Because of our time difference, can you please give me any other thing you think I should sort out tomorrow. Also I have read that the TPS should always be in the middle position. Is this correct please?

TPS does not necessarily mean it should be at center, it is there or abouts but only checking the voltage can you be sure.

You need to get the O2 sensors going so the schematics should be enough for you to get on for the time being.

Hello Low, am done with my o2 sensors I think cos they havent showed up again, now my VSC(OFF) light has been on for ages, I want to get that corrected, I sent car for diagnosis and mechanic says its my Front Right Wheel Speed Sensor and also says I need to change my Engine Coolant Temperature Switch. Please advise. Thanks for all the help.

There should be trouble codes, let me know what they say.

I dont see any trouble codes, my Check engine light is off, the only lights on now are the VSC OFF and the auto leveling for the headlights. Thank you

VSC light can be turned off or on by the switch. Does it work?

Why does the mechanic mention a faulty wheel sensor when you don't have trouble codes?

You would need appropriate scan tool to check the headlight levelling and it dould be due to a blown fuse etc. There are not much information in our database regarding this, only the wiring schematic is available.

Please send me wiring schematics so I can let my mechanic check. Thanks for all the help. I really do appreciate it

Here they are. If you print them, they should be better than the PDF files.
