Re: Toyota Previa diesel 2002 lack of power valve timing?

No. Just can't make any sense of the information you are providing? Trying to figure out what I am missing that you are seeing?

Re: Toyota Previa diesel 2002 lack of power valve timing?

How on earth does an exhaust valve open 18 degrees after the intake valve? That makes no sense? How have you worked out when the EVO is in regard to crankshaft degrees? I still can't see any IVO or EVO in the last upload? Are we missing something here?

Re: Toyota Previa diesel 2002 lack of power valve timing?

Sorry for my lack of knowledge but how do you use exhaust lifter operation portion of 57.75 camshaft degrees to check the EVO against crankshaft degrees on the in cylinder pressure waveform? Surely you need to know the EVO or IVO in reference to crankshaft degrees?

Re: Toyota Previa diesel 2002 lack of power valve timing?

Hi thanks for the reply. I have tried to find Valve open and closing times for that engine with no success. I have always found it nearly impossible to find that data on any engine. I Also think the EVO is early which means it shuts early which means the piston is still in the upward direction again...

Toyota Previa diesel 2002 lack of power valve timing?

Hi guys I have a 2.0L Diesel D4D chassis number JTEGG32MX00009571. Its lacking power all the way through rev range (Feels like turbo is in-op) Visually turbo intake turbine looks fine (no free play) manually operating vanes on turbo makes little to no difference to boost pressure. EGR appears to ope...

Re: 2004 Rover 75 2L Diesel no start

After nothing but time, Patience and shear pain we got BBA (who couldn't test it) to suck the software from the ECU and put it into another ECU and it still didn't start with exactly the same fault. With literally nothing else left to do we reloaded the same software version in to it using the T4 an...

Re: 2004 Rover 75 2L Diesel no start

I'll check powers and grounds at ECU when I get a chance. Any ideas what could cause this?? as cam vs crank would appear to be good. Thankyou

Re: 2004 Rover 75 2L Diesel no start

got a known good cam vs crank from a freelander (see waveform below) they are not identical but close enough in my opinion. What I did notice is the injector current on the faulty Rover 75 is not right. The injector is only drawing a maximum of 5 A and being fired at the wrong time on faulty vehicle...
