RandyA Posted March 19, 2015 Report Share Posted March 19, 2015 Ran across a You Tube video on replacing the turbo boost sensor on a Volvo D12. OTR Performance seems to believe that this sensor only has a lifespan of 200K miles. They show the sensor as a buck fifty, don't know what Volvo's price is. But "IF" this sensor is subject to degradation I think I will pop a new one into my D12, Does anyone have any first hand factual info that has replaced this sensor that they would be willing to share. I mean if replacement is hype I won't bother, but if it is true I will.

sclord2002 Posted March 19, 2015 Report Share Posted March 19, 2015 Randy, I have been considering the OTR egr delete kit in the event I start getting EGR valve codes. OTR recommends replacing the boost sensor when the EGR delete kit is installed. It seems that there should be some kind of test for the correct output from this sensor, but, who knows ? I would love to get better fuel economy but am hesitant to let go of $150.00 just to see if it works......but I think you should do it as a service to your fellow Volvo owners. We would all be most appreciative. Heck, if there are 150 Volvo owners here, each of us could just send you a buck to cover the cost of the sensor. If you will come to the ECR, I'll have my buck ready for you. Carl....how about you ?? Charlie Don't ever tell a soldier that he doesn't understand the cost of war.

dascom Posted March 19, 2015 Report Share Posted March 19, 2015 Should you not be able to look at the sensor levels in normal operation? If the readings are good, I wouldn't spend the bucks. I found this software for checking things like that but haven't looked into cost or useability. http://www.volvoways.com/Pttsoft.html Yamaha V-Star2007 Kenworth T2000 tandem aircutterThermoKing TriPack2003 Holiday Rambler 36' Presidentialshort trips-88 Allegro on Astro Link to comment Share on other sites More sharing options...
Nuke-E Posted March 19, 2015 Report Share Posted March 19, 2015 While I don't have the same engine, I did replace several sensors a few weeks ago. I went after the Intake Manifold Absolute Pressure (which reads turbo boost) and Exhaust Gas Pressure. Both sensors were less than $50 each, and a quick turn of the wrench to replace. I also at the same time cleaned the intake air temperature sensor (which I do somewhat regularly). I've only driven ~600 miles since the replacement, and don't have a feel yet for the mileage impact. The first 150 miles had a lot of traffic lights (probably about 100, exactly 1 that I passed through without stopping), and the other 450 was into a strong headwind, freezing rain, and snow. What I can say is that it's much more responsive. I think all 3 sensors would read accurately enough steady state, but the layer of crud was slowing any movement of the diaphragms on the pressure sensors, and the soot was acting as a thermal insulator on the temperature sensor.

I found this software for checking things like that but haven't looked into cost or useability. http://www.volvoways.com/Pttsoft.html The catch 22 here is having either a Vocom, 88890020 or Nexiq interface. And, in some cases access to the Master Volvo Server to obtain your trucks original firmware by VIN number. No doubt an owner of such a tool could could recoupe some of the interface cost by bringing such a tool to a HDT rally. Charlie - I will accept a $1 from everyone interested that wants me to buy the sensor with open arms but I strongly suspect that my PayPal account or mail box will not overflow anytime soon. . What I DID note on the Volvoways website was a service using the interface and software that links to their server and deletes the EGR function and resultant codes and even another program that deletes the DPF/DEF requirement on newer engines. I am sure both are illegal for highway use but there was no disclaimer.... or cost shared. The legality of the reprogramming leads me to believe getting a Volvo shop with the Vocom, 88890020 or Nexiq interface to perform the service in concert with Volvoways might not be possible. I doubt that a Volvo shop would risk knowingly taking that step. So, it looks like buying a used Vocom, 88890020 or Nexiq interface could be in your future?

dascom Posted March 20, 2015 Report Share Posted March 20, 2015 Randy, to further hijack your thread: I have been searching for ways to bring my truck data out to make it useable with my pc. Of course when I get that done, will still need to map the information into some understandable format like gauges, charts, and indicators. Have been thinking I might stream the info into MatLab to fill up and update data locations, then use those values to drive software indicators. Most of the things I have found are pricey and that shouldn't be. It's just data. Here is the physical layer stuff I have located. http://www.dgtech.com/product/dpa/manual/DPA_Pinouts_Dec2012.pdf And the message format http://www.intrepidcs.com/technologies/j1939.html also some history and what my cat motor ECM records, or can record. Electronic Engine ControlsThe manufacturers of all diesel engines for commercial vehicles use electronic controls for thepressurization of the fuel, injection of the fuel and timing. First introduced in the mid 1980’s on bussesand fire trucks, these controls became standard on all heavy-duty engines between 1991 and 1994.Medium duty engines became standard with these electronic controls in 1998. Both applications weredone as a means of meeting more stringent Environmental Protection Agency (EPA) limits for emissions.Once these electronic controls took hold, engine manufacturers looked for additional uses of thecomputer. Over time, the controls took on additional inputs and outputs, control of power take-offoperation, transmissions, and other ancillary controls. The processing power of these computers startedwith simple 8-bit microcontrollers and has now reached the power of 32-bit processors. Memory internalto the units has grown and the type has changed. It is now common to find nearly a megabyte of memorywith most of it of a non-volatile type with some of it readable/writeable for storing information. Thephysical size of the computer has grown somewhat, with connector pin-counts starting at around 30 andgrowing to over 140 in some controls today.The Caterpillar engine control is the most full featured, at least as far as pins on the connector andstorage of information. This engine control stores such items as those shown in Table 2:CaterpillarEngineControlData RecordedState Line Crossing Driver ID Instantaneous FuelEconomyAverage Fuel Economy Fuel Used Trip LengthTrip Time Trip Average Speed Vehicle SpeedCruise Set Speed Instantaneous Fuel Rate Engine Load PercentEngine RPM PTO Set RPM Fuel TemperatureBoost Pressure Coolant Temperature Oil PressureCold Mode on/off Multi Torque on/off Intake ManifoldTemperatureAmbient AirTemperatureHigh Coolant Temperature Warning Very High CoolantTemperature WarningLow Oil PressureWarningVery Low Oil Pressure Warning Low Coolant LevelVery Low Coolant Level High Intake Air TemperatureWarningVery High Intake AirTemperature WarningLow Voltage Vehicle Overspeed Engine OverspeedLifetime Totals foraverage fuel economy,distance, average speed,fuel used, time, PTOfuel, PTO time, idle fuel,idle time, percent idletimeLeg Totals for average fueleconomy, distance, average speed,fuel used, time, PTO fuel, PTOtime, idle fuel, idle time and percentidle timeTrip Totals for averagefuel economy, distance,average speed, fuel used,time, PTO fuel, PTOtime, idle fuel, idle timeand percent idle timeNext PreventativeMaintenanceLast Preventative Maintenance PreventativeMaintenance OverdueEngine Fault Codes Hard Braking WarningTable 2: Caterpillar Engine Control Has Extensive Information Stored in It.

sclord2002 Posted March 20, 2015 Report Share Posted March 20, 2015 Randy, look in the "West coast rally in Sparks nv" thread for LOU10, post #55. He has tons of software and diagnostic equipment and has offered to hook up to trucks at that rally. We should be able to contribute to his plane fare if he would be willing to come to the ECR......or a truckload of Pepsi if he wanted that. My Volvo shop would not even disable some of the shutdowns on my truck. Charlie Don't ever tell a soldier that he doesn't understand the cost of war.

I have kept on looking at ways to get into the data bus and think this might be a $30 way to bring that flow to the laptop, tell me what you think. http://elmelectronics.com/DSheets/ELM327DS.pdf I like what I saw but would need more time to digest and research the project further before seriously considering jumping into a build. These things look simple in schematic form but can add up to a whole lot of unanticipated money spent by the time it is completed and working. I built an interface for the 1988 non-OBD2 GM data stream to a standard RS232 bus with a simple BASIC program to decode the data into readable scan lines back in '96. So, this is not a new idea for me. But, while having a "Scan Tool" for the J1932 bus would be nice, many of the scan functions are already available in the Volvo VN DID. What I would really like to have is a tool to modify the user parameters in the EECM that are doable without going through the Volvo server. BTW - there is some "interesting" stuff coming out of China that ranges from $120 to $350. Check the link to this one but be aware it may expire soon and become a dead link. Considering all the cables, etc. included the price is OK. Of course you never know if it will actually work or not. That is where the Ebay purchaser guarantee is a nice feature. Actually, I have bought a number of electronic assemblies from China and have had zero failures. They are well cloned from OEM products. Nothing further on the boost sensor until we get back to home ground in April. I will pull mine out once the truck is not needed to get us home, give it an eyeball and make a decision on to replace or not.
