Volvo D12 Boost Sensor Replace Results


RandyA

Recommended Posts

I've put a little over 700 miles on the Volvo since replacing the boost/temperature sensor. On my truck, I can feel a noticeable improvement in engine responsiveness and overall performance.

 

Not sure about fuel mileage due to the differing terrain we have covered (10% grades, flats, hills) but it is looking like I may have picked up anywhere from .5 to .8 mpg. Either way, I would be happy.

 

My old sensor was possibly the one that came in it 796,000 miles ago. It was time for a new one. It is looking like it was a worthwhile expense for my engine. Please don't think just because I am seeing improvements others will experience the same. Your results may differ. OTR Performance advertisements say replacement after 250K is needed.

Randy when I replaced my sensor this summer I saw a real improvement in performance because my turbo would not work at all and there are some pretty big hills out here in the west that I was limping up. It is hard to tell about the mileage average because of the hills and twisty roads out here but I'm back to the 8s range and I was down in the low 6's without any turbo. I'll know better when I get back to flat lands in Oct.

 

When I replaced mine I had also watched the video you mentioned early on in your installation. The install was not hard to do (2 plastic panels, 3 zip ties and a total of 7 - 9 screws). It took me about 45 minutes. It would have taken me longer to use your shortcut and I would have worried about my soldering abilities. Just goes to show that there is more than one way to do the job and it depends on the your skills (mine is not soldering).

Glad to hear you have improvement. Sure is nice to have the turbo back isn't it?

This is easy Phil. Glad I could be of assistance.

Let us know if there is any other advice we can give you.

  1. Headlights Don't drive at night and you don't need to do this at all.
  2. Boost sensor If this needs replacing it is top of the list because it affects performance. If it is not acting up save the part for when it starts acting up.
  3. re-upholster the seats Seat covers and call it good
  4. sand all the plastic chrome on the front and cover it with black bed liner material If you have time for this you are not working enough hours
  5. polish the rims Hire a teenager.
  6. replace cab floor mat - should be here Monday
  7. tires for the rear axle - done

P.S. RandyA

Pardon my poor manners on the hi-jack, I could not resist

E.P..

Pardon is given. I enjoyed the banter..... especially when Phil is the one being poked :P .

 

Brad - thanks for adding your experience with the boost sensor. The main reason I elected not to follow the OTR video is every time I begin to remove a bolt or screw there is always at least one that won't come out/loose and I end up breaking it off and spending even more time fixing what I never planned on fixing. Murphy's Law, you know.

Randy I understand perfectly. Mr. Murphy seems to have a seat somewhere in my rig and I can't find it. He shows up at the worst times.

 

And I also like poking at Phil. By the time I go thru Houston again he will have forgotten.

I've heard that you can get away with things if you buy the deputy lunch and a Dr. Pepper.

Does League City count as Houston? Expect to be there late this winter.

 

How much Dr Pepper should we bring to ensure a pleasant, hassle free experience?

Okay, since this thread is already beyond hijacking.....

 

If I went to the Dr. Pepper distributor and loaded all I could cram on board with the intent of having it ready as a bribe if hassled by T-DOT, would I be commercial. :ph34r:

I've heard that some people are attaching counter-measure launchers to their rigs, throwing out several simultaneously, like chaff, hoping to swamp the DOT guy with multiple targets at once in an effort to sneak away.

Un-hijacked - Richmond, VA to Goshen, IN. Interstate, mountains, stop lights, stop and go traffic, 70 mph on open highways. This did not happen before replacing the boost sensor.
