I have a 1998 V70XC with 90k miles. I recently failed my inspection due to check engine light. The code is P0107. When I looked it up via the diagnostic codes website it indicated "MAP/Baro circuit low input". So question 1, is there a MAP sensor on this vehicle?; 2. if the car is running fine does it need to be replaced?; 3. Are there any other options?; 4. if we get the check engine light to turn off will it still trip this code?

The next issue is my right front wheel bearing. Yes, I'm getting a nice hum and vibration in the steering particularly at speeds over 70. Funny that it stops when turning the wheel left. I want to confirm that the wheel bearing should be replaced. I recall seeing a post that replacing it didn't fix the problem?!

Is there anything else that should be done or looked at here? i.e. wheel hub, boots, etc.? Any advice would be greatly appreciated!!

THANKS!

 

not sure about dtc.

with regard to the wheel bearing, if it goes away when turning this is indicative of a wheel bearing. i would first jack up that side and see if there is any play in the wheel. if it is in fact a wheel bearing, get it replaced. wheel bearing failures can be extremely dangerous. the nice thing is that there is a warning period, which you may be in right now.

 

The Baro sensor should be located on a bracket right next to the Hood latch on the right side of the car.
Like right infront of the washer fluid fill.

Sounds like the Bearing needs replacement.
