Hello and Welcome to Justanswer, My name is XXXXX XXXXX I am here to try and assist your with your question
need to have the computer checked for codes
the light comes on because you have a code in the computer.
any questions on what I typed?
its beeen on the computer at work already..the codes were somthing like..no rpm signal, and to more realting to the fuel pump
what is the code?
p0725 is a trans code is oss sensor on the trans
need to look up the other codes do you know what they are?
injection pump no rpm from ecu
rpm sensor no signal
the light only really comes on when van is cold
sounds like you have a good start need to diag the codes
thats what im stuck with ?
what is that?
what the codes mean
ill se what I can find hang on
P1375 Ignition coil - Cylinder #5 - Early activation fault
so would igntion coil ?
p1635 is engine control module defective
I would say the computer need replaced and will solve all the codes
the computer tht controls everthing
but if the ecu was faulty wouldnt it come up with more dtcs than that
no not really this is just a hunch what you need to do is run a pinpoint test for each code
i dont no if this sounds stupid but...rpm sensor no signal does that not sound like crank sensor
P1335 Pump control module; crank position signal absent.P1635 Glow-plug control module; circuit malfunction in the control signal.P0725 Engine RPM input; circuit malfunction.
On the research i have done it is a bad ecu without doing the pinpoint test
I would strongly recomend you preform a pinpoint test for each code
sorry on the first code meant
it just seems strange that its only from cold
THATS IS THE WAY IT IS SOMETIMES
preform a pinpoint test
