I need help or info on DTC`s,
My engine managment light comes on after a few minutes of driving. i put our toyota tester on it to check codes,
I got two codes: P0500, Vehicle Speed Sensor Malfunction
P1656, OCV Circuit (Bank 1)
Im not too worried yet about the speed sensor, as all clocks are working.
The OCV sensor relates to VVT sensors, but i cant dig up anything in the manuals on this as it has Dual VVT-I. i have checked restance in both sensors and are the same, about 8.8ohms, i think. has anyone seeen these problems or know of anywhere i can get repair manuals for the altezza? i have tried downloading the file on altezza repair manuals that is posted on the forum, but no joy...
Any help at all will be greatly appreciated,
Thanks in advance,
