My 2001 Volvo xc70 keeps getting the engine system service required light coming on intermediate.Had codes pulled and got these codes.9150 TB sensor 01 fault.902a throttle unit communication .And 9400 faulty brake pedal position sensor.just replaced pedal sensor yesterday.service light went out for a day,now it's back.Does the throttle body codes mean i need a throttle body.still has original white sticker body.I ordered a TB from xemodex tonight but I'm not sure
Any thoughts on what it may be?

 

no idea regarding those things here, i would say that it could be resolved at the desk support for any further queries
