrical issue or an actual mechanical problem with the timing.
