TPS Can Be Adjusted...It Have Its Ways Of Checking Which You Can Know If You Have Service Manual..
Kindly LOOK For Its Service Manual.....And It Will Have Its Procedures And Readings Mentioned
I Know TOYOTA Readings But Not Sure About Suzuki....
The Error Code Is Of Bad IAT But A Good Working IAT Still Can't Get The CODE Sorted...This Is Strange....
I Would Suggest To Replace It With Other Same Model Car Both Sensor And Later ECU.....You Will Know It
And HUNT For Its Service Manual......
If The CODE Is Not Bothering You Performance Economy Wise....Let It Be There For A Time
