Vp44 death symptoms

Posted

What are he symptoms of a dying Vp44? Current one has 15 k on it the P.O. put it on a while ago in 2014 I think... as you know I have been having power issues but now it’s been fine lately. Not gonna be surprised if it comes back though. This was my next concern with the power issue. Is there  a way to test the pump?

codes and running issues.  

 

I doubt your issues are with the vp44 though,   everything you have posted screams electrical issue.

Pay the $1,200 and replace it. 

 

The sad part is the pure cost of becoming a Bosch Certified Rebuilder plus the cost of buying the Bosch 815 test stand. Then every pump takes about 3 hours to run its course on the test stand. Even if you had a way to send back a pump they are not going to test for free. It will be a pretty penny being you are taking away from there profits.

White smoke, low power, no start, and there is a list of error codes.

The best thing I can suggest is to get a OBDII tool that does live data and monitor all the data you can to see if there is a certain condition that is tripping this off. Sensors do fail within specs and behave weird which might cause issues but never throw a code because the data given is still valid. Some things you might be able to spot right off like temperatures coolant and IAT should match at start up then the coolant should be in the 190-195 realm. IAT is a weird animal be it should be about +40*F over outside temperature at full coolant temperature. MAP sensor is a bit troublesome to diagnose but the sensor is quite expensive. Tach signal should be smooth. APPS sensor is another weird one that might fail within specs and do weird things too. Typically you can spot these with DVM or live data tool. There will be a sudden drop or rise in signal voltage.

Any advice on a obd11 that doesn"t cost arm and leg but does job for average guy?

Is $49 bucks too steep for your blood? This is the same tool I'm running...

Look up elm327 on Amazon. The Bluetooth ones work with any android device. Its the ****. I got the torque pro app for like 5 bucks and the adapter for like 25 bucks. There are also other apps. Less than 30 bucks invested and tons of possibility. Plug it in and leave it, no need for devices to stow in your glove box.

That might be true. However, I bought the cheapest one I could find on eBay about 5 years ago. Still works. Reads and clears codes, can get live sensor data, etc. Not the fastest thing in the world, but works. The guts of the brand name and cheap ones are likely very similar if not the same. Brand name and warranty tend to cost a lot more. Depends on if those things are important to you. I'm thinking about buying a second one so I can keep one in each vehicle.

Ahh... Not all the same...

There is a change in standards... Some people look to use these tools for other vehicles they might own. Some of the cheaper ones will not work on the newer GM and Ford vehicles.

So now showing both tables the OBDLink MX series can do a few more protocols that ELM can't. So they are not all the same. True the base design came from the ELM32x chips but other manufacturers have improved on the design considerably. 

 

So like here is the firmware updates for the OBDLink MX series. Depending on the ELM series you got and how cheap there might not be any updates to cover future vehicles. Again too cheap might limit abilities.
