Hi guys. Any idea what would cause faulty signals to these sensors?

My VSC light is on but its not going into limp home mode. A backstreet garage plugged their computer into it, despite telling me what faults their machine came up with, they advised i take it to Lexus for a proper diagnosis as they were having problems connecting to the ecu.

MAF sensor can be cleaned easily if its not been damaged. I was quoted £100 for used one on eBay. I didn't look hard so I am sure you'd find a cheaper one easily if the MAF was damaged. MAP sensor, I'd think it might be the same price but I don't know much about it. In any case, I would recommend you and everyone to buy a cheap code reader that works with the IS. Do you have any Lexus warranty on the car, if so go to Lexus first.

No, I've not got Lexus warranty. However I've only had the car a couple of weeks & It's still under warranty from the used car dealership.

My car is booked into Lexus Edinburgh next Wednesday & I'm glad I am not having to pay at £95 an hour Labour.
