VSC, VSC OFF, Check Engine - code P1653 - Toyota Nation Forum : Toyota Car and Truck Forums

bufi · 10-19-2006, 12:08 PM

For the last 9 months I've been struggling with the Check Engine, VSC OFF and VSC indicators. Every time i visit a dealer, they just clear the check saying that this shouldn't happen again. It does, sometimes after a week or month, sometimes on the same day. This doesn't seem to affect the driving.

They seem to have no idea what to do with the car, so I asked about the codes. They mentioned P04** (dont remember exactly) and most often - P1653.

Any tips?

I have Toyota Avensis, 2001 T22 model.
Sorry for my english,

Bufi

I have a 2003 xls and have been having the same problem. Check engine and VSC Off is displayed for several days/weeks and then it mysteriously clears itself. It was ok for about 4 weeks and it's come back again. I haven't taken it to the dealer yet.

I'll ask for the other codes today.

I have the VSC ON/OFF button, and it works as long as the indicators go off at the same time. I'll have it checked today.

For the last five days the lights cleared and came back at least once a day. Usually clear in the morning, and back after driving about 20km.

P1653 is definetely the VVT-i system problem, but what can be wrong about it?

Hi,
I am having similar problems regarding Engine,VSC and VSC OFF lights, with Avensis 2 litre VVTi Auto, this has related intermittent problems with the gear box not moving from Direct to Overdrive.
Changed gearbox oil and one of the four oxygen sensors (another errror code) lights still come on.
Any further suggestions,
Have not looked at OCV yet.

csaxon was right, I had some VVT-I sensor replaced. VSC AND VSC were cleared and never came back. But the Check Engine did...

The winner code is P0420. Diagnosis: cat system. Solution: replace the cat.

This is freaking me out. The new cat is 800Euro here and I checked the emissions - everything perfect. Any other ideas?

CSaxon,

Read with interest your threads with Buffi, could you suggest any reason why this code P1653 should affect the gear box of an Automatic Avensis, 2000cc VVTi.
The engine light, VSC and VSC OFF come on intermittently and for example tonight the lights are on but the gearbox is working normally !!, the lights come on with slight Accelerator pressure and could stay on for sometime.

CSaxon,

I will try and explain more clearly. This is difficult as I have had all combinations.
The problem first occurred some months ago.
Very randomly, would not go into O/D (It has never gone the other way - while in motion !!)whether the E,VSC,VSC/OFF were off or on.
Toyota garage came up with P1653 and both them and Toyota did not have an answer. They changed the transmission fluid but this did not clear the fault.
Because of it being an Automatic I took it to a Tranmissions expert .
He came up with an error message indicating one of the oxygen sensors was faulty, this has been changed. Within days the lights came back on, whether the gearbox was operating normally or not.
Last evening drove 10 miles, normal transmission operation no lights came on,(I could manually switch O/D button on/off and do the same with the VSC Off button.)
Accelerated from roundabout and could not get out of Direct drive. Temperature gauge showed normal.
I do not want to throw in a "red herring" but there has been less showing of the lights since the Oxygen Sensor was changed.
You mention in an earlier post to Bufi that his OCV may be faulty, could you tell me where this and the associated filter are under the bonnet.

Regards,

Allan45

CSaxon,

Thankyou for the information / drawings.
I am sure I will find the OCV from this.
Just to show how intermittent this fault is :-
Today, again the car was normal until it heated up, put foot on the accelerator, then the lights came on and it would not go into O/D.
The lights remained on all day, the car was started say 6/7 times but never started from cold. During the day sometime the O/D would work and sometimes not..The whole day was town driving, UK style !!

I will look into the OCV as soon as possible and post another reply, Thankyou.

Sorry for my misunderstading, thought Avalon was your eqivalent of the Avensis, similar name.

Regards,

Allan45.

CSaxon,

Had the OCV cleaned on Friday, checked the sensor for corrosion at the same time.

No corrosion evident on the plug.

Cleaned OCV with petrol and blew it out with air line, no obvious blockage.

I have waited until now to send this note as you know the problem has been very intermittent, but since Friday NO LIGHTS and NORMAL GEAR CHANGING.

If I am being too hasty and the fault has not gone I will post again after I have changed the OCV.

For your info the UK cost of an OCV has reduced from approx. £200 to £50 in the last couple of years, so changing it would not be too expensive.

I hope you do not see another post from me on this topic but I would like to thank you for all the information and time you have afforded to me.

Thankyou

CSaxon,
Sorry still a problem.
Last evening (Monday)
As soon as I joined the motorway, engine hot, lights came on and transmission would not go into OD!! On the return journey after standing for 2/3 hours , lights came on when switching on ignition and stayed on for the remainder of the journey (45 miles) still would not engage OD. This morning lights came on with ignition and have not gone off all day (very short trips).Cannot confirm if transmission working correctlty.

I have ordered an OCV, but I am wondering about a possible link to temperature. What may not work correctly at high temperature (normal driving temperature ) stopping the move into OD. ? Does some equipment other than that you have already mentioned measure / send signals regarding temperature, viscosity or pressure etc. ?

You showed on the drawing the OCV pushing the oil in different directions when in HOT and alternatively Cold conditions. What operates the OCV ? - A solenoid ? -from a thermostat ? - from a sensor ? - a relay ?

Sorry if I appear to be impatient but this has gone on for nearly 4 months.

Regards,

Allan45

CSaxon,

The new OCV did not fix the problem.

I have officially approached Toyota UK but have not had any answers.

There is no Haynes Manual on the Avensis until possibly February 2007 so to find the locations of sensors I am having to go back to the Toyota garage.

I posted this in case you thought I had got lost.

Happy New Year,

Spoke with Toyota UK the day of your last posting and after chasing have received the following reply :-

''The error code P1653 is a generic On Board Diagnosis (OBD) code as identified by Bosch which relates to an oil level lamp central circuit. The Avensis does not have an oil level lamp and therefore it is safe to assume that if your vehicle is running correctly in every other respect then this is nothing to worry about.''

As we know the vehicle is not running correctly and if they had read the e-mail they would know as well. I have re-sent my e-mail and will keep you up dated with any diagnosis.

Regards,

Allan45

Took my '03 XLS to the dealer and got it fixed. They said it could be the sensor or charcol canister or rust on the gas fill pipe. It turned out to be a rusting fill pipe. They replaced the fill and check engine, vsc off lites went out. They said the vsc/trac lites always come on whenever the check engine lite comes on even if vsc is ok.

Mr. Manuel Pou · 02-05-2007, 12:18 PM

Hi Allan45

I also have an avansis and have had all sorts of problems with the lights coming on on the dash.

I have taken the car to the dealer about 10 times and each time they can not sort the problem. Please keep me updated as I am getting very frustrated.

I seem to loose top gear too, do you have this symptom?

Here's Hoping..

Manuel

hi!!

(sorry for my english)

I'm really happy to see some forum, and to read about the same trouble I have.
I've got Avensis 2001, VVT-i, 2.0l
Still VSC OFF, VSC and E lamps are on. Computer says: 1653. What should I do?? What does it mean, nearly I know from you this forum. But tell me, please, clear how to fix this three things??
Important thing is my car goes without any troubles with speed, temperature etc. His fast, strong, so I do not have any breakes in accelerate.
