2000 Volvo 770, 700k miles.
Converted to RV hauler.
I get a warning light on dash and code "Turbo Data Erratic".
I also feel a slight loss of power going up hill.
AND jake brake won't work when the warning light comes on (erratic).
I'm hoping it is a simple as the turbo sensor.
What do you think?
Looks to be on back of intake, maybe a little challenging for me to get to?
