I am fairly sure he would want to know what motor this is from

No, that would take all of the challenge out of the guessing contest.

At least rod will know that it is a small HPDI.

Would also be nice to know why the question is being posted. Is there a problem or ???

You gotta love modern electronics. 2 milliseconds is a short period of time. Now image the .12 in the 2.12 milliseconds. That is .00012 of a second. How much more fuel can flow through an injector at 2.13 milliseconds versus 2.12 milliseconds?

[robert graham]

Did you catch any fish?....

[mrpontoon]

2003 z200 hpdi last week it would not power up past 4000 rpm
max rpm 4575

[rodbolt17]

O2 sensor voltage is a bit off.
have you inspected the plugs?
the z200 likes to eat them.
have you checked the lift pumps for leaking?

[boscoe99]

Does a bad spark plug possibly resulting in incomplete combustion, or a fuel pump leaking gasoline into the motor, cause the O2 sensor to indicate a rich mixture in the form of a higher voltage?

Is it the high O2 sensor voltage that is causing you to suspect the plugs or the fuel pump?

[ausnoelm]

2003 z200 hpdi last week it would not power up past 4000 rpm
max rpm 4575

Does this mean your max RPM is only 4575 when the motor is running OK?

[mrpontoon]

did get 5200 rpm before
plugs are 10 hours old but will check them today,allso will check the lp pumps
thanks will let you know

[greasyshaft]

Tighten up the mixture screw underneath the turbo
the oxygen sensor should not be reading in volts oxygen is measured as ppm (parts per million)

[bajakeith]

Omg !!

A OX sensor Does read in volts.. Its a very small output,, But it is in volts.. Plain and simple.. And that's coming from a MASTER Tech with 35 + yr's working as a Electrical and Fuel Injection Spe******t....

[rodbolt17]

the 2.6L Z motors use the O2 sensor for fuel trim below about 1500 RPM. the ECU does not act upon O2 sensor feed back above about 1500.
however
if the O2 sensor feedback is incorrect at low speeds the engine will perform poorly at high speeds.

cause there is a reason for the incorrect/poor feedback at low speed.

the Z200 was rather hard on spark plugs,especially at extended speeds between about 1000-1400.
some will foul plugs in less than 3 hours.

[mrpontoon]

check lp pumps 1 was leaking replaced both
checked plugs i found 1 the look new.check spark ok.after runing injector test with the yds i checked the plug it was wet.allso i checked the vst pump it was at 64 lbs and dropped to 20 relatively fast

[rodbolt17]

64 PSI is a tad high,may check the return filter.
the drop is normal.

[mrpontoon]

is that the filter in the pressure regulater
