Codes DON'T tell you what to replace

Study OBD2 Systems

You just had a sensor reporting an out
of range condition

You then have to diagnose the reason

Have a professional take over

Toyota sienna 2008 check engine light , with code p0352, is on as well as the VSC and trac off . What is wrong?


Find out what the sensor the code is refering to and rep[lace it for starters. The engine light is only telling you that there a fault has been found in the paramaters for sensors that have been set in the cpu. Buy replacing the faulty sensor as shown by the fault code you may also eliminate the other faults as well

2007 Toyota sienna V6 P2197 code from Autozone diagnostic.


Solved. I have 2008 Sienna with Check Engine and VSC lights on. Scanned codes were P0051 and P2197. Oxygen Sensor Bank 2 Sensor 1 needs to be replaced. You can see this sensor on the right side of the engine when you open up the hood. You need to get an Oxygen Sensor socket (I used Tekton 7/8in 22mm which costs $9) and a wrench extension to reach it. Spraying liquid wrench a few times on the base of the old sensor also helped to loose it. The replacement sensor I used was Denso 234-9049 which costs $85 from eBay. Lights went off after the sensor was replaced. It took me 30 minutes to replace.

My 2001 TOYOTA SIENNA XLE is showing a P0420 code Problem? My Check engine light is on, My Traction Control light is now showing off? and my VSC(Vehicle Stability Control) Light is on too? After...


Exhaust Converter-- (PO 420) -- may be melted inside and restricted

That causes the O2 Codes

You will need to find out why it failed ,and correct,
or it will fail again

You will need to replace all the O2 Sensors, also

The Traction,VSC and so on, are other problems,that have to be
diagnosed

2004 toyota sienna engine and vsc light


well the check engine light on can mean many different issues its just a symbol telling you that your ecu (engine computer) has found an issue with your vehicle it is not a specific indicator of whats going on unless you get the codes pulled from your computer any autozone will pull the codes for free and some shops will also just call around they will not diagnose prob for free though it could be anything vacume leaks - o2 sensor bad ext....as far as your vsc being on most of the time when your check engine light comes on the vsc will light up also does not mean there is an issue with your vsc system....i work as a mechanic for a toyota dealer and see his all the time and check to make sure your gas cap is tight will set check eng and i see it all the time when custs forget to tighhten gas cap if its loose you can get the codes erased hope this helps!!!!
