SOURCE: My 1az fse engine running roughly, and cylinder 3 and four got sparks but not functioning
have a compression test done as it may be a blown head gasket between those two cylinders.
first you have to run the fault codes to find which sensor turned on the limp home mode so that you do not waste money chasing maybe's
engine lights do not only refere to the engine but to the transmission as well so unless you run the codes it may well be in the transmission
on one of the forum ages code p 1653 refers to SC V motor circuit
toyota recommended the change of both vacuum valve assembly parts T25860, -OHO30 and T25860-28070
the c person asking the question replaced the units and to date the problem was fixed
go google and type in --toyotanation.com as this is a forum page and most replies state that it is a vacuun valve assembly problem
one person had this to say the following malfunctions were experienced
VCS, VCSoff and engine check light on
the gear is alternately was stuck on overdrive --stay at the 3rd gear ( the od light not on)
the computer code reported a p1653 malfunction code
after replacing the vacuum valve assembly the symptoms went and haven't come back
any way go google and type in-- fault code p 1653 for toyota --and search pages to get a better understanding of what is wrong
