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 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

If you are not experiencing any actual driveability problems such as with your brakes, considering the DTC P1653 with P0650 then the problem may be electrical.

Start your search with the fuse for your traction control system, it is under the hood in the compartment mounted to the passenger side strut tower. If nothing is wrong with that then check your wiring harnesses from that box for loose connection or wire damage, and also under the dash.

SOURCE: how can I maintain a 1AZ Toyota engine to last

I have a Corolla which we call "old faithful". It has never missed a beat except twice when we had to replace the battery.
During this time I have had an Isuzu which doesn't run anymore, a CAM (Chinese pick up) which I sold, thank goodness, and I presently have a Mahindra Scorpio truck, but old faithful will never be sold. I have pledged it to my grandson for when he gets his drivers license.
Frankly, we don't touch the engine. Every 20 000 km I replace the filters, drain and replace the oil and the spark plugs and that's it, unless I forget and just let it run another 20 000 km.

My Toyota Voxy 1998 engine 1AZ FSE won't start, no spark from spark plugs..What is causing this?

Hey Rosalina, There are several reasons it won't spark. No need to go into all of them here...This needs to be diagnosed by a professional..( I know they are $$$) but in the long run you won't be just guessing, and replacing parts, .. and hoping it works, this method is usually more $$$$

What is the meaning of p1653 scv motor circuit fault code on toyota rav4 1az 2001 engine

P1653 SCV Circuit Malfunction
This could be caused by the oil control valve, low oil level, infrequent oil changes, a fault in the wiring to the valve or a bad PCM. What is odd is that the code is not listed in my information database.
